STORMWATER BASIN MANAGEMENT
WHAT WE DO
Our mission is to provide outstanding maintenance and service for stormwater retention and detention basins in the Edwards Aquifer region of Texas. We specialize in environmental regulatory compliance for a broad range of basin types.
Filtration Basin Maintenance
Stormwater filtration basins (Water Quality Ponds) are maintained in accordance with local regulations, Austin Watershed Protection Department or San Antonio Water System and state regulations, Texas Commission on Environmental Quality. All water quality ponds must be maintained to their original specification.
Regular service includes removal of sediment, debris, vegetation, and trash. All vegetation must be trimmed and vegetation in the filtration chamber (sand) must be removed. Compliance work is done to remove any notice of violation (NOV) from the city and maintenance is performed to keep basins compliant.
Subterranean Basin Maintenance
Underground water quality ponds (subterranean basins) function the same as outdoor filtration basins, but the often require special access and additional safety precautions. In San Antonio, subterranean basins manufactured by Contech are common.
Engineer Drawdown Reports
Subterranean Basins must be inspected annually by an engineer and receive a “Drawdown” report that shows the basin drains in the correct amount of time. After a rain event, an engineer observes the basin and the water level. Then, after ~72 hours, checks the basin again to make sure the water has drawn down the appropriate amount.
Austin requires that this report be prepared and sealed by a professional engineer.
Stormwater Wet Pond Inspections and Maintenance
Stormwater filtration basins (Water Quality Ponds) are maintained in accordance with local regulations, Austin Watershed Protection Department or San Antonio Water System and state regulations, Texas Commission on Environmental Quality. All water quality ponds must be maintained to their original specification.
Regular service includes removal of sediment, debris, vegetation, and trash. All vegetation must be trimmed and vegetation in the filtration chamber (sand) must be removed. Compliance work is done to remove any notice of violation (NOV) from the city and maintenance is performed to keep basins compliant.
Aquatic Vegetation Removal
Neglected stormwater ponds can accumulate excessive aquatic vegetation. We dredge the bottom of ponds to remove invasive plants by the root. This is far more effective than the more common treatment of cutting the plants.
We use a specialized pontoon excavator that is designed to operate in ponds. Lily pads are common invasive plants as well as algae, Cattails, and other weeds.

WHY YOU SHOULD CARE
It's the Law
The Texas Commission on Environmental Quality (TCEQ) requires that stormwater basins be functioning properly and maintained regularly. Properties found to be out of compliance with the TCEQ regulations will be fined if corrective action is not taken. The TCEQ can even put a lien on a property that is found to be non-compliant.
It's Important for Our Water
Stormwater basins in this region of Texas don’t just prevent flooding and contain stormwater during heavy rains, they filter the water before it returns into the Edwards Aquifer. These special basins are known as filtration basins. These basins in central Texas require special attention because of the Edwards Aquifer recharge zone is environmentally sensitive, and stormwater can contain many contaminants.
BASINS 101
There are many types of stormwater basins designed for the Edwards Aquifer Recharge Zone, but the most common type is the Sand Filter System, commonly referred to as the filtration basin. Originally designed in Austin, Sand Filter Systems have become the standard method for small or medium sized properties to filter their stormwater.
Stormwater flows into the basin, is filtered by the sand, and the clean water flows out and eventually back into the aquifer.
As the sand filters dirty stormwater, a layer of contaminants builds up on top of the sand. This contaminant layer, if left unattended, can form an impermeable surface that prevents water from properly filtering through the filtration basin.
Keeping the sand free of contaminant buildup is critical to keeping the basin functioning properly and within the regulations set by TCEQ.
