Specialists In Water Resources Economics City of Ocoee RPF� Water and Wastewater Rate Study 9 Executive Summary This executive summary presents the results of the water and wastewater rate study conducted for the City by Burton & Associates. This executive summary is intended to present only the summary results and we recommend that the report be read in its entirety for a thorough understanding of the methodology and underlying analyses that support the results presented herein. A. Objective and Scope The objective and scope of this Study were to: 1. Conduct an evaluation of the sufficiency of the City's water and wastewater rates to fully fund all operations, maintenance, renewal and replacement and capital costs of the utility for a five year projection period, 2. Develop a reclaimed water rate program, and 3. Conduct an analysis of the City's water and wastewater rate structure to identify any changes to: a) Ensure fair and equitable recovery of the costs of service and b) Provide incentives for water conservation in the context of the other water conservation initiatives being undertaken by the City. B. Study Procedures In the conduct of the Study, we employed our automated interactive process to develop an integrated solution, in concert with City staff, that fully evaluated all possible alternatives available to the City. Through this interactive process, we were able to develop a recommended water, wastewater and reclaimed water rate program that fully funds the requirements of the utilities over the next five years, with minimal impact upon the rate payers.

The recommendations presented in the following section provide for a financial management plan for the water, wastewater and reclaimed water utilities of the City that achieves the following: 1. Minimizes the impact of required water and wastewater rate increases by use of an annual inflationary indexing rate adjustment plan, 2. Provides a rational reclaimed water rate program in recognition of the limitations of market pricing realities, 3. Provides funding for the reclaimed water program, without the need for an up-front capacity fee, and 4. Provides for water conservation incentives in the recommended adjustments to the water rate structure by applying all annual water and wastewater rate adjustments to only the usage rate portion of the rates. D. Recommendations .. In order to achieve the results presented in the prior section, we recommend the following: 1. Implement annual water and wastewater rate indexing adjustments to provide for a 3% annual increase in water and wastewater rate revenues. The first of such rate indexing adjustments should take effect March 1, 2001 and subsequent indexing adjustments should take effect on October 1, 2001 through October 1, 2005. 2. Implement the above referenced rate indexing adjustments by adjusting only the water and wastewater usage rate by 6%per year. This will a)cause the average residential rate payer's monthly water and wastewater bill to increase by approximately 3% per month,b)will achieve the required 3%annual increase in water and wastewater rate revenues and c) will provide a water conservation incentive by implementation of annual increases in the water and wastewater usage charge, which over the five year The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study -ii- Water Resources Economics DRAFT rate plan, will shift a significant percentage of the rate impact from the fixed charge to the usage charge. Note: In light of all of the water conservation initiatives being implemented by the City, namely the water conservation public relations program, the reclaimed water program and this rate structure recommendation, we believe that this rate structure recommendation, in combination with the other two conservation initiatives, will provide incentives to conserve potable water and would expect to see reductions in potable water usage per equivalent dwelling unit within the City over the five year projection period. 3. Connect only New (new construction) and Bulk (greater than 3"meters) reclaimed water customers through Fiscal Year 2002, at which time Retrofit (existing construction)reclaimed water customers can be connected. This will allow the above recommended water and wastewater rate indexing adjustments to provide the level of revenue generation required to fully fund all of the capital costs of the Retrofit reclaimed water customers. a 4. Implement reclaimed water rates with a fixed monthly charge based upon the meter size with an allowed monthly reclaimed water usage amount and a rate per 1,000 gallons for all reclaimed water usage in excess of the monthly allowance. Specific recommended reclaimed water rates are presented in Figure 1 of Appendix B to this Report.

Introduction _ This report presents the results of the Water and Wastewater Rate Study conducted by Burton & Associates for The City of Ocoee. This section of the report presents the objective of the Study, the scope of the work conducted and the Study procedures employed in the conduct of the Study. A. Objective The objective of this Study was to develop 1) an evaluation of the ability of the City's water and wastewater utilities to provide sufficient revenue to cover all revenue requirements over a four year forecast period, 2) proposed reclaimed water rates and 3) an analysis of the City's water and wastewater rate structure. B. Scope 1. Revenue Sufficiency Analysis Scope The scope of the Revenue Sufficiency Analysis portion of the Study was to develop a financial management plan for the water and wastewater system during a four year forecast period. The results of this Study present a plan, or blueprint, that, with annual updates, verifications and adjustments, will serve to guide the financial management of the water and wastewater systems over the four years of the forecast period. This report presents the results of a four year revenue sufficiency analysis for the water and wastewater systems which includes a four year financial management plan. The four year financial management plan identifies the following.

Reclaimed Water Rates Scope The scope of this Study included the development of reclaimed water rates, consistent with the market for reclaimed water, that can be implemented on a City- wide basis for identified classes of reclaimed water service. The scope also included a determination of the range of impact,for specific implementation scenarios,in terms of water and wastewater rate increases that will be required to 1) recover reclaimed water costs that are not recoverable from the reclaimed water rates and 2)counteract the potable water offset effect,or conservation effect,of potential revenue losses from the substitution of reclaimed water usage for potable water usage because of the loss of water and wastewater billing units. The scope included the development of reclaimed water rates for the following classes of reclaimed water customers: • Retail - Retrofit - These are reclaimed water customers that are currently City water customers and provision of' reclaimed water service would require retrofitting reclaimed water transmission and distribution lines in existing developments and neighborhoods. • Retail- New - These are reclaimed water customers that connect to the reclaimed water system as new homes or businesses. For these customers, it is assumed that the reclaimed water distribution system will be installed by the developer and contributed to the City. _ • Bulk Users - These are reclaimed water customers that receive reclaimed water on a bulk volume basis. These customers do not require a distribution system to provide them service or they provide their own distribution system behind the bulk meter through which the City provides reclaimed water. 3.

Study Procedures In order to complete this Study, we completed activities in four areas of work as follows: I. Data Gathering and Compilation In this area of work we obtained copies of all relevant data and information including prior rate studies, historical and current financial statements and budgets, the current rate ordinance(s), customer and billing information, the current capital structure,capital improvement programs,existing and planned system configurations and other information provided to us by City staff 2. Analysts and Evaluation After obtaining the above referenced data and information, we met with members of City staff to ensure that we understood all data and information obtained and to gain a better understanding of management philosophies, goals and objectives regarding the ongoing management of the water, wastewater and reclaimed water systems. We then 1) conducted an analysis of the sufficiency of the water and wastewater system revenues over a four year projection period from FY 2001 through FY 2004 and developed a four year financial management plan by using our proprietary Funding Analysis and Management System(FAMS)model,2)conducted an analysis of the reclaimed water system service delivery alternatives identified by City staff and developed an analysis of the reclaimed water rates for each type of reclaimed water service identified by using our proprietary reclaimed water financial model, and 3) conducted an evaluation of the City's current water and wastewater rate structure. The City of Ocoee Burton &Associates Water and Wastewater Rate Study Water Resources Economics _4_ 3. Interactive Work Sessions We then conducted interactive work sessions with City staff. In these interactive work sessions, we presented the results of our revenue sufficiency and reclaimed water analyses and discussed in detail the assumptions and reconciliations to the City's budget for each utility. We identified our initial revenue sufficiency analysis, which conforms with the City's budget, as the Baseline Alternative. We displayed the results of our analysis in graphical format with our revenue sufficiency and reclaimed water rate models up and running. In the revenue sufficiency analysis,the graphs displayed showed four year bar charts for each of the following financial indicators simultaneously: • Percent increase in rate revenue required in each year • Annual debt service amount and debt service coverage provided in each year • Balance of unrestricted reserves by year • Borrowing requirement by year • Total amount of capital improvement program by year We demonstrated the impact of various changes in assumptions, capital improvements program amounts and other parameters of the model in order to identify, with City staff, the financial management plan included in this report. In the reclaimed water analysis, we demonstrated the impact of various changes in assumptions, customer subscription rates and other parameters of the model in order to identify, with City stab, the most appropriate allocation of costs in the development of reclaimed water rates for each identified class of reclaimed water service.

Revenue Sufficiency Analysis This section presents the results of the revenue sufficiency analysis and financial management program development portion of the Study. As was described in Section I.C. - Study Procedures, we identified our initial analysis, which conforms to the City's budget, as the Baseline Alternative. We presented the results of our revenue sufficiency analyses in interactive work sessions with City staff and discussed in detail the assumptions and reconciliations to the City's budget. We displayed the results of our analysis in graphical format with our FAMS model up and running. The graphs displayed showed four year bar charts for each of the following financial indicators simultaneously: Percent increase in rate revenue required in each year • Annual debt service amount and debt service coverage provided in each year • Balance of unrestricted reserves by year • Borrowing requirement by year • Total amount of capital improvement program by year We demonstrated the impact of various changes in assumptions, capital improvements program amounts and other parameters. After review of the Revenue Sufficiency analysis with City staff it was determined that, under the assumptions presented in this report, no rate increases would be necessary in order for the financial requirements of the water and wastewater system to be met in each year of the forecast period. The following subsection presents the assumptions used in the development of the financial management plan and the subsequent subsection presents the results of the proposed financial management plan. The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -7- A. Assumptions The assumptions included in the development of the financial management plan are as follows: • Growth: • Growth in Rate Revenues - Growth in rate revenues was projected using growth projections for water and wastewater from the City. These growth projections ranged from a high in FY 2001 of 3.46%to a low of 3.14%in FY 2004 for water. Growth projections for wastewater ranged from a high of 7.55% in FY 2001 to a low of 6.15% in FY 2004. • Growth in Development Fee Revenues-Growth in development fee revenues was projected based upon the City's projected annual growth of400 ERCs for both water and wastewater. • Operations and maintenance cost escalation- Operations and maintenance expenses for FY 2001 reflect the City's budgeted expenses. For the remainder of the forecast period, operating expenses have been escalated by a 3% cost escalation factor and 25% of growth. This results in a range of cost escalation factors during the forecast period of 3.87%in FY 2001 to 3.78%in FY 2004 for water, and 4.89% in FY 2001 to 4.54% in FY 2004 for wastewater. • Minimum working capital balance in unrestricted reserves-An amount equal to three (3)months of operations and maintenance expenses is reserved as a minimum working capital balance. • Investment interest earnings-Investment interest earnings were calculated on average balances at 5.30% for FY 2001, 4.30% for FY 2002 through FY 2004. • Capital projects funding- Water and wastewater development fee revenue was not used in projecting the funding of capital projects. This is because the City currently uses water and wastewater development fee revenues to pay the portion of the annual debt service that resulted from the issuance of Revenue Bonds in 1993 and 1997. The City of Ocoee Burton &Associates Water and Wastewater Rate Study Water Resources Economics -8- r , Therefore, the only"non-debt" source of funds available to fund capital projects is unrestricted reserves, which were applied to unfunded project balances. Any project balances unfunded after application of all available sources of funds would be included in the borrowing requirements for each year. However, it was projected that no borrowing would be required during the forecast period. • Borrowing assumptions - Had any borrowing requirements been identified, the resultant borrowing and annual debt service would be calculated based upon the assumption of a 30 year term for revenue bonds at 6.0% interest; one year's debt service for a debt service reserve fund; costs of issuance to include underwriters discount at 1%of par amount, bond insurance at .25%of par amount and other costs of issuance at .75%of par amount. If any borrowing were projected, it was assumed to occur on October 1 in all years where it is required. • Debt service coverage - There are four debt service coverage tests in the City's outstanding bond covenants as follows: Rate covenant: • Net income must be equal to 1.00 times annual debt service, and • Net income plus development fees must be equal to 1.10 times annual debt service. Parity test - • Net income must be equal to 1.00 times maximum annual debt service(applies only in years when revenue bonds are issued), and • Net income plus development fees must be equal to 1.10 times maximum annual debt service (applies only in years when revenue bonds are issued). The following subsections present the results of the revenue sufficiency analysis and the proposed financial management plan.

Enterprise Fund The City of Ocoee's water and wastewater systems are considered as one enterprise fund in the City's budget and accounting system and the combined revenues of both the water and wastewater systems are pledged revenues for the City's outstanding water and wastewater revenue bonds. 2. Capital Improvements Program The four year capital improvements program (CIP) that was used in the development of all of the financial management plan scenarios is presented in Figure 3 in the Exhibits Appendix of this Report. Figure 3 presents the water and wastewater utility capital improvements program. The proposed financial management plan presented herein provides sufficient funds to finance this CIP in all years of the four year forecast period. 3. Financial Management Plan The proposed financial management plan will not require any rate increases during the four year forecast period, (FY 2001 -FY 2004), in order for the water and wastewater utility to meet all a necessary financial requirements during the forecast period. The results of the revenue sufficiency analysis and financial management plan development are presented in the graphs and schedules in the Exhibits Appendix at the end of this Report. The first exhibit , Figure 1, presents the control panel used in the interactive workshops with City staff. This figure shows graphical representations of the CIP,the percentage rate revenue increases required(in this case no rate increases are required), the annual debt service and debt service coverage, annual borrowing required, and the end-of—year unrestricted fund balances(working capital reserve funds). Figure 2-A presents the Financial Results of Operations with Computation of Debt Service Coverage for each year of the forecast period. Figure 2-A demonstrates that the rate plan will The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -10- L provide sufficient revenue to pay all operations and maintenance expenses and will provide adequate debt service coverage in all years of the forecast period. Figure 2-A also demonstrates that the rate plan will generate sufficient cash to not only pay all operations and maintenance expenses and provide adequate debt service coverage,but also will pay all minor capital outlay expenses and other"below the line" expenses. Figure 2-B presents the Sources and Uses of Funds which demonstrates that the rate plan will provide sufficient resources to fund the CIP projects in all years of the forecast period. Figure 2-C presents Changes in Account Balances during the forecast period. This figure shows the fund activity and beginning and end of year fund balances in all funds for each year of the forecast period. Figure 4 presents the Annual Project Funding Summary during the forecast period. This figure provides a detailed listing of water and wastewater capital projects, as provided in the City's CIP,and the most effective means by which each project can be funded. The Annual Project Funding Summary lists sources of funds available to pay for capital projects, i.e. water development fees, wastewater developments fees, 1997 Revenue Bond proceeds and the Operating Fund revenue. It then shows the how each project in the CIP was projected to be funded within the financial ' management plan presented in this Report. 4. Summary of Results a. Rate Revenues Combined water and wastewater rate revenues for FY 2001 are estimated to be$4,085,000. These rate revenues are projected to increase by the assumed growth rate for each year in the forecast period resulting in projected combined water and wastewater rate revenues of$4,721,000 in FY 2004, the last year of the forecast period. No rate increases will be required during the period. The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -11- - I -'� r Fri LJ 2 _ b. Operations and Maintenance Expenses Combined water and wastewater operations and maintenance expenses for FY 2001 are estimated to be$3,302,000.These O&M expenses are projected to increase by the cost escalation factor of 3%and 25%of the assumed growth rate for each year in the forecast period. This results in projected O&M expenses of$3,723,000 in FY 2004, the last year of the forecast period. c. Capital Improvements Program ' The proposed financial management plan will fund approximately $984,000 of water projects and $2,715,000 of wastewater projects for a total of$3,699,000 during the four year forecast period, FY 2001 through FY 2004. All capital projects funding during the forecast period are funded with reserves and current revenues. d. Debt Service The City's current water and wastewater annual debt service ranges from a low during the forecast period of approximately $1,342,000 in FY 2002 to a high of approximately $1,347,000 in FY 2004. Debt service remains basically unchanged during the forecast period because no additional debt is incurred to fund capital projects during the forecast period. e. Unrestricted Fund Balances Need to update per September 30, 2000 CAFR. f Development Fee Fund Balances Need to update per September 30,2000 CAFR.

Debt Service Coverage Debt service by net income during the four year forecast period ranges from a high of 1.29 in FY 2004 to a low of 1.13 in FY 2001. Debt service coverage by net income+ development fees during the forecast period ranges from a high of 2.23 in FY 2004 to a low of 2.08 in FY 2001. There is no parity test coverage during the forecast period due to the fact that no additional debt is projected to be issued during the forecast period. a a The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -13- III. Reclaimed Water Rates This section presents the results of the revenue sufficiency analysis and financial management program development portion of the Study. A. Basis of the Analysis In order to develop fair and equitable reclaimed water rates it is first necessary to determine the cost of providing reclaimed water service for each identified class of service. To the extent that the cost to provide service is greater than the market rate that is feasible relative to alternative sources of irrigation water available to potential reclaimed water customers,the rate must be set at the market rate and the excess costs to provide the service must be absorbed in the water and/or wastewater rates. To the extent that the cost to provide service is less than the market rate, the rate should be set at the cost to provide the service. In order to determine the cost of providing reclaimed water service to the classes of service identified, it was first necessary to establish a baseline class of service to use as the basis for determining the total cost to provide reclaimed water on an equivalent residential unit (ERU)basis. _ The Retail-New class of service was identified as the baseline class of service. It was determined that the cost to provide service to both the Retail-Retrofit and the Retail-New classes differ only by the cost of the distribution system, which is contributed by the developer for a Retail - New customer and would be incurred as an additional cost to the Retail- Retrofit customer. Therefore, to the extent that the market would allow, the monthly rates for the Retail-Retrofit class would be greater than the monthly rates for the Retail-New class in order to reflect the additional cost of the distribution system for the Retail-Retrofit class. In the event that the market rate would not recover any portion of the distribution costs for the Retail - Retrofit class, those costs would need to be recovered through some other means, most likely an increase in the water and wastewater rates. a In order to arrive at the rates presented in this report, an analysis of the cost to serve each identified class of service was performed with City staff and any appropriate adjustments were made a in order to reflect the appropriate cost to provide service to each class of service. The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -14- L In order to calculate the cost of providing reclaimed water service on an EAU basis it was necessary to establish a prototypical service area for which cost estimates could be made for the various functional components of reclaimed water cost. We worked with City staff to determine the impact of various levels of buildout of the reclaimed water system in order to arrive at a proposed implementation program that would provide reclaimed water service to the most customers while a minimizing the impact to the water and sewer rates. Due to the nature of the analysis required and the limited data currently available with respect to estimated operations and maintenance(O&M) and capital costs for the reclaimed water system, Burton&Associates provided industry standards for O&M and capital costs where that data was not readily available. These industry standard costs were applied on a cost per ERU basis to the proposed implementation program to determine the total cost of the proposed implementation program. The total cost to provide reclaimed water service on an ERU basis was calculated as described a above for each class of service identified, with the cost of Bulk service being expressed as a rate per 1,000 gallons. These costs per ERU were then compared to the market rate per EAU for reclaimed water. The market rate was established as being equal to approximately 75% of the cost per ERU, at current City water rates, of the potable water that the average customer uses now for irrigation. The average amount of potable water per ERU now used for irrigation was estimated based upon an analysis of the water usage profiles of the City's current reclaimed water customers (who are presently using potable water). This was done by identifying all reclaimed water customers and performing a usage analysis upon their most current 12 month consumption history. It was determined through our discussions with City staff regarding this analysis that, for the purposes of this reclaimed water analysis, the average reclaimed water user's consumption was estimated to be 20,000 gallons per month, with consumption beginning at 10,000 gallons per month. This average usage per customer was considered to be the standard irrigation usage per ERU.This irrigation usage per ERU was also used to convert the costs calculated on an ERU basis to a rate per 1,000 gallons of usage for Bulk customers. a The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -15- Ll B. Results This section presents the results of the Study. The first subsection presents an overview discussion of a reclaimed water program and the financial dynamics between the reclaimed water program and the water and wastewater rates. The next subsections present a summary of assumptions, the results of the study, the recommended reclaimed water rates for each reclaimed water class of service identified,and a recommended implementation program for the reclaimed water system. 1. Overview In the evaluation of a reclaimed water program it is important to understand ' that reclaimed water rates will be dictated by market pricing forces rather than the cost to provide the service. This is because potential reclaimed water customers have alternatives for irrigation, the most readily available of which is potable water. Therefore, the price of reclaimed water must be no more than the cost of potable water now used for irrigation or the customer will probably choose to continue to irrigate with potable water. Our experience has been that in order for a reclaimed water rate to compete with potable water as an alternative for irrigation it must be set at a rate equivalent to from 50%to 75% of the cost of potable water currently used for irrigation. If the cost to provide reclaimed water is more than the revenue that will be derived from setting the rates at the determined percentage of the potable water cost for irrigation, the unrecovered costs must be allocated to the water and/or sewer rates and may require an increase in water and/or sewer rates to cover these costs. Also,when reclaimed water is substituted for potable water for irrigation,the City will lose billing units for water and, if the water rate is not increased, it will lose water revenue. To the extent that the existing water rate structure inclines in the usage range where it is estimated that reclaimed water usage would happen, the "substitution" effect described above would be exacerbated. This phenomenon is a typically referred to as the potable water offset effect. Reclaimed water substitution for potable water usage for irrigation also effects wastewater revenue if there is no cap, or a high cap, on residential wastewater billings. The City caps residential The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics -16- - • L2 wastewater billings at 12,000 gallons per month, therefore, there will be some loss of wastewater billing units (from 10,000 to 12,000) in addition to the loss of water billing units caused by the potable water offset effect, or substitution effect. In order to maintain the current level of water and wastewater revenues after the implementation of a reclaimed water program,water and wastewater rates may have to be increased to counteract this potable water offset effect. 2. Summary of Assumptions We developed recommended reclaimed water rates for the following classes of reclaimed water service: a. Retail-Retrofit-These are reclaimed water customers that are currently City water customers and provision of reclaimed water service would require retrofitting reclaimed water transmission and distribution lines in existing developments and neighborhoods. _ b. Retail - New - These are reclaimed water customers that connect to the reclaimed water system as new homes or businesses. For these customers, it is assumed that the reclaimed water distribution system will be installed by the developer and contributed to the City. c. Bulk Users - These are reclaimed water customers that receive reclaimed water on a bulk volume basis. These customers do not require a distribution system to provide them service or they provide their own distribution system behind the bulk meter through which the City provides reclaimed water. Major assumptions included in the development of the reclaimed water rates presented herein are as follows: • Grants-It is assumed that no grants will be received for any portion of the estimated reclaimed water costs. • Funding of capital costs - All capital costs will be funded by the issuance of revenue bonds and the annual debt service of those bonds is included as an annual reclaimed water cost. The City of Ocoee Burton &Associates Water and Wastewater Rate Study Water Resources Economics -17- • Rates-Reclaimed water rates will be set at a level equal to the lessor of cost or 75% of the current cost of potable water per ERU in the range in which irrigation normally occurs. • Rate structure-The reclaimed water rates are assumed not to include an availability charge to all customers to whom the service is available whether they connect or not. Such an availability charge could be included in the rate structure, however, it was not included in this analysis in order to present as conservative an analysis of reclaimed water revenues as possible. • Reclaimed water costs in excess of reclaimed water revenue-Where reclaimed water costs exceed reclaimed water revenue, the unrecovered reclaimed water costs will be allocated to the water and wastewater rates in proportion to each systems revenue as a percent of combined water and wastewater rate revenue. • Potable water offset - It is assumed that the water and wastewater revenue losses that would occur due to the loss of billing units caused by the substitution of reclaimed water for potable water for irrigation will be countered with increases in the water and wastewater rates in order to remain revenue neutral. 3. Results This section presents the recommended reclaimed water rates as unit charges per ERU and per 1,000 gallons. However, in order to implement reclaimed water rates, a specific rate structure must be adopted. Such rate structures typically include a fixed charge per month and a usage charge per 1,000 gallons. Therefore, a specific recommended rate structure with specific rates for each rate component for each class of service is presented in Section II.C.2 Rate Structure Recommendations. a. Summary of Results Figure 2 presents the calculation of the cost of providing reclaimed water to each identified class of customer. Figure 2 shows that the cost to The City of Ocoee Burton &Associates Water and Wastewater Rate Study Water Resources Economics -18- Li ll• provide reclaimed water service for the Retail - Retrofit class is $33.43 per ERU, or $1.67 per 1,000 gallons, and the cost to provide reclaimed water service for the Retail-New class of service is $11.98 per ERU, or$0.60 per 1,000 gallons. The cost to provide service to both the Retail-Retrofit class of service and the Retail-New class of service, $33.43 per ERU and $11.98 •- per ERU respectively, are greater than the market rate of$7.65 per ERU, which represents 75%of the current cost per ERU of potable water used for irrigation. Therefore, the recommended rate for the Retail class of service is the market rate of$7.65 per ERU, or$0.38 per 1,000 gallons. Rate structure recommendations are presented in Figure 1. Figure 2 shows that the cost to provide Bulk reclaimed water service is $0.40 per 1,000 gallons, and that the market rate for Bulk reclaimed water service is $0.38 per 1,000 gallons. b. Reclaimed Water Rate Structure Recommendations Recommended reclaimed water rates per ERU and per 1,000 gallons of usage were presented in the previous section. However, in order to implement a reclaimed water rate program, a specific rate structure must be adopted_ The alternatives for reclaimed water rate structures range from a fixed charge per month per ERU for unlimited reclaimed water usage to a rate per 1,000 gallons for all reclaimed water usage. In order to provide fiscal security relative to the City's reclaimed water rate revenues and a predictable, yet controllable cost for the City's reclaimed water customers, we recommend a rate structure that combines elements of both of the above approaches for Retail-Retrofit, Retail-New and Bulk reclaimed water customers. We recommend adoption of I) a fixed monthly charge for the Retail - Retrofit, Retail - New and Bulk customer .. classes equal to the recommended monthly rate per ERU, based upon meter size equivalencies, with a monthly usage allowance of 12,000 gallons of reclaimed water for a 5/8"x 3/4" meter, and a proportionately similar type of The City of Ocoee Burton &Associates Water and Wastewater Rate Study Water Resources Economics -19- i ' usage allowance adjusted to reflect the increased flow capability of larger meter sizes, and 2)a rate per 1,000 gallons of usage above the monthly usage allowance, based upon meter size equivalencies, equal to the recommended rate per 1,000 gallons. Based upon these rate structure recommendations, we recommend adoption of the reclaimed water rate schedules presented in Figure 1. c. Supporting Schedules This subsection presents the schedules which contain the analyses that support the results presented in the previous subsection. The schedules included are as follows: Figure 1 - Proposed Reclaimed Water Presents a schedule of proposed reclaimed water rates and Rates and Rate Structure rate structure by customer class and by meter size. Figure 2- Rate Computations Presents a summary of the computation of the cost per ERU for all classes of service and the recommended rates for each class of service Figure 3- Units Analysis Presents the estimated reclaimed water customers and ERUs for the prototypical service areas used in the computation of City-wide reclaimed water rates 4. Impact Upon Water and Wastewater Rates In order for a reclaimed water system to be viable, any costs not recovered through the reclaimed water revenue must be recovered through some other means,usually the water and wastewater system. Therefore,a logical issue that arises in consideration ofa reclaimed water system is the impact upon the water and wastewater rates. As discussed in prior sections of this report, there are two components to the impact upon the water and wastewater rates. The first component is net income(loss) generated by the reclaimed water system. To the extent that it costs more to provide reclaimed water than can be generated through the market-based rates necessary for reclaimed water,a net loss will occur in the reclaimed water The City of Ocoee Burton &Associates Water and Wastewater Rate Study Water Resources Economics -20- DRAFT system. This net loss must be allocated to the water and wastewater revenue and to the extent that there is not enough water and wastewater revenue available to make up this net loss, it must be recovered through an increase to the water and wastewater rates. The second component to the impact upon the water and wastewater rates is the potable offset effect, or"substitution" effect, of current water and wastewater customers switching from potable water to reclaimed water. As outlined in prior sections,the reclaimed water rate must be less than the potable water rate in order for customers to have an incentive to use reclaimed water. If the same usage occurs, but at a lower rate, revenue that is lost from the water system will not be recovered completely from the reclaimed water system. Therefore, this potable offset effect must be recovered through the water and wastewater revenues and an increase to the water and wastewater rates will likely be necessary. a In order to minimize increases while maximizing the number of customers for which reclaimed water can be made available, a rational implementation plan must be developed. The section below outlines a plan that should accomplish both of these goals. Under the assumptions developed in our worksessions with City staff, the plan presented should allow the City to provide reclaimed water to as many customers as is economically feasible and at the same time minimize the impact to the water and wastewater rates. 5. Recommendations In order to maximize the number of customers that will receive reclaimed water service _ while minimizing the impact to the current water and wastewater rates, a rational implementation plan must be developed for the reclaimed water system. The following are recommendations with respect to the implementation of the reclaimed water system. 1. Begin annual indexing, or rate increases, to apply to the City's water and _ wastewater rates and charges,including impact fees,beginning March 1,2001 and on October 1, 2002 through 2005. A common annual indexing factor, which we recommend,is 3%,which provides the water and wastewater utility some protection against inflationary pressures.It is also recommended that the The City of Ocoee Burton 8 Associates Water and Wastewater Rate Study Water Resources Economics _21_ DRAFT City apply the same annual indexing to the reclaimed water rates and charges so as to maintain a steady relationship between potable water and reclaimed water rates. 2. Connect only Retail -New and Bulk customers during the first 2 years of the reclaimed water program. In order for the reclaimed water system to become a viable utility, customer classes that require much more expense than the revenue they generate,as does the Retail-Retrofit class, must be limited until the water and wastewater utility has more ability,through the annual indexing recommended in item 1, to absorb unrecovered costs associated with the connection of Retail - Retrofit customers, which is projected to occur after approximately 2 years. 3. Implement reclaimed water rates in accordance with the rate structure recommendations presented in Figure 1 of the Exhibits Appendix B - Reclaimed Water Rates Analysis.
