New LED street lamp.
Operating 24/7
We continue to invest in and prioritize key projects
in the City of San Francisco to ensure the delivery
of reliable services 24 hours per day, 7 days
per week.
Managing Our Aging Infrastructure
Construction crews continue to upgrade portions of
the Southeast Wastewater Treatment Plant. Built in
1952, much of the facility is operating well beyond its
useful life, and structural elements of the plant are
deteriorating.
Work is in progress on the biosolids digesters—where
solids are managed; the headworks—where flows
first enter the plant; and on a new grit removal
facility—to reduce grit scour and damage to
treatment facilities.
Pipe Repair and Replacement
240
blocks
of pipe repair and
replacement per year
We will continue to increase the water and sewer
pipeline replacement rate over the next three years.
Lighting Up Our City
In 2014, we replaced 119 outdated streetlight fixtures
with new, modern poles and efficient light emitting
diode (LED) lights. Our Wireless Controls Pilot Project
also made progress, allowing us to remotely monitor
and control our streetlights.
We will begin replacement of 18,500 high-pressure
sodium streetlights in 2015. These new LED streetlights
with wireless controls, will improve neighborhood
lighting and reduce maintenance costs.
On average, we generate 1.6 billion kilowatt hours
per year—enough energy to power about
421,053
homes
in San Francisco
for one year
