2040 WATER MANAGEMENT ACTION PLAN (WATERMAP)
The 2040 WaterMAP is a planning document that provides background information relevant to the water supply
decisions that face the SFPUC. The document will provide the basis for the development of a water supply program
for the 2019 – 2040 planning horizon, helping the SFPUC prioritize future needs and supplies given SFPUC’s ongoing
obligations and new anticipated demands.

2015 URBAN WATER MANAGEMENT PLAN (UWMP)
On June 14, 2016, the SFPUC adopted the 2015 UWMP for the City and County of San Francisco. The purpose of the
UWMP is to assure long-term reliability and efficient use of supplies to meet existing and future demands. The UWMP is
updated every five years and is submitted to the California Department of Water Resources. The 2015 UWMP presents
the latest information on the SFPUC’s retail and wholesale service areas, the Regional Water System and other water
systems operated by the SFPUC, system supplies and demands, water supply reliability, Water Conservation Act of
2009 compliance, water shortage contingency planning, and demand management. This update includes projected
demands and supplies for its retail and wholesale customers over the next 25 years (through 2040) and coincides with
additional planning efforts conducted by the SFPUC, including its 2015 Retail Conservation Plan update.

POTABLE OFFSET INVESTIGATION
The Potable Offset Investigation evaluates the theoretical “maximum achievable” reduction in the Regional Water
System for demand in San Francisco through the use of on-site supplies. The investigation builds on the 2015 UWMP
update for San Francisco by identifying opportunities to offset potable demands (toilet/urinal, clothes washers,
cooling, irrigation) through the expanded use of on-site alternative supplies (including rainwater, seepage water,
graywater, and blackwater) by customer class (single family, multi-family, and non-residential) through 2040.

2015 RETAIL WATER CONSERVATION PLAN
The 2015 Retail Water Conservation Plan provides an overview of the retail water conservation program, the factors
that shaped the program, estimated water savings, and the program’s effect on the overall retail water demand
forecast. The planning horizon for the 2015 Plan spans a 25-year period (from 2015 to 2040) to coincide with
the 2015 UWMP. This plan is produced every five years and acts as a broad guidance document to inform the
development of annual action plans and identify staffing, resource, and budget needs.

NORTH WESTSIDE BASIN SUSTAINABILITY MANAGEMENT PLAN
In March 2015, the SFPUC adopted a Resolution of Intent to Prepare a Groundwater Sustainability Plan for the North
Westside Basin in compliance with the California Sustainable Groundwater Management Act of 2014. A draft plan
was completed in February 2016 and circulated to a technical advisory committee and other interested parties for
review. The overall goal of the Groundwater Sustainability Plan for the North Westside Basin is to assure a long-term,
high quality, local water supply for current and future uses.
