3. Lessons Learned
The SFPUC tested various projects and programs, or initiatives, through a OneWaterSF lens to begin developing a framework and help plan for subsequent years of implementation.
The OneWaterSF Vision and Guiding Principles serve as the foundation for developing and implementing projects and programs that advance OneWaterSF. With the OneWaterSF initiatives, silos are broken down and collaboration is encouraged both within the SFPUC and externally through partnerships with industry, academia and the community. The learning opportunities can also help cities transition to ecologically friendly water, food, energy, and waste systems. The following are highlights of three OneWaterSF accomplishments (OneWaterSF, 2018):
1. Taking Advantage of High-Quality Local Supply
With 85 percent of water supply located over 250 kilometers away; the SFPUC recognized the value of both local water supplies and high quality groundwater located within San Francisco. The San Francisco Groundwater Supply Project reduces dependence on the regional water system and supplements our surface water supplies on a local scale. A second groundwater project, the Regional Groundwater Storage and Recovery Project, will enhance water reliability during periods of drought by providing additional groundwater to San Francisco and neighboring communities when it is needed the most.
2. Re-thinking Rainfall
Rainwater Harvesting from small rain barrels to large cisterns, reduces potable water for irrigation and helps reduce runoff from entering the combined sewer system during storm events. Additionally, the San Francisco Storm Water Management Ordinance, the SFPUC encourages green infrastructure and design into residential and commercial development projects.

3. Reducing Potable Water with Water Recycling
Water is too precious a resource to use just once. Treated effluent from the water treatment and recovery plants offers a new water source for various purposes. The SFPUC is moving ahead with centralized and decentralized water treatment systems to collect wastewater and graywater for non-potable applications such as toilet flushing and irrigation. With growing scarcity of water, and wet years interspersed with extended periods of drought, the SFPUC is advancing the science of purified water with a pilot project that takes treated wastewater from within the SFPUC headquarters and further treats it to meet drinking water standards with advanced technologies.
In the future, expanding the vision of the OneWaterSF, promoting the use of technology and matching the right resources to the right use are the strategic focus areas of this new approach. In spite of the numerous challenges ahead SFPUC is committed to implement new opportunities for utilizing and managing our finite water and energy resources.
The OneWaterSF Vision and Guiding Principles serve as the foundation for developing and implementing projects and programs that advance OneWaterSF. This approach collectively improves communication amongst stakeholders bringing about innovative solution to maximize efficient use of resources. Some highlights of the OneWaterSF accomplishments include taking advantage of local water supply through groundwater projects, rainwater harvesting and water recycling. The learning opportunities from this program can also help cities transition to ecologically friendly water, food, energy, and waste systems.
