Kraft Assistant City Attorney Contract Amendment No. 1 Page 2 of 2 - 39b - • Res 90-345 AMENDMENT N0. 1 EXHIBIT A DESCRIPTION OF PROJECT FOk WASTEWATER TREATMENT PLANT IMPROVEMENTS SEPTEMBER 14, 1990 � The Oshkosh Wastewater Treatment Plant-has an extensive flow metering and sampling program that is designed to monitor the performance of the system. Under this current arrangement, the plant flows and loadings are measured on the discharge of the raw sewage pumps after the flows and loadings from the sidestreams have combined with the influent. Although this arrangement provides information that can be :rsed to evaluate the performance of the process units, it does not allow the � true characteristics of the plant influent or sidestream to be determined. In the past, this has not presented a problem. The wastewater treatment p1Ant has had sufficient capacity and there was no need to differentiate between the characteristics of the influent and plant loadings. Under current conditions, however, the need to differentiate between influent and plant flows and loadings is becoming essential. The true influent characteristics are needed to evaluate the significance of toxic substances discharged to the wastewater treatment plant and to properly allocate operating costs; and the sidestream characteristics are needed to properly evaluate the cost of existing and future solids handling alternativese The recommended plan for sidestream monitoring at the Oshkosh Wastewater Treatment Plant is to sample the influent flow, meter the sidestream flow and calculate all other unknowns using the data from the existing plant flow metering and sampling system. Influent sampling and sidestream flow metering will provide the most accurate results because the least accurate variables, influent flow and sidestrearo concentrati�on will not be used. Influent sampling and sidestream flow metering will provide data on the true influent characteristics as required by the WPAES permit and allow calculation of the sidestream loadings. Influent sampling and sidestream flow metering will minimize costs for sampling, testing, and flow metering; will minimize the capital cost for constructing new facilities, and will use the existing flow �etering and sampling facilities to the maximum extente Influent sampling would be accomplished by installing a submersible pump in the influent channel to the comminutors that would discharge to a sampler located in the central tunnel just south of the raw sewage discharge header. The sampler would be a Chicago Pump Type CR flow proportional, refrigerated unit that would match the existing samplers at the plant. The plant computer system would calculate influent flo� and send a signal to activate the sampler Qn � flow proportion�l basis, Contract Amendment No. 1 Exhibit A Page 1 of 2 - 39c - Res 90-345 Sidestream flow metering would be accomplished by installing a flow meter on the discharge sewer in the influent wet well. The most suitable device would be a flow nozzle or pipe mounted Palmer Bowlus flume. Either device would be mounted on an extension of the sidestream discharge sewer pipe. The flow nozzle or flume would be sized to prevent the �sidestream discharge sewer pipe from surcharging. The straight-through flow characteristics would minimize problems with solids buildupso The sidestream flow meter would be sized for a maximum flowrate of 2800 gpm which requires an 18-inch flow nozzle or Palmer Bowlus flume. A non-contact ultrasonic level transmitter would be used to eliminate fouling probleros associated with subsonic or bubbler type systems. The flow signal would be transmitted to the plant computer, where it would be recorded, totalized, and used to calculate the influent flow. Ideally, the discharge from the flow meter would be arranged such that it could be directed to either of the two compartments of the raw sewage pumps �et welle The submersible sample pump, flowmeter and all associated electrical and instrumentation wiring that would be located in the wet well would be of explosion proof type construction. The s�mpler and other items not located in the wet well would be of standard design. Piping from the sample pump to the sampler would be PVC and would be sized to provide a minimum velocity of 2 feet per second. The estimated construction cost of the sidestream monitoring facilities is $50,000. The work would be perforroed by a Contractor with assistance from the staff of the WWTP as needed. The work is of such a nature that it would not be necessary to t�ke any plant units out of service during constructione The project schedule calls for the design to be finalized in October of 1990. Bids fos the project would be taken in November and construction would take place during January, February, and March of 1991. St�rt-up of facilities would be completed by March 31, 1991e Contract Amendment No. 1 Exhibit A Page 2 of 2 - 3 9 d - • � Res 90-345 AMENDMENT N0. 1 EXHIBIT � SCOPE OF ENGINEERING SERVICES FOR WASTEWATER TREATMENT PLANT IMPftOVEMENTS SEPTEMBER 14, 1990 ' The work to be performed is divided into four major parts.
