Three lakes, and what each one leaves in a tank
A scaling or staining complaint in DeWitt is worth pinning to the supply before anyone diagnoses the appliance. OCWA's source table lists this town on Otisco Lake, Lake Ontario or Skaneateles Lake, one of only two municipalities in Onondaga County given three sources, and the City of Syracuse supplies portions of the town on top of that. Advice borrowed from a neighbor on a different source, or a different purveyor, does not necessarily transfer to your tank.
What water heaters involves
Flush, repair or replace, and how to tell them apart
A rumbling tank that still heats is scale, and it wants a flush and an anode rod check rather than a purchase. White granules that look like powdered soap are the plastic dip tube in a heater built between 1993 and 1996, which is an affordable part and a strong hint that the unit is well past its expected life. Rusty hot water shortly after street work is sediment drawn in from the distribution system, and the fix is to clear it from a cold tap, never by running the hot first, which pulls it into the tank where it settles and stays.
Establish the source before treating the symptom
OCWA reports hardness across its system of 115 to 190 parts per million, about 6 to 11 grains per gallon, which it describes as moderately hard. In a town listed on three sources and served by two purveyors, a change in how the water behaves is worth reporting rather than treating as a fault in your plumbing.
A softener is a comfort decision
OCWA states plainly that softening does not improve the sanitary quality of water. At the hardness published here, an annual flush and an anode rod check do more for tank life than treatment equipment, and cost a great deal less.
The permit and checklist apply throughout the town
Onondaga County requires a plumbing permit before a new water heater is installed, with a residential checklist submitted alongside the application: full port cold inlet valve, relief discharge within 6 inches of the floor, metal connections, thermostat at 120 degrees, expansion tank wherever a pressure reducing valve is present.
Source, hardness and the checklist behind a DeWitt tank
OCWA's 2024 water source table lists the town of DeWitt as receiving water from Otisco Lake, Lake Ontario or Skaneateles Lake, one of only two municipalities in Onondaga County given three sources, the other being the town of Geddes. The City of Syracuse separately reports supplying water to portions of the town of DeWitt under wholesale and service agreements.

OCWA's 2024 Consumer Confidence Report publishes a table of water sources by municipality. In Onondaga County it lists Camillus town, Marcellus town and Skaneateles town as Otisco Lake; Cicero, Clay, Salina and Van Buren towns as Otisco or Lake Ontario; DeWitt and Geddes towns as Otisco, Lake Ontario or Skaneateles; Manlius town as Lake Ontario or Skyridge wells; and among the villages Fayetteville and Manlius as Lake Ontario, Camillus, Marcellus and Solvay as Otisco, and East Syracuse, Liverpool, Minoa and North Syracuse as Otisco or Lake Ontario. Baldwinsville and the City of Syracuse are marked as emergency connections only. In 2024 Otisco Lake supplied 47.2 percent of OCWA's water, Lake Ontario 49.5 percent and Skaneateles Lake 3.2 percent.

OCWA's 2024 Consumer Confidence Report states that the hardness of its water ranges from 115 to 190 parts per million, equal to about 6 to 11 grains per gallon, which it describes as moderately hard, and that the pH runs from 7.1 to 8.7 with alkalinity from 95 to 140 milligrams per liter as calcium carbonate. It adds that softening does not improve the sanitary quality of water, that softeners mostly remove calcium carbonate and stop spotting and scaling, and that softeners may increase water usage because it takes more soft water to rinse away soap.

OCWA states that white particles in the water that look like powdered soap are often the plastic filler tube inside certain water heaters breaking down into granules, that this is most likely with water heaters manufactured between 1993 and 1996, and that the manufacturers report the problem solved, with affordable and easy to install replacements available.

OCWA advises that customers with dirty, discolored or rusty water should run one cold water faucet for 10 to 15 minutes until it clears, and explicitly not run the hot water first, so that discolored water is kept out of the hot water tank. It recommends removing screens, filters or aerators from the faucet being flushed, or flushing a cold bathtub tap instead, and says that after a main break or maintenance work a cold tap should be run for 15 to 30 minutes.

The Onondaga County Residential Water Heater Permit Checklist, revised June 2026, must be completed and submitted with the water heater permit application. It requires a full port valve on the cold water inlet, a temperature and pressure relief valve with the discharge tube piped to within 6 inches of the floor and not reduced in size and with no exposed threaded end, a drain valve on the tank, metal hot and cold lines at least 18 inches long on a gas fired tank, the flue or exhaust fitted and supported with three sheet metal screws and sealed, the temperature set to 120 degrees Fahrenheit, and a drain pan where applicable. Photographs of each item are required, including one showing a placard with the date, the plumber's name, the homeowner and the job address.

Has the water itself changed, or just the hot side?
That distinction decides whether this is a supply question or a tank question.

Water heater questions from DeWitt households
My water changed character and now the kettle scales. Is that the heater?
Check the supply before the appliance. DeWitt is listed by OCWA as receiving water from Otisco Lake, Lake Ontario or Skaneateles Lake, one of only two municipalities in the county with three sources, and the City of Syracuse supplies portions of the town separately. A change in taste, hardness or color can follow a change in which source is feeding your area, and that is worth reporting to your purveyor rather than treating as a plumbing fault. If the water is unchanged and only the hot side is affected, then the tank is the right place to look.
How often should a tank be flushed on DeWitt water?
Annually is the sensible habit at the hardness published here. OCWA rates its water moderately hard at 115 to 190 parts per million, roughly 6 to 11 grains per gallon, and lists DeWitt as taking water from any of three lakes, so the figure at your tap sits somewhere in that band. That is scaling territory, which lays sediment in the bottom of a tank and scales an element. An annual flush with an anode rod check is the cheap half of the repair or replace decision, and it is the maintenance most often skipped because nothing appears to be wrong.
