Sewer Commission

Billing inquiries, billing address changes, property ownership changes, or requests for a final bill for a property sale should be directed to the Town Clerk/Tax Collector's office at 603-654-9451 X-1.



Wilton Sewer Department is a participant in the Milford-Wilton Inter-Municipal Wastewater Agreement since 1981. As a co-permittee of the Milford Wastewater Treatment facility, Wilton must operate and maintain its waste disposal system in a manner consistent with standards required by Milford, State and Federal authorities. Wilton pays 14.89% to operate the facility that services the Town of Wilton.

Currently, Wilton Sewer Department’s only source of revenue is its User Fees. Rates are charged to cover costs at a minimum. In preparing for the 2022 budget, Wilton Sewer Commissioners faced several challenges –

  • An increase to Milford’s rates passed on to Wilton Sewer customers for multiple required infrastructure projects.
  • Continue to reserve for emergencies.
  • Necessary improvements to Wilton sewer system infrastructure.

Commissioners believe that the new rate, effective with the billing for Jan-Mar 2022, of $140 per unit per quarter, will allow the department to operate its budget for 2022. The new rate continues to be less than others in the area.

Commissioners are exploring grant opportunities to help support operations and long-range plans and, in the meantime, Wilton Sewer Department is committed to providing outstanding service to its customers at a fair and affordable rate for many years to come.

WSD generally meets on the second Thursday of each month; we invite you to attend these sessions, which are open to the public, to offer input, learn about the 3P's and other ways users can help keeps costs down, or check our progress.

Thank you for your continued support of the Wilton Sewer Department.


Wilton Sewer Commissioners

Chris Carter – Chairman, Kermit Williams, Joanna K. Eckstrom


Please do not flush wipes, even so-called "flushable" ones.

Wipes, including disinfectant ones, paper towels, and anything other than toilet paper clog your sewer or septic pipes, the municipal sewer pipes, pumping stations, and waste-water treatment plants. If you need to use a substitute for toilet paper, put it in a bag and throw it out.

The Wilton Sewer Commission oversees Wilton’s public sewer system and has created an ordinance (see link at right) which sets forth uniform requirements for contributors into the wastewater collection and treatment system for the Town of Wilton, N.H., and enables Wilton to comply with all applicable State and Federal laws. 

The Commission also oversees and sets sewer use fees to fund the work of the department, including Wilton’s participation in the Milford-Wilton Wastewater agreement, in which wastewater services are provided to Wilton by the Milford system.  Sewer use bills are issued 4 times per year on a quarterly basis.  The current USER FEE is $120 per unit per quarter.  Sewer bills that are not paid on a timely basis are subject to a late fee of $5 and 8% interest; a lien may also be placed on your property.

Sewer Commissioners normally meet on the second Thursday of each month at 6:30 PM in the Town Hall Court Room. 

The three Commissioners are elected annually on a rotating basis to serve a 3-year term.
