History of Recycled Water
in Walnut Valley Water District

Recycled Water System--Inception
With
the completion of the District's original recycled water
system in 1986, recycled water from the Pomona Reclamation Plant
began to irrigate the landscaped areas of schools, parks, and other
private and public entities.
The District's original recycled water
system was completed at a cost of $8.5 million. The system included:
- 17 miles of pipeline (20-inch diameter to 4-inch diameter)
- 2 million gallon storage tank
- Recycled Pump Station
- Main pump capacity of 3,500 gallons per minute
- Booster pump capacity of 500 gallons per minute
- 21 customers serving 340 acres of land
Recycled Water System--Expansion 1997-2003
Over
the years the District has continued to expand the use of this "drought-proof
water supply" which is not subject to the restrictions that
may be imposed on drinking water imported from distant sources.
The District's first recycled well, which on average produces 330
gallons per minute, was completed
in 1989 to pump groundwater
from the underlying basin. In
1992, the District doubled its storage capacity with the addition
of a 2 million gallon storage tank that
was constructed next to the existing tank. The District's second
recycled well was completed in 2003, which provides an additional supply
source that on average produces 155 gallons per minute.
Recycled Water System--Current
Today the District's recycled water system
has a current value of $13 million and consists of the following:
- 31.5 miles of pipeline (20-inch diameter to 4-inch diameter)
- 2 storage tanks with a combined capacity of 4 million
gallons
- Recycled Pump Station
- Main pump capacity of 3,500 gallons per minute
- Booster pump capacity of 500 gallons per minute
- 227 metered connections serving 600 acres
of land
- 3 wells with a combined average production of nearly 1,000 gallons
per minute
