Cleaning and maintenance of pond inlets, outlets, pipes, grates and control structures so stormwater flows the way it was designed to.
Wimberley's stormwater systems do their real work during the flash events that move through the Cypress Creek watershed, and the inlets and outlets on local detention ponds take the brunt of it. When a grate clogs or a control structure jams, the pond stops functioning the way it was engineered to, and the next heavy rain has nowhere predictable to go. Inlet and outlet structure maintenance is how a property manager or board keeps that system doing its job instead of finding out it failed during a storm.
The limestone and cedar terrain around Woodcreek and the hillsides feeding Blue Hole mean shallow topsoil and fast runoff, so ponds here tend to load up with cedar needles, leaf litter and washed gravel faster than flatland basins do. We regularly find slow drawdown after rain because an outlet pipe is partly choked, a forebay silted in from hillside erosion, bare slopes where grass never established on thin soil, or volunteer cedar and hackberry seedlings taking root on an embankment and working their roots into the structure. Older developments handed off years ago often have a control structure nobody has opened since the engineer signed off on it.
Working with Corral Bros on this scope starts with a walk of the pond, inlets and outlets so you know exactly what is blocked, worn or growing where it should not be. We clear inlets and outlets, clean pipes and grates, remove debris and obstructions, and run flow and function checks so water moves the way the design intended. Any structural or engineering question gets handled alongside your property engineer or the plan on file, we just keep the system clear and working between those reviews.
We're a local, family-built company that treats your Wimberley property like our own, tidy crews, clear pricing, and inlet & outlet structure maintenance that holds up to Hays County conditions. Available as a one-time project or part of an ongoing plan.
We walk the pond, inlets, outlets and any control structures with you or your maintenance contact so we can see exactly what is blocked, silted, or overgrown before quoting anything. Estimates are free and no-obligation, and we usually get on site within 48 hours of your call. You get a clear scope based on what we actually find, not a guess from the road.
It depends on tree cover and slope, but many Wimberley properties near cedar-heavy hillsides or creek corridors need a clearing visit after the heavy spring and fall rain periods at minimum. Ponds that show slow drawdown, standing water around the outlet, or visible silt buildup after a storm are telling you it is due now, regardless of the calendar.
We schedule the work and stage equipment away from active parking areas and walking paths, and we coordinate timing with your office so residents or tenants are not surprised by crew trucks at the pond. Most inlet and outlet work is contained to the basin itself, so it does not interfere with day-to-day use of the property.
Shallow topsoil over limestone sheds water fast, so ponds here silt in faster and grow volunteer cedar and hackberry on embankments quicker than you would see on deeper, flatter soil. That combination means inlets and outlets clog with sediment and roots sooner than a property manager might expect, which is why a system that looked fine last year can need real attention now.
The biggest factors are how long it has been since the structure was last cleared, how much sediment and vegetation has built up, how many inlets and outlets the pond has, and how accessible the structure is for equipment. A pond with a choked pipe and an embankment full of seedlings takes longer than one that just needs routine grate clearing, so the site walk is what sets the actual price.
