PLUMBING FIXTURE REPLACEMENT
PROGRAM (PREP)
Planned during the height of the drought to
help accelerate the replacement of old, water-
wasting fixtures, the SFPUC launched the
Plumbing Fixture Replacement Program (PREP),
a toilet and urinal replacement program to help
residences and businesses retrofit some of the
last inefficient fixtures in our retail service area.
During this fiscal year, 757 sites were completed,
representing 1,826 fixtures.
MULTI-FAMILY PREP CASE STUDY:
A 10-unit multi-family property in San
Francisco replaced 11 old, water-guzzling
toilets, 6 shower heads and installed 23
new aerators. These actions helped to
reduce the site’s water use by 28% and
the bill by almost 50%.
WATER-EFFICIENT FIXTURE
IMPROVEMENT PROGRAM (WEFIX)
The
SFPUC
continued
to partner
with
San Francisco Public Works and replaced 79
inefficient toilets and 14 inefficient urinals in 8
City department facilities during this fiscal year.
CLOTHES WASHER REBATES
The SFPUC provided rebates of $100 per washer
for the purchase and installation of qualifying
residential ENERGYSTAR efficient clothes washers
in our retail service areas, and rebates of $500
per washer to customers installing qualifying
coin-operated, high-efficiency, commercial-style
clothes washers. In FY 17-18, 734 rebates were
processed.
RAINWATER HARVESTING
PROGRAM
Rainwater harvesting is the practice of collecting
and using rainwater for landscape irrigation
or toilet flushing. Capturing rainwater at your
home or business reduces drinking water
otherwise needed for irrigation and reduces
the runoff entering our combined sewer system
during storm events. The SFPUC’s Rainwater
Harvesting Program provided residents and
businesses with 29 discounted rain barrels and
11 discounted cisterns.
