MEMORANDUM
DATE: October 8, 1997
TO: The Honorable Mayor and Board of City Commissioners
FROM: James W. Shira, P.E
City Engineer/Utilif rector
SUBJECT: Joint Ocoee/Winter Garden Water Reuse Planning
One of the major issues facing municipal utilities is the proper conservation of our limited water
resources. Florida's fast growing population, with its ever increasing demand for water has made
it clear that alternate sources for non-drinking water must be found and exploited. One of the
most promising of these sources is highly treated wastewater treatment plant effluent, commonly
called reclaimed water. The City of Ocoee currently uses reclaimed water to irrigate the Forest
Lake golf course. This practice "saves"nearly one million gallons of water each day that would
otherwise be taken from our drinking water supply. Permitting agencies are taking an
increasingly hard line toward utilities to require that they implement reclaimed water systems to
the greatest degree possible. Ocoee's Consumptive Use Permit, issued by the St. John's River
Water Management District(SJRWMD) requires that we expand our reclaimed water system to
serve residential and commercial areas. The City of Winter Garden faces similar restrictions on
its utility system. Over the past several months we have been talking to representatives of the
City of Winter Garden, the SJRWMD and the Florida Department of Environmental Protection
(FDEP) about the possibility of addressing both cities' reclaimed water concerns with a single
project.
Under"normal" circumstances, both the City of Ocoee and the City of Winter Garden would
design, construct and operate their own reclaimed water system without regard for the economies
of scale that can be achieved with a single large system. Both of these systems would be subject
to expensive wet weather disposal requirements and would likely compete for discharge rights
into Lake Apopka. In addition, each system would probably find that at times during the year,
demand for reclaimed water would exceed the available supply. This would result in a
consumer's lack of confidence in the system,with a resultant return by many of those consumers
to using potable water for irrigation purposes.
Our proposal provides for Winter Garden to supply.reclaimed water to the Forest Lake golf
course, allowing Ocoee to send its reclaimed water to residential and commercial customers
THE PRIDE OF WEST ORANGE
along Clarke Road. During the rainy season when demand for reclaimed water falls, Ocoee
would direct its flow to the Winter Garden site. Winter Garden is currently permitted to
discharge their entire plant flow to this site,which ultimately drains to Lake Apopka. Any
normal domestic wastewater plant's effluent contains phosphorous in many different forms.
Phosphorous is a food source for the algae that clouds Lake Apopka, and for this reason,the
SJRWMD is trying to limit the amount of phosphorous entering the lake. Our proposal will help
accomplish that goal by requiring that the flows from both plants meet stringent chemical
analysis.
Winter Garden's city engineer and I met with representatives of SJRWMD and FDEP on
Monday, October 6, 1997 to propose this joint project between the two cities which we feel will
solve the problems of both, at a lower total cost to each. Both agencies were very receptive to
the concept we proposed, and suggested that we proceed with preparation of a report which will
provide more of the technical data required to support our proposal.
Attached for your review and approval is a proposal submitted by Andreyev Engineering, Inc. for
the work required to gather and analyze data from Ocoee's and Winter Garden's utility systems.
Using that data, Andreyev will prepare a conceptual plan for submission to FDEP and
SJRWMD. Upon approval of the conceptual plan by those agencies and by both cities, further
authorizations issued by each city will allow us to proceed with design of the specific
components of the joint system. The requested action before you is approval of Tasks 1 and 2 as
described in Andreyev's proposal, for a total fee of $3,466.00. This will be paid from the
proceeds of the 1997 Water & Sewer System Improvement Revenue Bonds, specifically from the
$1,500,000 earmarked for effluent disposal system expansion. An identical proposal will be
acted upon by the City of Winter Garden on October 23, 1997.
I recommend that the City Commission authorize Andreyev Engineering, Inc. to proceed with
Tasks 1 and 2 as outlined in their proposal number.NEA-97-081 for a not-to-exceed fee of
$3,466.00.

Attention: James W. Shira, P.E.
City Engineer
SUBJECT: Proposal, Engineering Services for Water Reuse Assessment and Permitting,
City of Winter Garden and City of Ocoee Wastewater Facilities
Orange County, Florida
Dear Mr Shira:
Per your request, Andreyev Engineering, Inc. (AEI) has prepared this proposal to provide
engineering services associated with planning, designing and permitting of an integrated water
reuse system between City of Winter Garden and City of Ocoee. Our services will include
providing the necessary engineering evaluation, selection of various alternative of water reuse,
assessment of the alternatives for implementation, evaluation of environmental concerns,
presentation of the conceptual plans to the SJRWMD and the FDEP, design of the selected
alternative for implementation and permitting. AEI has investigated and conducted groundwater
flow modeling for both wastewater facilities (Winter Garden and City of Ocoee) and is very
familiar with the overall needs of the two cities. We are also aware that both cities are mandated
by the SJRWMD to maximize water reuse within their services areas. The primary focus of the
proposed work is to combine the wastewater disposal facilities of the two cities, which will allow
optimization of the overall water reuse within the region.
The proposed scope of our work can be divided into four(4)tasks. The following is a brief
description of the proposed scope of work for each task:
Task 1 - Development of Conceptual Plan
For this task we propose to carry out the following engineering services:
1. Meet with the City of Winter Garden and City of Ocoee and collect all available data
concerning wastewater flows, potable water use, effluent disposal facilities, wastewater

distribution systems and other relevant information.
2. Review and evaluate collected data and develop a conceptual plan of water reuse for the
two cities.
3. Present the conceptual plan to the two cities and discuss potential changes, other
alternatives, new distribution and disposal systems, etc..
4. Modify conceptual plan, incorporating all suggestions and changes discussed during
presentation.
5. Present the conceptual plan once again to the two cities for final review and approval.
6. Make final changes, if any, and submit 5 copies of the final conceptual plan to the two
cities.
Task 2 - Conceptual Plan Approval by SJRWMD & FDEP
Our scope of work for this task will include meetings with SJRWMD and FDEP to present the
conceptual plan of wastewater disposal and water reuse. This presentation will be critical to the
successful completion of this project. The presentation of the plan will be to establish the
potential regulatory and permitting problems and identify the permitting requirements. At this
time, the following scope of work is anticipated:
1. Meet with SJRWMD to present the conceptual plan and discuss the selected alternatives
of effluent disposal and water reuse.
2. Meet with FDEP to present the conceptual plan and discuss the selected alternatives of
effluent disposal and water reuse.
3. Modify conceptual plan per regulatory agency comments and/or suggestions.
4. Meet with City of Winter Garden and City of Ocoee to present the modified conceptual
plan and discuss the selected alternatives of effluent disposal and water reuse.
5. Submit the final conceptual plan to the two cities for review and approval.
At the completion of this task, the water reuse plan will be completed and ready for design and
permitting. We anticipate that various permitting issues will be identified, such as direct discharge
to Lake Apopka, discharge to wetland systems, irrigation of existing and new sites, wet weather
disposal through percolation ponds, etc.. At this point a better definition of the scope of work for
Tasks 3 and 4 can be provided. The scope of work of Tasks 3 and 4, presented herein, is only
approximate and is intended for planning and budgetary purposes.
Task 3 - Design of Combined Water Reuse System
The design of the combined water reuse system will be based on the approved conceptual plan
developed in Tasks 1 and 2. We will prepare the necessary plans, engineering reports,
2
construction specifications and other supporting documentation that would be required for
permitting and construction of the water reuse facilities. Although the exact scope of work for
this task is not known at this time, we anticipate completing the following work, as a minimum:
1. Evaluate nutrient loading into Lake Apopka and wetland discharge areas.
2. Evaluate effluent disposal capacity of selected spray irrigation sites and percolation ponds.
3. Evaluate wetland impacts from construction activities and effluent disposal.
4. Groundwater flow modeling of selected new sites for effluent disposal.
5. Develop stormwater management plans for construction sites.
6. Prepare construction plans and specifications for the proposed combined water reuse
system retrofit projects.
7. Prepare engineering reports describing the proposed construction and implementation of
the projects.
8. Submit all reports, plans and specifications to City of Winter Garden and City of Ocoee
for review and approval.
9. Make final changes or modifications as needed.
Task 4- Obtain Permits from Regulatory Agencies
The scope of our work for this task will include compiling the necessary supporting
documentation for the required permit applications, submitting permits to the regulatory agencies
and responding to various comments. The following is a brief summary of anticipated work:
1. Prepare engineering reports to support permit applications.
2. Prepare permit applications with supporting documentation for submittal to SJRWMID and
FDEP.
3. Attend various meetings with the cities and regulatory agencies to discuss final design
plans and construction details, if necessary.
4. Prepare responses to SJRWN4D and FDEP comments and perform additional engineering
services, as needed, to properly respond to the comments.
At this time, it is difficult to anticipate all the permitting issues that may be required by the
regulatory agencies. As a results, we have provided a definite cost estimate for Tasks 1 and 2
only. The cost estimate to complete Tasks 3 and 4 is only approximate and is intended for
budgetary purposes. Once the work of Task 1 and 2 are completed and the final conceptual plans
have been developed and approved, a more precise estimate of costs will be provided.
Attachment A presents a summary of our scope of work and cost estimate. We understand that
City of Winter Garden and City of Ocoee will share the cost of these engineering services. As a
result, we have split the overall cost estimates between the two cities. The following is a
summary of estimated costs, allocated to each city:
3
Task# Estimated Cost Allocated to Estimated Cost Allocated to
City of Winter Garden City of Ocoee
1 $2,375 $2,375
2 $1,091 $1,091
3 $4,000 to $12,500 $4,000 to $12,500
4 $1,000 to $2,500 $1,000 to $2,500
Total $8,466 to $18,466 $8,466 to $18,466
We trust that this proposal is complete and acceptable. If you have any questions or comments,
please do not hesitate to contact our office at 407-330-7763.
