Turf Drain PERMA BASINS

Patented by TDA, Perma Basins not only collect surface water like other basins but have permeable sidewalls to collect seepage water and firm up the soil profile around the basin.

Different models are available depending upon the depth needed to collect seepage water. Standard units range from 18” to 6 feet deep, and can be custom made to any size.

All models have universal sleeves that allow the installer to connect 4” to 8” pipe without special fittings. Seepage drainage collection lines and solid outfall pipes can be graded through the same sleeve. They are made of cast aluminum, have a clean appearance, as well as the largest grate opening in the industry to help reduce the “trashing over” from grass clipping that is common with other types of basins.
 
Perma Basins are ideal for in-house drainage projects, including retrofitting older plastic basins that tend to “trash over” because of narrow openings. Additional drainage lines can be added at any
time.
 
Perma Basins are specified by architects for new construction projects because they are easy to install, firm up the soil around the basin, and are flexible for future needs.
