Underground Utilities in San Antonio, TX

Underground Utilities · San Antonio, TX

Water, sewer and storm lines trenched and backfilled

Pipe is the part of a job nobody sees until it fails. Water lines, sewer lines and storm drains go in before the slab, the drive or the parking lot. Global Contractors LLC works as an underground utility contractor across San Antonio and about 50 miles around the city. We trench, bed the pipe, backfill it and put the ground back at grade.

The company has dug and piped sites since 2006. A job here can be one service line into a house, or every line under a tract during site preparation. We work for builders, general contractors, developers and property owners. Call (253) 606-9497 and we will come look at the job.

  • Sanitary sewer lines, laterals and cleanouts set to line and grade

Water Main, Water Line and Sewer Line Installation

Most of this work is a trench, a pipe and a good backfill. We cut the trench to the depth and the line the plan calls for. The pipe sits on bedding material, not on rock or lumps of clay. Then the trench comes back up in lifts, compacted as it goes.

Sewer runs on grade, so the fall matters more than anything else. We shoot the line, set the pipe to it and check it before the trench closes. Water lines care less about slope and more about cover and thrust. Sewer line replacement runs the same way, with the old pipe pulled and the new one tied in.

Utility work is where this company came from. For decades the jobs were storm systems, water and sewer lines and excavation for cities, counties, schools and the military. Public jobs run off plan sets and inspections, and private jobs here get the same treatment.

Do you have to call Texas 811 before you dig?

Yes, and the law is specific about it. The Texas Utilities Code counts almost any powered digging as excavation once you disturb soil 16 inches down. Trenching, boring, grading and backfilling are all named in it.

The ticket goes in ahead of the work. The code allows it no earlier than 14 days out and no later than 48 hours before. Weekends and legal holidays do not count toward that window. We file it, the operators mark their lines, and we dig to the marks. Holding a permit or an easement does not take the place of that call.

Water and sewer lines are Class B facilities under that code. The notification center warns that they may not get your ticket at all. Electric, gas and telecom usually respond. We open those areas slowly and dig by hand where marks look thin.

Culvert Installation and Storm Drain Work Around San Antonio

Storm work moves water off the site and into something built to take it. That means inlets, pipe, headwalls and the grading that feeds them. On a commercial site it often ends at a detention pond.

Driveway culverts come with a permit question. A drive that ties to a state highway needs a TxDOT access driveway permit. The property owner or their representative applies for it. TxDOT also wants any drainage impact on the highway coordinated before local approval. On a county or city road the local office says what size pipe goes in.

Work in a San Antonio street adds its own paperwork. Public Works requires a permit before anyone excavates or uses the right of way. The city's Utility Excavation Criteria Manual sets the technical standard for that work. On SAWS permits that call for it, a SAWS inspector has to accept the sewer connection.

How We Work

How a Job With Global Contractors Runs

From the first call to the final grade, here is how it goes.

1

You call

Call (253) 606-9497 and tell us what the site needs: a lot cleared, a house down, a pad built. We ask enough questions to know what machines the job takes.

2

We look at the site

We drive out and read the ground: access, slope, trees, utilities, what is standing and where the dirt can go. On a build we go through the plans with you.

3

You get a written estimate

The scope and the price go in writing, broken out so you can see each part of the job. Estimates are free, and so is the site visit.

4

We do the work

Permits and utility locates come first where they apply, including the Texas 811 call before anyone digs. Then the excavators, the trucks and the mulcher go to work.

5

The finish

Spoils get hauled off or spread on site, and the ground is graded before we pull off. We go over the finished job with you while the equipment is still there.

FAQ

Underground Utilities Questions, Answered

Common questions about underground utilities across San Antonio and about 50 miles around the city. If yours is not here, call and ask.

Call (253) 606-9497

How much does it cost to put in a water or sewer line?
Length and depth set most of it. A short service line in sandy ground is a different job from a long run through limestone or caliche. Crossing a driveway, a street or a creek pulls in pavement repair, shoring and inspections. We look at the site and the plan first, and the estimate is free.
Do you install septic systems?
No. In Texas a septic system is installed and permitted by a TCEQ-licensed installer, and the county issues the permit. We handle the other underground work on a property: water lines, sewer lines, storm drains, culverts and trenching for other utilities.
Can you put in a driveway culvert?
Yes. We size the pipe against the ditch, set it, backfill over it and shape the ditch back. Permits depend on whose road the drive ties to, and we will point you at the right office. Culverts also go in on ranch roads and crossings where a low spot holds water.
Can you replace an old sewer line or water line?
Yes, by open cut. We locate the run, trench it, pull the old pipe and lay the new one. The tie-ins at each end are the fussy part. On a SAWS service connection the plumbing end runs through a licensed plumber.
What happens to the dirt out of the trench?
Good spoil goes back in as backfill, compacted in lifts so the trench holds. Rock, wet clay and extra material leave on the trucks, which is dump truck hauling. On bigger sites we spread usable spoil on the property instead of hauling it.
Can you do the site work and the utilities on the same job?
Yes. Most of what we do is excavation, so the pads and the trenches come off one contract. Utilities usually go in after rough grade and before the slab or the paving. Putting it all on one estimate keeps the machines from moving in twice.
