Removal of water, sediment, sludge, trash and debris from underground detention vaults and the stormwater components tied to them.
If your property has an underground detention vault, the county and your site plan hold you responsible for keeping it functional, not just present. In Marble Falls, that means somebody on your board or management team has to know what is sitting under that parking lot or common area, and when it was last opened up and checked. Corral Bros handles underground detention vault cleaning for properties across Marble Falls, from Gregg Ranch to Meadowlakes to Horseshoe Bay.
The ground here does not do your vault any favors. Pink granite outcrops and thin, rocky lake soil mean rain runs off fast and carries grit and debris straight into the system instead of soaking in upstream. We find forebays silted in hard, outlets partially choked with gravel and leaf litter, and drawdown that takes days longer than it should after a storm. On older sites around the lake, volunteer trees and brush taking root on the embankment are often the first visible sign that water is sitting where it should not.
Working with us on this looks straightforward. We get access to the vault, open it, and tell you what we found before we talk about a plan. If your site has an engineer of record, we work alongside their plan rather than around it. You get sediment, sludge, trash, and standing water removed from the vault and its connected pipes and chambers, done with confined-space safe practices, so the system drains the way it was built to.
We're a local, family-built company that treats your Marble Falls property like our own, tidy crews, clear pricing, and underground detention vault cleaning that holds up to Burnet County conditions. Available as a one-time project or part of an ongoing plan.
You or your engineer gives us access to the vault lid or hatch and we send someone out, usually within 48 hours, to open it and take a look before quoting anything. We measure sediment depth, check the outlet and connected pipe runs, and note confined-space entry needs. The estimate reflects what is actually inside the vault, not a guess based on the size of the property above it. There is no obligation and no charge for the walk.
Most vaults in Gregg Ranch, Meadowlakes, and Horseshoe Bay need attention every two to four years, but a storm event or a sediment-heavy watershed can move that up fast. Your engineer or the original site plan may specify a maintenance interval, and we will follow that. Slow drawdown after a rain, standing water that will not clear, or a rising sediment line on the vault wall are all signs it is due sooner than the schedule says.
We coordinate access and timing with the property manager or HOA contact ahead of the work, since most vault hatches sit under drive aisles, parking rows, or common ground. Dewatering and sediment removal equipment needs a staging spot near the hatch, so we work out which spaces or lanes need to be clear and for how long. Residents and tenants generally see a crew and a truck, not a disrupted parking lot for days.
Pink granite outcrops and thin, rocky soil around Marble Falls shed rain fast instead of absorbing it, so vaults here tend to load up with coarse sediment and grit rather than fine silt. That grit settles hard in the forebay and can work into connected pipe runs and chamber joints. It also means an outlet partially blocked by gravel and debris is a more common finding here than it would be on deeper soil.
Sediment depth and volume drive most of the cost, along with how much standing water needs to be pumped out before we can get in. Confined-space entry requirements, the condition of connected pipes and chambers, and how much trash and debris has collected also factor in. A vault that has gone a long time between cleanings, or one tied to a larger drainage run with multiple chambers, will run higher than a vault on a regular maintenance cycle.
