PUMPING TROUGH PIPELINE

The Pumping Trough Pipeline (PTP) was completed in 1986 to deliver surface water diverted from the Santa Clara River and groundwater pumped from deep wells to growers on about 5,250 acres in the Oxnard Plain and Pleasant Valley. The agricultural irrigation pipeline, a joint project by UWCD, the County of Ventura and the Fox County Groundwater Management Agency, reduces pumping in the over-drafted upper aquifer system.

PUMPING TROUGH PIPELINE:
CONVERSION TO RECYCLED WATER

UWCD is preparing to distribute a new source of water to the PTP system: recycled water. Recycled water is currently produced by the City of Oxnard’s Advanced Water Purification Facility (AWPF) and other agencies surrounding the Oxnard Plain. The AWPF treats municipal wastewater using microfiltration, reverse osmosis, ultra-violet light/hydrogen peroxide disinfection and lime stabilization.

A Title 22 Engineering Report was prepared and submitted to the State Water Resources Control Board Division of Drinking Water in March 2017. The project was conditionally approved in October 2017. These conditions include the removal of cross connections with drinking water systems and compliance with all recycled water use area regulations.

Since the PTP system is not a dual-plumbed system (separate pipeline exclusively for recycled water), all PTP customers will receive the benefit of recycled water once it enters the system. Therefore, the entire system and the areas where water is used must comply with Title 22 requirements (see links below for additional information).

PTP customers’ support is critical to the success of the program.
