WALTHAM: Waltham buys all of its water from the MWRA through eight master meters and distributes it over 170 miles of main sized four to twenty-four inches, feeding about 14,000 service connections. Lead and copper sampling in September and October 2023 returned a 90th-percentile lead result of 3.83 ppb and copper of 107 ppb, with none of the 20 sampled homes over either action level. The age of the network shows in the maintenance record: in one year the city cleaned and lined 900 feet of six-inch cast iron main and replaced a two-inch iron "main" with 420 feet of two-inch copper.

In 2023 the Water & Sewer Division repaired or replaced 106 water services, repaired 15 water mains and repaired or replaced 29 hydrants; the Engineering Department cleaned and lined 900 feet of 6-inch cast iron water main and replaced 2-inch iron "main" with 420 feet of 2-inch copper, while the MWRA replaced 70 water service connections in the city.
Documents cast iron mains and undersized two-inch iron mains still in service in Waltham — the conditions behind low pressure and rusty-water complaints, and the case for upsizing a private service during a street project.

Backflow device testing and certification in Waltham runs through the city's own division, so a plumbing page can speak accurately about who the testing report goes to.
26.5% of housing in Waltham was built before 1940 (7,128 of 26,898 units, ACS 2019-2023 5-year).
Pre-war stock is where galvanized supply, cast-iron waste and undersized services still turn up.
