Should treated wastewater in Hercules and Pinole be used for productive purposes, like irrigation? That’s the subject of a new survey being distributed by the City of Pinole. 

The Pinole-Hercules Wastewater Treatment Plant (WWTP) at 11 Tennent Ave. treats all of the residential and commercial wastewater generated in Hercules and most of the wastewater generated in Pinole. The plant “removes solids from the wastewater and sanitizes the water, then discharges the treated wastewater into the Bay through a pipe in Rodeo,” according to City of Pinole officials.

Officials are exploring the possibility of using treated wastewater for other purposes like recharging underground aquifers, providing irrigation water in specific circumstances and for industrial purposes.

“The City is hiring an expert to assess the technical and financial feasibility of reusing the treated wastewater, and aims to learn what opportunities exist to cost effectively reuse the water generated by the Plant that are feasible in the current regulatory and contractual environment,” officials said.
