| Basin Maintenance & Water Quality Pond Services |
 | |  | |  | |  | |  | |  |
We provide water quality pond maintenance services including: Inspections,
Sediment Removal, Mowing, Debris & Litter Removal, Erosion Control and
Nuisance Control.
In the Austin area most parking lot owners are required to protect the creeks,
rivers and lakes from pollution which is washed off from parking lots, and
other impervious surfaces when it rains. We can assist you with regular
maintenance, repairs and sediment removal to keep your water quality pond
working well and looking good.
Silt accumulation on the surface of the filter media should be removed when it
has reached a depth of about 0.5 inch or the drainage time has increased to
more than 48 hours, is advised by the Texas Commission on Environmental
Quality for property over the Edwards Aquifer Recharge Zone.
Some of the local authorities which have water quality maintenance
requirements are listed below. Click one of the four below underlined links to
view and learn more about their current water quality regulations.
1) The City of Austin
2) The City of Bee Cave
3) The Lower Colorado River Authority
4) Texas Commission for Environmental Quality (TCEQ)
We provide full service bi-annual regular inspections, testing, excavation, haul
off and disposal of the sediment which naturally collects, to clean up and
maintain the functionality of your parking lot water quality sedimentation /
filtration pond or basin.
Water Quality Ponds/Basins are some times called (BMPs) Best Management
Practices, they can be called sand filter basins, sedimentation/filtration ponds,
SOS ponds, wet ponds, extended detention ponds and various other names.
These water quality basins filter the rainfall runoff from parking lots, and
should be inspected a minimum of 2 times a year for maintenance and
occasional sediment removal. Commercial Engineering utilizes our vacuum
excavation equipment to remove sediment and the crust which naturally
builds up in the sediment collection areas.
By using our mobile vacuum sediment excavation machinery we are able to
safely overcome many maintenance accessibility limitations, such as walls,
fences and rock gabion baskets.
Below is a cross-sectional view of a typical sand filter system. A filter fabric
separates the sand layer from the gravel support bed around perforated
plastic PVC underdrain pipes. The science behind this filter system has been
used for hundreds of years to purify water and remove pollutants.
For Edwards Aquifer water quality basins a sediment sample is first collected,
then lab analyzed and reviewed by the TCEQ before any sediment removal
and disposal. Several federal and state laws and regulations may apply to the
disposal of sediments which accumulate in stormwater systems or which are
captured by street sweepers, according to the Complying with the Edwards
Aquifer Rules: Technical Guidance on Best Management Practices.
If you are into the science of it, TCEQ reviews lab analysis of collection
samples to monitor the concentration of 3 different heavy metals and the
petroleum hydrocarbons content (vehicle fluids) so that it can be disposed
properly, in the correct type of landfill.
Some other general maintenance checklist items we can help you
with include:
Inspections
Sediment Removal
Media Replacement
Debris and Litter Removal
Filter Underdrain Cleaning
Mowing and vegetation maintenance
Erosion Control
Nuisance Control
Repair of corrosion
Pump service and dewatering
Masonry rock wall and concrete mortar repair
Repair rock gabion basket structures
By keeping the ponds functioning properly and
you can do your part to protect our beautiful
environment here in Austin.
