Detention pond construction and maintenance, subsurface stormwater controls and pond water-quality management across Central Texas.
San Antonio has commercial detention basins that date back decades, and plenty of them have never had the bottom cleaned out. The ground on the north side is caliche over limestone, and part of Bexar County sits on the Edwards Aquifer recharge zone, so water quality structures get a close look. Older retail centers and office parks along the loops were built with steep side slopes nobody planned on maintaining.
Work starts with walking the basin and measuring how much sediment is sitting in the bottom against what the design allows. We haul that material off, mow the slopes on a cycle that keeps brush from taking hold, and clear inlets, outlet structures and trash racks so the pond releases at the rate it was sized for. Gullies cut into side slopes get regraded and stabilized. Storm lines and catch basins get vacuumed and jetted.
Most San Antonio accounts run on a scheduled contract, with mowing and inspections across the year and sediment removal when the measurements call for it. We can work from your engineer's drainage plan or from your management company's inspection reports, and every visit comes back with photos and notes you can put in a file. Call (737) 404-9343 and we will come look at your basin at no charge.

Yes. Corral Bros is a pond and stormwater contractor serving Central Texas, we build detention and retention ponds, maintain them, install and service subsurface stormwater control measures (SCMs), and manage pond water quality. Most of this work is for commercial properties, HOAs, developments and municipalities along the Austin–San Antonio corridor.
Detention pond maintenance keeps a basin working and inspection-ready: sediment and silt removal, mowing and vegetation control, clearing inlets, outlets and outfall structures, repairing erosion, and regrading as needed. We can also provide inspection documentation to support regulatory compliance.
In almost every case the property owner is, even when the pond serves several pads or sits in a shared drainage easement. The approved site plan and the plat notes usually spell out who maintains what, so that is the first paperwork to pull. If the center has separately owned pads, the cost often gets shared through the CAM structure, and we can bill it that way.
Letters normally list specific items like excessive sediment, blocked outlets, overgrown slopes or erosion. We inspect, match our findings to what the letter says, and do the work in the order that closes the items out. You get dated photos of before and after so there is something to send back with your response.
It depends on how much bare or disturbed ground drains to it, not on a calendar. A basin collecting runoff from a stable, fully landscaped site can go many years, while one downhill from an active construction phase can lose capacity in a season or two. We measure depth against the design on scheduled visits and tell you when it is getting close.
Yes. We open the access lids, vacuum out the settled material, jet the pipe runs and check the weirs, orifice plates and any filter media. These systems are confined spaces, so the crew and equipment are set up for that, and we document what came out and how much.
We do. Water quality structures on those sites are built to hold back sediment, which means they fill in and need cleaning more attentively than a plain detention pond. We keep the material contained on site during the work and haul it off rather than stockpiling it where the next rain moves it.
