DPU jurisdiction over water companies

A water corporation or company is: "every person, partnership, association or corporation, other than a municipal corporation, and other than a landlord supplying his tenant, engaged in the distribution and sale of water in the Commonwealth through its pipes or mains" per G.L. c. 165, Section 1.

The DPU regulates privately-owned water companies only.

The DPU does not regulate:

  • City and town-owned water systems, because they are municipal corporations per G.L. c. 165, Section 1. The city or town-owned water system addresses any disputes from a customer.
  • Self-governing water and fire districts created by special acts of the General Court, unless specified in the district's enabling act. For example, some special acts authorize DPU to resolve a price disagreement between two municipalities. These districts do file their rates with DPU for informational purposes per G.L. c. 165, Section 2A.
  • Homeowner associations providing water service, unless they supply water to non-members. In those cases, DPU limits its oversight to only those non-member customers.
