Water Main & Valve Control
When a main breaks, the only thing that matters is whether the valve closes. Valves that have not been exercised seize, boxes fill with dirt and asphalt, and curb stops disappear under landscaping. Prairie Underground finds them, operates them, and restores them so isolation is possible on the day it is needed.
Every valve exercised is recorded with turn count, direction, condition and box depth, to municipal practice.
Scope of work
- 01 Valve exercising and operation Full open-and-close cycling with turn counts recorded, so seized valves are found before an emergency does.
- 02 Valve box raising and lowering Boxes reset to finished grade after paving, overlay or settlement.
- 03 Box cleaning and repair Removal of dirt, gravel and asphalt from the box, and replacement of broken lids and risers.
- 04 Locating buried valves and curb stops Recovery of assets lost under sod, landscaping or new pavement, then marked and recorded.
- 05 Water main isolation support Shut-down assistance for repairs, tie-ins and planned service interruptions.
- 06 Valve inventory and mapping notes A documented list of what you have, where it is and what condition it is in.
Why it matters
A valve box standing above grade is the first thing a snow-clearing blade finds, and the damage runs down into the valve itself. A sunken box is a trip hazard and a hole that fills with debris until the key no longer seats. Settlement around boxes in parking lots and driving lanes spreads into the surrounding pavement. And a valve that cannot be closed turns a contained repair into a much larger shut-down.
