Document Description
The purpose of the project is to improve the quality of the effluent from the City's WWTF so that it can be discharged year-round directly into Churn Creek without dilution, consistent with the NPDES Permit requirements. The Project consists of various upgrades to enable the WWTF to meet stricter limitations requirements for ammonia, copper, dichlorobromethane, nitrate, pH, and zinc. The project includes installation of a new effluent discharge pipeline, cascade re-aeration structure, and replacement of the primary discharge point into Churn Creek (Outfall 001). The pre-project maximum daily flow rate for outfall 001, which discharges only in the winter months, is 6.22 cubic feet per second. Post-project, discharge would occur form outfall 001, and the maximum flow rate would be 12.18 cfs. The secondary discharge point into Churn Creek (outfall 002) would be abandoned in place. The pre-project maximum daily flow rate for discharge point 002 is 10.32 cfs, and there would be no post-project discharge. In addition, the spray fields and 400-acre foot reclaimed water reservoir would be taken off line and abandoned in place. With the exception of the effluent pipeline and outfall structure in the riparian area of Churn Creek, all proposed improvements would take place within the existing development footprint of the WWTF.
