Water Line Repair in Phoenix, AZ

Who owns which part

The City of Phoenix Water Services Department runs the mains under the street. The City says property owners are responsible for the water and sewer lines on their property up to the City's main lines, and condo owners should check with their HOA. The City page does not spell out the exact dividing point at the meter, so if the leak is near the meter box, call the City at 602-261-8000 and let them look first.

Signs the main line is leaking

• A wet or green patch in the yard during a dry stretch
• Water seeping through gravel or pavers between the meter and the house
• Pressure that drops for no clear reason
• The meter leak dial spinning while the house shutoff is closed
• Cracks in a driveway or walkway that stay damp

What material is your line?

The City keeps a service line inventory that classifies lines as lead, galvanized requiring replacement, or unknown, and you can look up your address on its interactive map at pipes.phoenix.gov. On private piping, older homes in central neighborhoods can still have galvanized steel, which rusts from the inside, while newer homes usually have copper or plastic.

Repair or replace

Before digging starts

Arizona 811 says that by law you must contact it before digging or trenching, and the service is free. Locators have two full working days to respond, so plan around that. Private lines such as irrigation, landscape lighting or a gas run to a grill may not be marked, so point out anything you know is buried.

What sets the price

Length of the run, depth, pipe material, what sits on top of the line, whether a permit is required from Planning and Development, and restoring landscaping or concrete afterward. A line that runs under a pool deck, block wall or mature tree usually costs more than one crossing open gravel. If the old pipe is galvanized or has already leaked in more than one spot, replacing the full run is often better value than a string of patches.
