Cambridge is one of the few communities in the region that treats its own drinking water rather than buying it from the MWRA, drawing from the Hobbs Brook, Stony Brook and Fresh Pond reservoir system and purifying it at the Walter J. Sullivan Water Treatment Plant before it reaches Cambridge taps by gravity from the Payson Park Reservoir. That means any water-quality or fixture question here has to be answered against Cambridge's own water testing, not a regional average. Plumbing and gas permits for the city are issued and inspected separately, through Cambridge's Inspectional Services Department at 831 Massachusetts Avenue.

The MWRA lists Cambridge with the service string "Water (emergency backup only), Sewer" — meaning Cambridge is an MWRA sewer community but takes MWRA water only as emergency backup.
CRITICAL SUPPRESSION RULE: because Cambridge normally drinks its own treated water rather than MWRA water, the MWRA system hardness figure (approximately 16 mg/L / 1 grain per gallon) and treated pH (approximately 9.0-9.5) must NEVER be published on a Cambridge page. This is the exact figure competitors' generated pages fabricate, and applying it here would be wrong on the facts, not merely generic.
Cambridge operates its own drinking water supply: three in-series reservoirs — Hobbs Brook, Stony Brook and Fresh Pond — draining a 24 square mile basin in Lexington, Lincoln, Waltham and Weston. Fresh Pond raw water is purified at the Walter J. Sullivan Water Treatment Plant, then pumped to Payson Park Reservoir, a covered storage facility in Belmont, from which it flows by gravity into the Cambridge distribution system. The city typically requires 12 to 13 million gallons per day.
Cambridge is one of very few communities in this footprint that treats its own water rather than buying MWRA water. Any water-quality, filtration or fixture-scaling claim on a Cambridge page must be sourced to the Cambridge Water Department's own reporting, never to MWRA system figures.
Cambridge's Inspectional Services Department (ISD), at 831 Massachusetts Avenue, is "staffed with 28 inspectors and support personnel" and administers "the State Building, Plumbing and Gas, Electrical, and Mechanical Codes," the Massachusetts Access Board Regulations (521 CMR) and provisions of the State Sanitary Code. ISD publishes separate online permitting and fee schedules for Building, Electrical-Wiring, and Plumbing and Gas.
Identifies the city-varying half of permit authority for Cambridge — the specific office, its address and its separate plumbing-and-gas fee schedule. The statewide 248 CMR invariant belongs once on the trade hub, not on this page.
47.3% of housing in Cambridge was built before 1940 (25,831 of 54,612 units, ACS 2019-2023 5-year).
Pre-war stock is where galvanized supply, cast-iron waste and undersized services still turn up.
