Gaps: Our copy of City of Modesto Water Division's list (version directory as fetched (57 listings)), fetched 2026-11-04, has no town or ZIP code for 46 of the 57 companies; no phone for any of the 57 companies (the list prints none for them, or prints a number only one tester of the company gives, or one labelled as a mobile, which we do not republish).
