Water Quality Notice
To City of Delta Water Consumers:
Your water is completely safe to consume and use for household tasks. There are no known
contaminants in the water. The state has recently changed regulations, which now requires 90% of
backflow devices to be tested across the City on all City owned and commercial/industrial owned
businesses. Unfortunately, we did not receive near enough participation from some of our businesses
across town to reach our compliance ratio. By not meeting the new state requirement, the City is
required to issue a public notice, which happens to give the impression the water is unsafe. The City
assures that the quality and safety of the water is a top priority and will continue to uphold those
standards. The purpose of backflow devices is to keep potentially contaminated water from entering
back into our main water system that can later be passed onto a consumer downstream. Most of the
devices not tested, were irrigation devices that prevent water in the sprinkler systems from getting
back into the main water supply either through backflow or backsiphonage. Unfortunately, we can
not force these businesses to test these devices right now since these devices are not in service due to
seasonal irrigation. By not being in service, there is very little risk of contamination. Just because
these devices were not tested last year does not indicate that they are not properly functioning. The
city continually monitors chlorine levels and performs bi-monthly bacteriological testing to ensure
the safest drinking water possible. Please pass this information along and reach out with any further
questions.

Thank you,
Sincerely,
Water Department
