The diagram above inspires the question: in a networked web of mains, how do they "meter at the City Gate?"
Background: MWRA presents a water bill to each municipality, say, Medford. Medford pays "one big bill" for all the water that is delivered "to the city gate", including:
  • Metered at residential consumption
  • Metered delivery to other private buildings
  • Unmetered losses (leaks) under the streets
  • Unmetered use in parks, medians, and public buildings
(Medford then bills local residents for water use that contains a little bit of socialism...each metered bill has to charge a slightly higher per-gallon rate in order to cover the city's citywide bill, including municipal uses and municipal leakage)

Does this mean that there is a "Municipal Meter" at each point at which the city draws water out of the Supply Mains and into the "local" pipes?

Why on earth do you think water use in public buildings and parks is unmetered? Even a single water spigot in a median has one of those little remote meter reading things attached to it.

I would tend to assume that municipal buildings and the like are individually metered, with a bit of "pocket A to pocket B" going on where the individual water/sewer assessments is paid out of the individual operating budgets of each department. There probably is some accounting for leakages, meter malfunctions and water theft though.

Could, sure, but do they? Do cities know that all unmetered usage is pure pipe leak?
My understanding is that old “sprinkler park” and fountains were unmetered

Per the Boston Water and Sewer Commission, the City of Boston purchases the water in its network from the MWRA wholesale water network via 29 metered connections to the five Boston distribution networks. So yes, MWRA water is metered (and billed for) at the city network entry points.

Watch your mail: the MWRA has sent out its annual water report(s). If you're in a town served by the MWRA, they send out a general brochure report with a "your town" insert data.
They report on systemwide infrastructure, and then the test results for your town (things like lead, coliform, particulates, etc. as tested at taps in your town)

PDF online: https://www.mwra.com/water/html/awqr.htm

Then the town-by-town test results It is also on their website:

The City of Waltham got notified recently that the MWRA will be installing 9,000 Feet of 36" pipe down Lexington Street from the Lexington Line (Old Friendly's) to Totten Pond Road. Work is expected to be done in 2 phases under 2 separate construction contracts. This first contract is expected to start construction in the Spring of 2022 This new connection will be critical to supplying water to the city when the WASM 3 line is shutdown for rehabilitation starting in 2025.

Is there anywhere to see a regional map of ongoing sewer separation projects? I was curious after the recent releases from storms. This information in general seems extremely scattered and even just the Boston map of projects (the only current-ish one i could find) seems outdated.
