Plant/Process Description:
The San Jose/Santa Clara Water Pollution Control
Plant is one of the largest advanced wastewater
treatment facilities in California. It treats and
cleans the wastewater of over 1,500,000 people
that live and work in the 300-square mile area
encompassing San Jose, Santa Clara, Milpitas,
Campbell, Cupertino, Los Gatos, Saratoga, and
Monte Sereno.
The Water Pollution Control Plant has the
capacity to treat 167,000,000 gallons of
wastewater per day. It is located in Alviso, at
the southernmost tip of the San Francisco Bay.
Originally constructed in 1956, the Plant had the
capacity to treat 36,000,000 gallons of water per
day and only provided primary treatment. In 1964,
the Plant added a secondary treatment process to
its system. In 1979, the Plant upgraded its
wastewater treatment process to an advanced,
tertiary system.
Wastewater from sinks, toilets, and drains inside
homes, businesses and schools in most of Santa
Clara Valley travels through an underground pipe
system, known as the sanitary sewer system,
before it arrives for treatment at the San
Jose/Santa Clara Water Pollution Control Plant.
That journey can take up to 10 hours. About 18
hours later, 99% of the impurities have been
removed through a highly sophisticated treatment
process that simulates the way nature purifies
water, but at a greatly accelerated rate.
Water is a limited resource in the earth's closed
ecosystem. By treating wastewater, cleaner, fresh
water is available for the continued needs of
humans, animals, and plants. Treating wastewater
protects human health from pathogenic bacteria
such as typhoid, cholera, dysentery, polio, and
hepatitis. Wastewater treatment also prevents
oxygen depletion in the water supply and prevents
odors.
Most of the final treated water from the San
Jose/Santa Clara Water Pollution Control Plant is
discharged as fresh water through Artesian Slough
and into South San Francisco Bay. About 10% is
recycled through South Bay Water Recycling
pipelines for landscaping, agricultural
irrigation, and industrial needs around the South
Bay.
