Where the City's Water Comes From

The City of Maryville Water Department draws surface water from the Little River and treats it with chlorine. Its 2026 report, covering 2025, lists an average chlorine level of 1.72 parts per million.

For a pressure or taste question, the Water Plant is at 865-982-7990. If water is discolored on one street, a call to the plant can say whether the cause is in the system or in your house.

Is It the City's Pipe or Yours?

The City's rules define the customer's water line as the pipe from the meter to the building. A leak after the meter is on the customer's side of that line. We did not find a published rule on who pays for the repair, so ask the City.

Shut off every fixture.Include the ice maker and any irrigation.
Read the meter, wait fifteen minutes, read it again.A moved reading means water is escaping.
Close the house's main valve and read once more.If the meter still moves, the leak is before the house.

See tracing a leak to its location for how to narrow it further.

Digging, Permits and 811

Excavation for a water or sewer line calls for Tennessee 811, which asks for notice at least three and not more than ten working days ahead. Ask any plumber who makes that call.

Long dirt trench with a white pipe at the bottom and a small orange excavator behind it — Any dig starts with the utility locate, and a permit question comes before the machine.

The City requires plumbing inspections on new work: a pressure test at rough-in, before walls or slabs are covered, and a final inspection. Residential inspections are at 865-273-3516.

A Burst or Frozen Pipe

The City's residential code sets a frost depth of twelve inches in its 2018 local modifications. The 2024 edition was not checked, so treat the figure as indicative.

Frost crystals inside a clear pipe section lit by a work light in a framed cavity — Frost inside a pipe means the water has started to freeze, and a split often follows.

Exposed hose bibs, garage lines and crawlspace pipes are the likely freeze points. Know where your main shutoff is before a hard freeze. Handling a broken or frozen pipe lists the first steps.

Frosted outdoor hose bib on a wood wall with a green hose coiled on snow below — A frozen outdoor fixture is a warning to protect the pipe behind it.
