| Harding Park Golf Course |
In 2004, the North San Mateo County Sanitation District (NSMCSD), a subsidiary of Daly City, constructed facilities at its wastewater treatment plant to produce recycled water. The plant currently provides recycled water that is used for irrigation purposes at the Lake Merced Golf Club, the Olympic Club, and the San Francisco Golf Club, as well as other landscaped areas in Daly City. 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 for its current recycled water customers.
Daly City and the San Francisco Public Utilities Commission (SFPUC) are proposing to expand the NSMCSD’s recycled water distribution system in order to provide recycled water for irrigation purposes to the Harding Park and Fleming Golf Courses. Recycled water would replace potable water from the SFPUC’s Regional Water System currently being used for irrigation.

The proposed project facilities would include:
- Distribution Facilities: The project would require 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 Reservoir: The project would require construction of a new 700,000 gallon underground recycled water storage tank at Harding Park Maintenance Yard.
- Back-up Connection: The project would require construction of a back-up connection to SFPUC potable water distribution system.
Purpose and Need
San Francisco residents enjoy some of the nation’s highest-quality drinking water. The San Francisco Public Utilities Commission’s (SFPUC) Regional Water System delivers pristine Sierra snowmelt from the Hetch Hetchy Reservoir, and water from protected local reservoirs, directly to our customer’s taps. Diversifying San Francisco’s water supply portfolio, through the increased use of available local water sources such as recycled water and groundwater, will ensure that a reliable water supply is available in the event of a major earthquake, drought, or a decline in the snow pack. Developing recycled water for non-potable uses will help ensure that our water supply portfolio is managed to provide a reliable, high-quality supply for drinking water.
The SFPUC proposes to replace drinking water used for irrigation of Harding Park and Fleming Golf Courses with recycled water supplied by the North San Mateo Sanitation District (NSMSD), a subsidiary of Daly City. The NSMCSD constructed facilities at its wastewater treatment plant to produce recycled water. The plant currently provides highly-treated tertiary recycled water for irrigation purposes at the Lake Merced Golf Club, the Olympic Club, and the San Francisco Golf Club, as well as other landscaped areas in Daly City.
Use of recycled water to irrigate Harding Park and Fleming Golf Courses would reduce the San Francisco Regional Water System’s dependency on a single source of water, decrease demand on surface water, provide a drought-proof water source, and decrease wastewater discharges to the Pacific Ocean.
