The annual report says Wilton Water & Sewer Authority met state drinking-water standards in 2025 and reported no maximum contaminant level violations.
Wilton Water & Sewer Authority has posted its Annual Drinking Water Quality Report for 2025, and the report says the system met state health standards last year with no maximum contaminant level violations.
As of Friday, June 5, the Wilton Water & Sewer Authority’s website links a new Annual Drinking Water Quality Report covering calendar year 2025.
According to the report, WWSA served about 9,743 people through 3,897 service connections. The authority says it produced 437,326,000 gallons of water in 2025, with an average of about 1.12 million gallons a day and a peak single-day demand of 2.289 million gallons.
The report says customers were billed for 386,215,000 gallons, or 95.77% of total production. It attributes the difference to firefighting use, system flushing, water-meter error, and leaks.
The document also gives a few system details that are easy to miss elsewhere on the site. It says the Fairway plant wells remain out of service because of high iron levels. It also says the only fluoridated water in Wilton is water purchased from Saratoga Springs for the Home Depot Plaza and Price Chopper Plaza area on Route 50.
This is the authority’s required annual consumer-confidence report. For water customers, it is one of the clearest single public documents showing how much water the system produced, how many people it served, and whether state limits were exceeded.
No new board action is required for the report itself, but residents who want more detail can review the full document on the WWSA site.
