Where are the sewage
treatment facilities in your community?
The San
Francisco Utilities Commission (SFPUC) owns and operates San Francisco’s combined
sewer system, which collects and treats both sewage and stormwater runoff.
There are 3 sewer system treatment facilities in San Francisco. The first
facility, North Point Wet-Weather Facility (NPF), was built in 1951 and is located
at Bay Street and Embarcadero. This facility treats wastewater only during wet
weather and has a capacity of 150 million gallons per day (MGD) during
rainstorms. The second facility, Southeast Treatment Plant (SEP), was built in
1952 and is located on Phelps Street near Third and Evans streets in the
Bayview District. This is the largest all-weather facility treating 80% of the
City’s flows and treats on average 60 MGD of wastewater and up to 250 MGD
during rain storms. The third facility is Oceanside Treatment Plant, which was
built in 1993 and is located is located off the Great Highway between Lake
Merced and the San Francisco Zoo. This facility treats 20% of the City’s flows
and on average treats 15 MGD of wastewater and up to 175 MGD during rainstorms.
San Francisco recognizes that we are dealing with aging
infrastructure and that there are portions of our combined sewer systems that are
over 100 years old. The Sewer System Improvement Program (SSIP) is a 20-year
citywide investment to upgrade our aging sewer infrastructure to ensure
reliable, sustainable and seismically safe sewer system now and for generations
to come.
Hi Marisa,
ReplyDeleteI live in Menlo Park, which does not have it's own sewage treatment facility. However, I did a google search to investigate whether there would be plans to build one -- there's definitely been some talk about it, but no news about actual building plants yet.

Hi Marisa,
ReplyDeleteI live in Half Moon Bay and we have a small treatment plant. It does provide water to towns from south of Pacifica to Half Moon Bay, but is not as big as the San Francisco one. Thank you for sharing what you found out about your treatment plant. I am glad that SF recognizes the aging infrastructure and that a plan has been put in place to address this issue.
Great post!

Hello Marisa,
ReplyDeleteI find it very surprising to see how many sewage facilities are in San Francisco. It also brings up questions as to whether SF has been able to keep up with the waste run-off with their current facilities. I can only imagine that the upgrades will become bigger to accommodate the increase of waste produced by a growing population.
