Subject: Notification of the Emergency Repair to the Digester Air Line t the Wastewater
Treatment Plant
The Wastewater Treatment Plant uses aerobic digestion to stabilize and reduce the amount of
activated sludge generated by the treatment process. Centrifugal blowers create large volumes of
compressed air that is utilized by aerobic bacteria in the plants digester to achieve the stabilization
and reduction of this sludge. Approximately 160 feet of buried 16" diameter ductile iron pipe transports
this compressed air from the blowers to the digester process.
On January 21st, 2017 at approximately 5:00pm, the buried 16" ductile iron pipe transporting the
compressed air experienced a large scale failure requiring the aerobic digestion process to be shut
down. The age of the pipe, combined with the extremely corrosive environment created by the
temperature and moisture content of the air ultimately caused several feet of the line to materially fail.
Close examination of the remaining airline determined that the entire buried portion was also
extremely corroded and could no longer be used requiring a complete replacement. The new piping
was installed above ground and supported by concrete pedestals, which provides easier access
control, and lengthens the life of the pipe thermally.
The Wastewater Treatment Plant currently presses 105,000 gallons of digested liquid sludge per week
to maintain the optimum MLSS levels in the wastewater treatment plant. Without aeration of the
sludge in the digester, the sludge would settle out and solids buildup would clog the system.
Additionally, our press would not be able to press the un-aerated/undigested sludge after a short time
due to undigested impurities that would render the press belt unusable.
• Weekly disposal cost of aerated, digested dried/pressed sludge: $2,400.00
• Weekly disposal cost of raw, undigested/un-aerated sludge: $16,800.00.
Due to the critical nature of the aerobic digestion process and the financial impact of hauling wet
sludge compared to dry sludge, staff solicited quotes from existing City approved contractors for the
labor and miscellaneous material need to make the emergency repair of the airline. The following
quotations were received:
1. SanPik-$39,950.00
2. Schuller Contractors Incorporated - $48,098.00
3. CFE, Corporation - $70,817.00
4. RMS Constructors Group - $168.000.00
5. Barracuda Contractors— Declined to quote
SanPik, the lowest bidder and already mobilized due to working on the downtown sewer project, was
awarded the work.
To expedite the pipeline repair, the City obtained the pipe material and fittings directly from HD Supply
at a cost of$17,508.00.
