Start with your meter and the city's usage data
Before anyone digs, two simple checks narrow things down. First, turn off every fixture, appliance and irrigation zone and watch the meter. If it keeps moving, water is leaving the system somewhere. Second, call Midwest City Utility Customer Service. The city's welcome guide notes that staff can review the water usage on your account to help detect possible leaks, and knowing when the usage changed tells us what to look for.
A sudden jump often points to a fixture failing, like a toilet flapper that stopped sealing. A slow, steady rise over months is more typical of a buried line or a slab leak that has been growing quietly.
Underground water leak detection in older neighborhoods
The buried service line is a common culprit in Midwest City. The city reports that lead was banned in new construction there beginning in 1981, and its service line inventory lists many pre-1981 lines as unknown material because the historical records are incomplete. Public Works is asking owners to help identify the private side of those lines. Older yard lines are often galvanized steel or early copper, and decades in the ground leave them pitted and prone to leaking at joints and fittings.
Wet ground makes these leaks harder to spot. The city monitors five creeks that run through town, including Crutcho, Soldier and Kuhlman Creek, and low ground near them stays damp after rain. A yard that is already soft can hide a leak for months. Acoustic listening, line tracing and pressure testing find the spot without guessing.
City side or yours?
The city's 2025 Water Master Plan reviewed public water work orders and found 543 records tied to pipe condition, including leaking fittings and leaky service saddles where house lines tap into city mains. A leak at the main, the meter or the street belongs to Public Works, which lists 405-739-1383 for after-hours water emergencies. A leak on the house side of the meter is generally the property owner's to fix, and that is the part we find and repair.
