Plumbing in DeWitt, Where the Water Bill Names the Rules
In DeWitt the first question is not what is wrong with the pipe, it is who supplies it, because that decides who owns what at your curb. DeWitt is one of only two municipalities in Onondaga County listed on three water sources, and the City of Syracuse supplies parts of the town on top of that.

Why a DeWitt address needs its purveyor confirmed first
DeWitt is the hardest town in this metro to generalize about. OCWA's own source table lists it as receiving Otisco Lake, Lake Ontario or Skaneateles Lake water, one of only two municipalities in the county given three sources, and the City of Syracuse separately reports supplying individual customers and portions of the town under wholesale and service agreements. So one street can be on a different lake and a different purveyor from the next, and the two purveyors do not draw the ownership line in the same words. OCWA owns the pipe to the shutoff at the property line, and everything from the outlet side of that valve inward is yours. The City divides a service into three parts with the curb box as the boundary and the meter as City property. Reading the name at the top of the bill is the step that tells you which rule governs your curb before anyone quotes. The pipe evidence here is thin in both directions: 2,036 lines recorded under DeWitt with 1,974 of them unknown, and 878 under Town of Dewitt with one lead and two galvanized. Against a median build year of 1963 and 18.7 percent of homes built before 1940, that argues for having the material identified at the meter rather than assuming anything, in either direction.

The City of Syracuse Water Department states that it provides retail water service to the entire City of Syracuse and, through wholesale and other service agreements, also supplies water to individual customers and portions of the towns of DeWitt, Onondaga, Geddes, Camillus and Salina, and supplies source water to the villages of Skaneateles, Jordan and Elbridge. Because the north side of the city is connected to a system supplied by OCWA, that area may receive Lake Ontario water from time to time.

Onondaga County Water Authority states that ownership of a water service line is shared: OCWA owns the portion from the water main to the shutoff valve at the property line, and the customer is responsible for the portion from the outlet side of that shutoff valve to the water meter or main shutoff valve inside the home, plus all internal plumbing and fixtures.
