Below is a link to a presentation done by Public Works Director, Mark Dettle, at a recent meeting discussing the use of recycled wastewater. It outlines the history and processes of the City's Award Winning Wastewater Treatment Facility.
We are proud to have won "best in state" from the California Wastewater Environment Association 2013:
Santa Cruz Plant Honored as Best Wastewater Treatment Facility in California. This award acknowledges outstanding achievement in more than 20 categories honoring exceptional California treatment plants, water environment professionals and collection systems. The award combines the results of a review of infrastructure, management practices and compliance records of all entrants into the competition.
The accomplishments listed below were managed by changing out the Facility lighting. These were the challenges:

Wastewater Treatment Facility
Operates and maintains a regional wastewater treatment and disposal facility. Wastewater treatment and ocean outfall disposal are provided for the City of Santa Cruz and the Santa Cruz County Sanitation District (includes Live Oak, Capitola, Soquel and Aptos). Ocean outfall disposal is provided for the City of Scotts Valley.
Wastewater Source Control
Provides inspection, sampling and monitoring of business and industrial establishments to limit discharge of harmful constituents into the sanitary sewer system and storm drain system. Issues wastewater discharge permits to industrial discharges. Issues citations and levies fines for code violations. This program is a requirement of the State of California and U.S. Environmental Protection Agency.
The City of Santa Cruz has been treating sewage at the wastewater treatment facility near Neary Lagoon and disposing of the effluent in the ocean since 1928. Treatment capacity has been expanded several times to accommodate the growth of the city and the addition of flows from the Santa Cruz County Sanitation District. (Photograph of the modern facility below.) The current rated design capacity is 17 MGD (millions of gallons per day) and with an average daily flow of 10 MGD. Design for wet weather flow is 81 MGD.
