Detention pond construction and maintenance, subsurface stormwater controls and pond water-quality management across Central Texas.
San Marcos packs a lot of apartment property and retail into a small footprint, and on tight sites the detention is often underground, in vaults or oversized pipe under the parking lot. Out of sight means out of mind until it stops draining. The San Marcos River is spring fed and the city pays close attention to what reaches it, so water quality structures on commercial property get looked at seriously here.
Underground systems get vacuumed out, the pipe runs jetted, and the inlets and weirs cleared so the system holds and releases the way it was built to. Above ground we mow slopes, pull trash and silt from the bottom, clean the forebay and repair eroded inlets. Student-heavy properties generate a lot of litter, so trash removal is a real part of the job here rather than an afterthought.
For apartment and student housing managers in San Marcos, we schedule around turnover season so the work does not land in your worst week of the year. Vault cleaning is confined space work and we come equipped for it, with documentation of what was removed. Ask us to open a lid and look before you build next year's budget.

We also provide ponds & stormwater in these nearby communities:
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.
It depends on how dirty the drainage area is, but most parking lot systems need attention every year or two, and some sooner. The honest answer comes from opening the lids and looking at how much has accumulated. Once we have seen yours a couple of times we can set a frequency that matches the actual rate.
Yes, and on multifamily sites that is often where the problem starts. Litter, leaves and silt collect in the inlets, then the whole system backs up at the first heavy rain. We vacuum the basins, jet the lines and clear the grates as part of the same schedule as the pond.
Sedimentation and filtration systems are built to capture material, so they eventually clog, and a sand filter or filter media bed that has sealed over will hold water for days. Cleaning the media surface, clearing the underdrain and removing accumulated sediment usually restores the drawdown. If it comes back quickly, something upstream is feeding it more than it was designed for.
That is usually the best time and we plan for it. Summer gives us open parking for equipment and fewer residents to work around. Scheduling the heavier items then and keeping routine mowing year round works well on student housing.
You keep the records and provide them when asked. We give you a dated report with photos and a description of what was done, which is what owners and management companies typically hand to a reviewer. We are a maintenance contractor, so anything requiring a professional engineer's certification goes to your engineer.
