Water Quality Reports

...it's better on tap!

Moulton Niguel Water District is committed to testing, protecting, and delivering high-quality water to our 170,000 customers, and we are pleased to report that the drinking water provided to your homes, schools, and businesses meets or exceeds the standards required by state and federal regulatory agencies.

The annual water quality and consumer confidence reports provide information on the sources of our water supply, information about your drinking water, and water quality results for the previous calendar year. Remember, the next time you reach for a refreshing cool glass of water… it’s better on tap!
