01Private plumbing discussion
Call 877-702-1610 for a private fixture, pipe, drain, heater, or estimate question. Before sharing an address, ask who answered and confirm Hingham coverage, the legal contracting entity, license, insurance, visit fee, availability, recording, and terms.
02Water system or account
Use the live Weir River Water or HMLP path for public-supply, meter, account, billing, service, water-quality, or utility equipment questions. The transition page says HMLP handles billing and customer support beginning July 1, 2026.
03Town review
Use Hingham's Building Department, Sewer Department, or Board of Health for the address-specific permit, inspection, district, connection, Title 5, or record question each office controls.
04Immediate danger
For gas odor inside, leave rapidly and call 911 from outside under Massachusetts guidance. Use emergency services for immediate danger and do not call the referral number first.
