Report
Summary
The purpose of this project is to provide services in support of the Sub-Regional Operating Group (SROG) and the Joint Exercise of Powers Agreement for the 91st Avenue Wastewater Treatment Plant (WWTP) and Tres Rios Wetlands. The 91st Avenue WWTP is located on an approximately 667-acre site just east of 91st Avenue, south of Broadway Road and north of Southern Avenue. The Tres Rios Wetlands is located on an approximately 500-acre site just west of 91st Avenue, south of Broadway Road and north of the Salt River. The operating costs are shared among the SROG cities by measuring the wastewater flow and collecting samples to determine the wastewater strength each city contributes to the 91st Avenue WWTP. Consequently, there are 14 billing meter stations, nine inline meter stations, and five monitoring meter stations within the SROG wastewater conveyance system. The monthly billing and annual year end settlement are based upon the JEPA reporting and related support services. Consulting engineering firms have been performing these support services for over 25 years. A model has been developed which processes pertinent data to calculate the billing amounts. Portions of this model are currently running on the SROG Management Information System website.
Wilson Engineers, LLC’s services include, but are not limited to: weekly flow meter monitoring, monthly flow reports, monthly flow and loading reports, monthly biogas production reports, monthly air permitting reports, quarterly biogas delivery and payment reports, year-end flow and loading reporting, year-end effluent delivery report, audit of meters and sampling stations, future projections (91st Avenue WWTP flow and loading, SROG cities flow and loading, Tres Rios usage, Palo Verde Nuclear Generating Station usage), maintenance of SROG Management Information System website, and special requests by SROG cities.
The 91st Avenue WWTP, Tres Rios Wetlands, associated interceptors (Salt River Outfall and Southern Avenue Interceptor), and metering/sampling stations are owned by SROG and operated by the City of Phoenix.
