Water Distribution and Wastewater Collection

The town’s primary responsibility for the sewer system is to protect the environment by maintaining unobstructed wastewater flow in the collection system’s main lines. Crews routinely do preventative maintenance and repairs, remove roots and clean sewer lines with pressure washers. 

A non-toxic, non-staining vapor resembling smoke is used in periodic leak testing of the sanitary sewer system.

The town periodically mows and removes trees from utiliy easements and rights-of-way. For more information, see the street maintenance page on this website.

The town will assess the stoppage to determine whether the blockage is on the utility’s side of the sewer line or the homeowner’s side.

The town will clear blockages that occur in the sewer main line or in the sewer service line from the town-maintained cleanout at the edge of the right-of-way to the sewer main.

Homeowners are responsible for blockages in the service line between the town-maintained cleanout at the edge of the right-of-way and the house. If there is no cleanout pipe at the edge of the property, the homeowner is responsible for blockages that occur anywhere in the sewer service line from the house to the main sewer line.

The state building code requires a backwater valve if plumbing fixtures are below the top of the first upstream manhole on the street. A properly operating valve allows flow in one direction, preventing wastewater from entering the building during sewer system maintenance or backups. Consult a builder or plumber to find out if a particular building is required to have a backwater valve.

Fats, oil and grease poured down the drain will collect and stick to plumbing and sewer lines. Over time, lines can become blocked, causing sewer backups or overflows. The following practices can help prevent this:

• Discarding used fats, oil and grease with other garbage.
• Minimizing use of garbage disposals.
• Scraping plates into trash cans.
• Using paper towels to wipe leftover oils and fats from pots and pans.

Additional information can be found in the videos and documents section on this page.

The town tracks and provides an annual report on sewer spills. The most recent summary is available online. Efforts of the sewer maintenance crew have greatly reduced the number and quantity of spills, from 26 in 2000 to 1 in 2014 and 4 in 2015.

Before digging, call 811 to have all underground utility lines located and marked for free.
