Annual Drinking Water Quality Report

|
The City of Indio is please to provide
you with the year 2000 Water Quality Report. The City prepared this
report to inform you about water we have delivered to you over the past
year. The Safe Drinking Water Act of 1974 established uniform nationwide
standards for the quality of drinking water. In 1986 the Act was amended
to include more stringent standards and also to increase the number of
contaminants that are regulated. The California State Department of
Health Services has adopted, in some instances, even stricter standards
The City uses federal and state certified laboratories for
bacteriological, physical, chemical and radiological water analysis.
Samples from throughout the system are collected weekly and submitted
for testing by specially trained water personnel to ensure the safety of
the water supply and compliance with all applicable standards.
A total of 13 sampling stations are located throughout the City of Indio
and surrounding Riverside County locations at wells, on water
distribution lines, at booster stations, and near reservoirs. The City
of Indio water system produce 5.22 billion gallons of water (697.97
millions cubic feet) during calendar year 2000. The water was produced
from thirteen underground water wells, with all wells pumping into four
above ground reservoirs. The water from reservoir storage is pumped into
the system.
Electric and natural gas engines power the distribution system. Pressure
is maintained in the distribution system by pressure-control variable
speed motors. Sodium hypochlorite solution is injected into the water
supply at a residual of 1 PPM (parts per million) as a bactericide. No
other treatment of City of Indio water occurs.
The highest volume of water pumped in one day during 2000 was 22.84
million gallons (3.05 million cubic feet) on August 25th. the water
system began the year with 9,912 active customer service accounts and
ended with 12,117 customer service accounts. |
