Analysis
Espey Consultants is the firm that master planned the City's wastewater system and as such has a hydraulic model of the system. They are in the best position to perform necessary support services such as: 1) reviewing wastewater flows using TRA data and advising the City on anomalies in data as applied to the city's wastewater service areas and expected wastewater flows; 2) assisting in completing the mothballed South Sector Lift Station which we constructed before development stopped and has never been used; 3) providing analysis of proposed land development projects in the city to advise on impacts to the City's wastewater collection system; 4) assisting in response to active sanitary sewer overflows occurring in the city's wastewater system that do not involve simple stoppages but are related to capacity and inflitration/inflow issues; and 5) updating the city's design standards for wastewater design when improvements to the system are considered.
This particular contract approved by the City Council June 7, 2016 (16-5657) specifically addresses the installation of check meters to continue the field investigation/accuracy of TRA billing meters as well as other support services described above.
Change Order/Amendment No. 1 in the amount of $72,768 approved by City Council October 11, 2016 (16-6049) represented the proposed change in scope for the analysis of data on two week intervals, extended temporary flow metering period until 11/3/16 and additional general support in reviewing flow data.
Change Order/Amendment No. 2 in the amount of $145,908 approved by City Council extended the metering period from November 2016 to end of February 2017 but additionally, where flow differences have been found, installed additional temporary wastewater flow meters upstream of two of the TRA meters where downstream temporary meters have detected flow measurement differences. Each of the phases of contract changes has also included the funding of services for analysis of the flow data and reporting to City management as this amendment does.
The Current Change Order/Amendment No. 3 in the amount of $105,675 will provide additional temporary metering and development of three metering meetings with TRA, the City and jointly with TRA and the City to address the final limits of data needed and the information that can be used to resolve metered flow differences.

Funding for change order/amendment No.3, in the amount of $105,675 is available by approving an ordinance transferring and appropriating from the unobligated fund balance in the Wastewater Capital Projects Fund (500692), WO #01612703 (TRA Wastewater Support) 61039 (Professional Services).
