Lexington's city water is chlorinated Lake Thom-A-Lex water, and the 2025 report doesn't publish hardness, so test before buying a softener. In a city where about two-thirds of homes predate 1980, rusty or gritty water is more often an old-pipe problem than a water-chemistry one.

Lexington's water and its older houses
The City of Lexington runs its own water system, drawing from Lake Thom-A-Lex, which it shares with Thomasville, and treating it at two plants off Old Greensboro Road near Business I-85. Those plants date to 1922 and 1967. The 2025 water quality report lists chlorine as the disinfectant at a running annual average of 0.79 ppm, reports no violations, and shows lead at 0 ppb at the 90th percentile in October 2024 sampling. It doesn't report hardness, sodium or pH.
The homes matter as much as the water. The median Lexington house was built in 1969, about 68% predate 1980, and roughly 14% predate 1940. Houses in the mill village and older residential districts can still have galvanized supply pipe, which rusts from the inside out. If you want to know what the City's records show for your service line, its inventory is posted online and kept at City Centre, 200 N. State St. The 2025 report also notes that residents share responsibility for plumbing on their side.
Matching the problem to the equipment
| What you notice | Equipment that addresses it | Lexington note |
|---|---|---|
| Chlorine taste or smell | Activated carbon at one tap or for the whole house | The City uses chlorine, which carbon removes readily |
| Rust tint or flakes | Sediment filter for now, repiping for good | Typical of pre-1980 houses with galvanized lines |
| White crust on fixtures | Softener, but only if testing confirms hardness | No hardness figure is published |
| Wanting very clean drinking water | Reverse osmosis under the kitchen sink | Needs a drain tie-in and cabinet space |
Signs worth having checked
- Brownish water from the first cold draw of the morning
- Aerators clogging with orange grit
- Rusty water from the hot side only
- Chalky crust on faucets or showerheads
- A softener that goes through salt with no visible difference
Timing and sequence
Discoloration that shows up only in hot water usually points at the water heater's tank or anode rather than the supply. Rust that comes through cold taps after the house sits overnight points at the pipes. If water turns cloudy right after City main work, run a cold tap for a few minutes before deciding you need equipment. In an older house, sort out the piping before buying new fixtures, so fresh valves aren't loaded with scale on day one. Ask the plumber whether the work needs a permit; Lexington takes applications through its online Permit Portal.
