Current & Upcoming Projects

Tustin Water Services is committed to providing reliable, high-quality water to our customers while also maintaining adequate storage for emergency needs. To achieve this, we carefully plan and invest in capital improvement projects. Below is a list of our current and recently completed water system improvements.

Recent Projects 

Main Street PFAS Treatment Facility

Portions of Orange County's groundwater supply have been impacted by per- and polyfluoroalkyl substances (PFAS), chemicals that were once widely used in consumer products and are now found throughout the environment.

Since 2019,  Orange County Water District (OCWD) has taken the lead in addressing PFAS, in partnership with its 19 cities and retail water districts, to remove them from the groundwater basin, which supplies up to 85% of the water to 2.5 million people in north and central Orange County. 

To help protect local water, OCWD partnered with the City of Tustin  to built a new PFAS treatment facility at Main Street and Prospect Avenue to remove PFAS from four (4) wells in Tustin.  Construction began in  March 2023 and was completed in May 2025. The new treatment system, implemented at the existing Main Street Water Treatment Plant, uses ion exchange technology to treat up to 6,400 gallons of groundwater per minute. The centralized plant is fed by four (4) offsite wells connected through approximately 2.5 miles of conveyance pipeline. 

This major investment in Tustin’s water quality was made possible with the support of:

  • $10 million grant from the State Water Resources Control Board through the Bipartisan Infrastructure Law
  • $5 million Community Grant from the U.S. Environmental Protection Agency

Together, these efforts ensure cleaner, safer water for Tustin residents today and for generations to come.Tustin Water Treatment-19

Beneta Well No. 2

Tustin Water Service received a $1.5M grant through the Santa Ana Watershed Project Authority and Orange County Water District to drill a new potable water well within the Tustin Water Service area. The existing Beneta Well site (removed from service in 2010) was selected as the new well site location. Construction began in 2022 and was completed in May 2025. \The Beneta Well is now operational and producing  up to 1500 gallons per minute of new groundwater supply for Tustin Water Service customers. Beneta Well pumps to the Main Street Treatment Facility for PFAS removal prior to distribution into the water system.  

Simon Ranch Reservoir and Booster Pump Station Replacement

Simon Ranch Reservoir is located at the intersection of Outlook Lane and Valhalla Drive in North Tustin. 

Planning efforts began in 2006 when an evaluation of the reservoir indicated that the facility’s useful life was coming to an end.  

The City Council approved the construction contract with Pacific Hydrotec Corp on February 18, 2020 and construction was completed in June 2022.
