Strengthening OneWaterSF
2018 Initiatives: Matching the Right Resource to the Right Use
Gleneagles Non-Potable Feasibility Study
Of the nine golf courses located in the City of San Francisco, Gleneagles
is the last remaining golf course using potable water for irrigation. Work
under this Initiative will assess the feasibility of utilizing adjacent non-
potable sources for irrigation of the golf course in and around McLaren
Park. Ultimately, the study will be used to determine if the golf course can
use 100% non-potable water for non-potable uses. In 2018, the SFPUC
will complete a small-scale watershed assessment of the golf course site
and its surrounding drainage area to document the potential non-potable
supply and demand for the golf course. This Initiative is the first step in
the planning process; based on the outcomes of the analysis, future work
may include design and construction of a non-potable system to serve
Gleneagles Golf Course.
Southeast Plant Biosolids Demonstration Garden
26
Building upon our work performed under the 2017 biosolids initiative,
this 2018 OneWaterSF Initiative will plan and construct a biosolids
demonstration garden at the Southeast Treatment Plant (SEP). Biosolids
are the nutrient-rich organic material that results from the biological and
physical treatment of wastewater. This material provides multiple benefits
to soil health, including increased water holding capacity and the return
of vital nutrients back to soils. Biosolids also reduce the concentration
of CO 2 in the atmosphere by increasing the amount of carbon able to
be stored in soil. Once constructed, the Southeast Treatment Plant
Biosolids Demonstration Garden will be accessible to SFPUC staff as well
as community members to show the tangible benefits of using biosolids
as a soil amendment. This OneWaterSF Initiative will serve as a visual
representation of the benefits of resource recovery and our ability to
help combat climate change.
