Stormwater Detention



R-Tank & Flo-Well Systems

Custom R-Tank installations and designs provide underground storage of stormwater.  This system can be used for detention, infiltration and recycling stormwater when the site/property is flat with limited slope for pipe outlets above grade.  R-Tank and Flo-Wells are both now commonly used as underground detention media as required by developing STL municipal ordinaces for collecting stormwater from non-pervious surfaces such as roofs and pavement.  R-Tanks are more efficient and allow easier access for future maintenance.  Flo-Wells are more ideal for smaller applications.  We offer design, installation, and annual maintenance inspections for all underground storage systems and stormwater cells.  

Cistern Systems

Custom cistern installations and designs are available in poly and precast materials with capacities varying between 750 to 1,800 gallons.  Packages can be offered using both automatic irrigation systems and hand operated lift stations. Conventionally, guttering downspouts and area drains for your property are integrated into the cistern system.

Water Repurposing

Rain Water Storage

Rainwater Harvesting

Rainwater and stormwater collection is a smart and environmentally friendly practice that can also save you money on your water and utility bills. It also lessens the amount of water racing into the storm sewer at peak times.

The average American uses about 100 gallons of water per day for showers, toilet flushing, clothes washing, cooking and lawn watering.

ASL & Drainscapes designs and provides systems capable of harvesting rain water, without causing further problems related to guttering and drainage.
