Your Repair Options
Ownership is worth understanding before the first quote. The water utility owns the main under the street and, in most cases, the meter itself. The pipe running from that meter box to your house is the property owner's responsibility, and it is nearly always the part that fails. That is also why a leak in your yard rarely gets fixed by reporting it to the utility. The main shutoff for most homes around San Antonio sits in that same meter box at the curb, under a rectangular lid, and knowing where yours is turns a flooded yard into a manageable problem.
Why these lines fail here comes down to soil and age. Expansive clay across the eastern and northern suburbs swells after rain and shrinks hard through a dry summer, and a buried line gets pulled at every joint as the ground moves under it. Farther north the trench is cut into shallow limestone, where a pipe resting against rock wears at one point instead. Add older galvanized or polybutylene supply lines in houses built before the mid-1990s, and the pattern is consistent: the failure is in the pipe material, not in anything you did.
The two realistic routes are an open-cut repair and a replacement that pulls new pipe along the existing path with only an entry and exit pit. Trenchless work is not always possible, since driveways, mature tree roots, rock and the depth of the line all affect it, but it is the right question to ask when the line crosses a lawn you care about. Ask which one is being quoted, how the yard will be left, and whether the new line will be pressure tested and flushed before it is buried.
If the water is showing up inside instead, slab leak repair covers lines under the concrete, and burst pipe repair covers a split you can actually reach. Not sure which one you have? Start with leak detection, or browse every option on the plumbing services page.
Water line work covers San Antonio and the surrounding communities, including New Braunfels, where new subdivisions and century-old streets sit side by side. See the full service area list or tell us what you are seeing in the yard.
