Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Detention pond sediment removal in Liberty Hill comes up a lot faster than most property managers expect, and the reason is simple: this city is still being graded. Santa Rita Ranch, Rancho Sienna, and the growth along Stonewall are pushing new phases of cleared ground into drainage systems built to handle a finished, landscaped watershed, not raw dirt. Basins designed for a stabilized site end up catching years of sediment in a single construction season.
Thin ranch soil over limestone does not hold water or dirt the way deeper soils do, so a hard rain strips topsoil fast and carries it straight downhill into the nearest pond. We see it as a silted-in forebay long before the main pool shows a problem, a slow drawdown that used to take a day and now takes three, bare or eroding slopes where grass never got established, and volunteer trees taking root on an embankment because nobody has been down there to pull them. The outlet structure is usually the first thing to choke and the last thing anyone checks.
Working with us on this scope means we come out, walk the basin, check sediment depth at the places that actually matter, and give you a scope that restores the pond's designed storage and grade rather than a surface cleanout. We handle the excavation, the forebay and outlet cleanout, and haul everything offsite for disposal, working on the schedule that fits an occupied property, an HOA board, or a GC trying to close out a job.
We're a local, family-built company that treats your Liberty Hill property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Williamson County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site visit, usually within 48 hours of your call, and walk the basin with whoever manages the property, whether that's a board member, an association manager, or a GC closing out a site. We check sediment depth at the forebay and main pool, look at the outlet structure, and note the condition of the side slopes. You get a straightforward scope and number before anything gets scheduled.
It depends on how much raw ground is still draining into the basin. A pond collecting runoff from recently graded lots or unfinished phases in a master-planned section can silt in within a couple of years, while an older, fully landscaped drainage area may go longer between cleanouts. Slow drawdown after a storm, water sitting past a day or two, or a visibly shrinking forebay are the signs it's due.
Yes, this is routine for us on occupied sites. We coordinate access and timing with property management ahead of excavation and hauling, keep equipment staged away from parking and walking routes where possible, and work the pond in sections if the site needs part of the basin or access road kept open.
Thin ranch soil over limestone means there is often very little topsoil holding back erosion, so cleared and graded lots upstream wash sediment into the pond fast after a hard rain. That sediment tends to settle heaviest in the forebay and near the outlet, which is exactly where we check depth first and where blockages usually start.
The main factors are how much sediment has to come out, how far it has to be hauled and legally disposed of, how accessible the pond is for equipment, and whether the outlet structure or forebay needs extra attention beyond a standard cleanout. Sites with mature volunteer trees on the embankment or limited equipment access typically take more time.
