Water & Wastewater
Oxford County owns and is responsible for the management, maintenance, and long-term capital planning for the County's water and wastewater systems.
Oxford County operates all water treatment facilities and wastewater treatment plants. The City of Woodstock and the Town of Tillsonburg operate portions of their water distribution and wastewater collection systems. Oxford County operates and maintains the water distribution and wastewater collection system in the remaining Area Municipalities and select portions of the City of Woodstock and Town of Tillsonburg systems.

What's new
With 100% groundwater as Oxford County’s drinking water source, mineral build-up in the water distribution system is common. Regular watermain flushing helps maintain drinking water quality by removing build-up and mineral deposits in the distribution system. This is done by forcing water through watermains at high speed and discharging it through hydrants and blow-offs. The fast-moving water washes away any sediment.
Fall watermain flushing begins September 22 and runs until November 7, 2025. Find the fall flushing dates for your community here.
Oxford County has introduced an annual newsletter, “Waterline,” to replace other water and wastewater notices mailed throughout the year, including watermain flushing and outdoor watering notices. Residents can expect to receive the newsletter in the mail in March and are encouraged to keep it handy for future reference.
The 2024 Annual Water System Performance Summary Reports are now online. Oxford County treated and supplied approximately 10.9 million cubic metres of clean, safe and reliable drinking water to 21 communities through 17 municipal drinking water systems last year.
At the time of the February 26 report to County Council, results were available for nine of Oxford’s municipal drinking water system inspections completed by Ontario’s Ministry of the Environment, Conservation and Parks. Eight systems received a 100% inspection rating (Beachville, Brownsville, Embro, Hickson, Lakeside, Mount Elgin, Tavistock and Thamesford) and one system received a 92% rating (Innerkip). The remaining system inspection report ratings were either not available at the time of the Council report or the inspection had not yet been carried out.
