It buys treated surface water (EPA lists Waterbury Water Department and Watertown Fire District as sellers) and serves 9,972 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 80% of the 5,012 systems serving 3,301–10,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2022–Dec 2024, was 2.0 ppb, below the 15 ppb action level that applied. That’s higher than 67% of similar systems’ latest results.
