Downspout Infiltration

ADS downspout infiltration products provide a multitude of benefits to residential and commercial operations. Rainwater collection starts at the roof, with runoff being funneled from roof to ground from a N-12® Pipe. Through use of a pipe service connection like INSERTA TEE®, water is securely funneled from pipe to a subsurface stormwater management system. Our StormTech® products are the ideal retention detention system alternative. In addition to flood prevention, downspout infiltration products act as a rainwater storage for large volumes of water and lessens the impact on city storm sewer systems. Collected water can be used at a later date or irrigation. Useful and easy to install ADS leads in downspout infiltration solutions.


The optimal underground retention system for storm water runoff. StormTech® products allow for storm water to be securely stored for future irrigation or disposal, efficiently providing flood prevention and preventing runoff from entering into city storm sewer systems.

N-12 Pipe®

The ideal corrugated polyethylene drainage pipe. The pipe provides superior corrosion and abrasion resistance that makes it ideal for storm water drainage applications.


A connection system that joins your downspout pipe to the designated retention system. The INSERTA TEE is the ideal three part system that requires no special tooling to connect your pipe to your storm water retention and infiltration system.
