Removal of water, sediment, sludge, trash and debris from underground detention vaults and the stormwater components tied to them.
Underground detention vaults in Lakeway have one job: hold back stormwater before it reaches Lake Travis, and give sediment a place to settle before the pipe does. The limestone hillsides through The Hills, Rough Hollow, and Flintrock shed water fast rather than absorbing it, which means every vault tied to those slopes is working harder than one sitting on flatter ground. Thin soil over rock does not filter much, so the sediment that would normally stay upslope ends up in your vault instead.
That shows up in predictable ways once we pull a lid. A forebay silted in tight enough that it no longer slows the first flush. A vault that drains slower than it used to after a heavy rain, because the outlet is partially packed with limestone fines and leaf debris. On older sites in Rough Hollow and The Hills, root growth from embankment trees that were never supposed to take hold can work into a joint or crack a weir wall. Flintrock's newer builds tend to show trash and construction grit from recent build-out instead, washed straight in before turf and landscaping fully established.
Call us and we walk the vault with you or your site engineer, confirm access and confined-space requirements, and give you a straight estimate, usually on-site within 48 hours. We dewater, pull sediment and sludge, clear trash and debris, and clean the connected pipes and chambers so the system draws down the way the design intended. We work the scope to the plan already on file for the property. No guesswork, no upsell, just the vault put back to doing its job.
We're a local, family-built company that treats your Lakeway property like our own, tidy crews, clear pricing, and underground detention vault cleaning that holds up to Travis 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 vault with whoever manages the property or the project engineer. We check access points, confined-space entry requirements, and the condition of the forebay and outlet before quoting. You get a straight number based on what we actually find, not a phone guess.
It depends on the watershed above it, but limestone hillside sites tend to need attention more often than flatter ones because runoff carries more sediment with less soil to filter it. Slow drawdown after storms, a visibly full forebay, or standing water that lingers longer than it used to are the usual triggers. Many boards schedule inspection and cleaning on a set rotation rather than waiting for a problem.
Yes, that is most of what we do. We coordinate access timing with property management, stage equipment to keep drive aisles and resident parking open, and schedule confined-space entry work for low-traffic hours when the property calls for it. Golf-course communities and retail centers each have different constraints, and we plan around them before the crew shows up.
Thin soil over limestone means less natural filtration, so sediment and fines move downhill fast during Hill Country storms and collect in the vault and forebay. That can mean more frequent sediment removal than a property built on deeper soils would need. Volunteer trees on embankments above older vaults are also something we check, since root intrusion is common on sites that have gone a while without clearing.
Depth of sediment and sludge, how much trash and debris has accumulated, how many connected pipes and chambers need cleaning, and how difficult access is all factor in. A vault with a single easy lid costs less to service than one needing multiple confined-space entries or extended dewatering. We confirm all of that during the site walk before we quote, so the number reflects the actual job.
