The Path to Your Tap Isn’t
a Straight Line
From the Sierra Mountains and the Colorado River to
the ground beneath our feet here in Los Angeles, the
water that fuels our city comes from diverse sources.
LADWP takes wastewater from
Los Angeles homes and
businesses and purifies it for
reuse in irrigation and
groundwater replenishment.
Underneath the city are natural aquifers
that LADWP protects and replenishes,
storing water for future use.
When it rains where does all the water
go? This water can be captured into the
groundwater, pumped and used as
another source of water for the region.
While LADWP increases investments in
more reliable, local supplies, we’re
augmenting our supply with purchased,
imported water from the Colorado River
and State Water Project.

Built in 1913, the LA Aqueduct was at
the time the largest water infrastructure
project in the world. Now more than a
century later, the aqueduct still runs 233
miles north of Los Angeles carrying
fresh runoff from the Eastern Sierra to
the L.A. Basin.
