Cleaning and maintenance of pond inlets, outlets, pipes, grates and control structures so stormwater flows the way it was designed to.
Inlet and outlet structure maintenance in Pflugerville is steady, necessary work, not a one-time fix. Between Falcon Pointe, Blackhawk, and Avalon, most of the detention ponds serving these subdivisions and commercial parks were built on heavy black clay, and that ground drives how fast an outlet structure clogs and how long a basin takes to drain.
Black clay cracks wide open in a Texas drought, then seals shut and sheds water hard once the rain finally comes. That cycle moves a lot of fine sediment into forebays and inlet grates in a short burst, which is why we see slow drawdown after storms, silted-in forebays, and outlet pipes running half their capacity. Add in bare or eroded slopes, volunteer trees rooting into an embankment or control structure, and grates packed with leaves and trash from a busy parking lot, and a pond that looked fine in July can be holding water it should not be holding by October.
Working with Corral Bros on this scope starts with a straightforward site walk, not a sales pitch. We open the structures, tell you what we find, and clear inlets, pipes, grates, and control structures so the system moves water the way it was designed to. For property managers, HOA boards, and GCs closing out a site, that means one call, a crew that knows what a Central Texas basin looks like after a dry spell and a hard rain, and work done to your plan or alongside your property engineer when one is on record.
We're a local, family-built company that treats your Pflugerville property like our own, tidy crews, clear pricing, and inlet & outlet structure maintenance that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
We walk the pond with you or your maintenance contact, open the outlet structure, and look at the inlets feeding it. You get a free no-obligation on-site estimate, usually scheduled within 48 hours, with a plain description of what is blocked, silted, or growing where it should not be.
Most Pflugerville basins need a check once or twice a year, with heavier work after a hard rain event or when a board notices water sitting longer than usual. Clay soil sites in Avalon and similar subdivisions often need more frequent outlet clearing because fine sediment settles out slowly and compacts near the structure.
Black clay shrinks and cracks hard in drought, then seals up fast and sheds water once it finally rains, which pushes a heavy sediment load straight at the inlet and forebay. We often find silted-in grates and slowed drawdown at commercial parks and HOA ponds built on this ground, which is exactly what inlet clearing and flow checks are meant to catch.
We coordinate timing with the property manager or association contact ahead of the visit so the crew is not blocking a leasing office entrance or a resident's assigned spot. Most inlet and outlet work happens at the pond itself, away from main traffic areas, so normal business and resident activity continues around us.
The biggest factors are how much sediment or debris has built up, how many inlets and outlets the system has, and whether volunteer trees or heavy brush have rooted into the embankment or structure. A basin that has gone a few years without attention costs more to clear than one on a regular schedule, so we price each site after the walk rather than guessing over the phone.
Yes, where a site has an engineer of record or a specific outlet control design, we do the clearing and upkeep work to that plan rather than making our own changes to the structure. We are a maintenance and site contractor, so any redesign or certification stays with your engineer, and we handle the cleaning, debris removal, and flow checks that keep the system working as designed.
