Underground detention and stormwater control measures (SCMs) for tight sites, parking lots and developments.
Subsurface stormwater control measures work hard in Manor because the east side of Travis County has gone from pasture to rooftops in a short stretch of years. ShadowGlen, Whisper Valley and Stonewater all sit on deep blackland clay, and that clay does not drink water the way sandy soil does. When a site engineer sizes an underground chamber or vault system for one of these developments, the system is doing most of the work the ground refuses to. If it is not inspected and cleaned, it backs up fast.
Blackland clay swells when it is wet and cracks when it is dry, and either way it sheds water into the nearest inlet instead of absorbing it. On new construction sites, that means a forebay loaded with sediment within a season or two, a slow drawdown after a hard rain, or an outlet pipe partly choked with silt and construction grit that washed in before the lot next door got sod down. We also see volunteer trees taking root on embankments around open ponds feeding these systems, roots that work into joints over time. On a flat prairie with heavy clay, water does not find a new path on its own. It sits, or it finds the weak point in the system.
For a property manager or board handling a finished site, or a GC closing one out, our part is straightforward. We walk the system, tell you what is silted, blocked or compromised, and get it cleaned, jetted or repaired to the plan your engineer already approved. No guesswork, no upsell, just the system doing what it was designed to do.
We're a local, family-built company that treats your Manor property like our own, tidy crews, clear pricing, and subsurface stormwater control measures that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
A subsurface stormwater control measure is used when there isn't room for a surface pond, tight commercial lots, parking areas and dense developments. The system goes underground (chambers, vaults or pipe galleries) and stores or infiltrates stormwater beneath the site, freeing up the surface for parking or building.
Yes. Subsurface SCMs accumulate sediment and debris and must be inspected, cleaned and jetted on a schedule to keep working and stay compliant. We service, clean and retrofit underground detention and infiltration systems throughout Central Texas.
We schedule a free on-site look, usually within 48 hours of your call, and walk the accessible structures, inlets and any vault or chamber access points with you. We note drawdown issues, sediment buildup and anything that looks off versus the as-built plan, then give you a straightforward estimate for inspection, cleaning or repair work before anything starts.
It depends on how built-out the surrounding lots are, since active construction sends far more sediment into a system than a finished, landscaped site does. New subdivisions on the east side often need their first cleaning sooner than an older property would, simply because grading and bare dirt upstream wash silt straight into the forebay and pipes.
Most subsurface work happens at access points, manholes, vaults and outlet structures, so we coordinate timing with your office to avoid peak traffic or resident hours. If a section of parking or a drive aisle needs to be closed briefly for access, we work out the window with you ahead of time rather than showing up and figuring it out on site.
Blackland clay does not infiltrate water well, so these subsurface systems carry a heavier load here than they would on sandier ground, and heavy rain events push sediment and debris into forebays and pipes fast. That shows up as slower drawdown after storms, silted intake structures, and occasionally roots from embankment trees working into joints near open pond connections.
Access and sediment load are the two biggest factors, since a vault that needs jetting through a tight manhole costs more time than an open forebay cleanout. Pipe length, how compacted or hardened the silt has become, whether roots or debris have damaged a structure, and how recently the system was last serviced all factor into the final number.
