Harding Park Recycled Water Project - celebrating the completion of San Francisco's first recycled water project.
The SFPUC partnered with Daly City to construct infrastructure to produce and deliver recycled water to irrigate Harding Park and Fleming Golf Courses. Since October 2012, recycled water produced by the North San Mateo County Sanitation District (NSMCSD), a subsidiary of Daly City, has been used to irrigate 163 acres of public golf course greens. This project received $2.1 million in Proposition 84 grant funding for a portion of the construction costs.
The NSMCSD constructed facilities at its wastewater treatment plant to produce recycled water. The plant also provides tertiary recycled water for irrigation purposes at the Lake Merced Golf Club, Olympic Club, and San Francisco Golf Club, as well as other landscaped areas in Daly City.
Expanding Distribution of Recycled Water
These recycled water customers use less than 1 million gallons of recycled water per day on average. The plant has the capacity to produce up to 2.8 million gallons of recycled water per day. As a result, the NSMCSD has recycled water available to irrigate Harding Park and Fleming Golf Courses, while still meeting the needs of its current recycled water customers.
The project includes:
- Distribution: A new pump station at the Harding Park Maintenance Yard, and approximately 4,800 feet of 18-inch distribution pipeline along Lake Merced Boulevard.
- Storage: A new 700,000 gallon underground recycled water storage tank at the Harding Park Maintenance Yard.
- Back-up Connection: A back-up connection to the SFPUC potable water distribution system.
The use of recycled water to irrigate Harding Park and Fleming Golf Courses reduces the San Francisco Regional Water System’s dependency on a single source of water, decreases demand on surface water, provides a drought-resistant water source, and decreases wastewater discharges to the Pacific Ocean.
