Applications & Benefits



ADS Nyloplast stormwater inlets provide stormwater capture with a variety of ductile iron grate options integrally connected to a durable long-lasting PVC body. Traditional storm structure materials require maintenance and eventual replacement due to degradation from road salts, leaking joints, differential settlement, along with a host of other potential issues. 

Servicing heavy industrial and commercial sites to golf courses and residential yards, ADS offers specifiers and engineers the flexibility to design and build custom catch basin structures for their unique project needs. All of our structures including HP Manholes add longevity to your infrastructure.


Our HP Sanitary Manhole Structure is developed with SaniTite® HP Triple Wall Polypropylene Pipe.  These structures provide resistance to the corrosive effects of Hydrogen Sulfide (H2S) gas, superior durability, ease of installation, and lower installed costs.



Our line of structures is the clear choice for any water management application, with increased cost-efficiency, easier installation, custom designs and dependable strength.


Additionally, our line of drain basins, curb inlets and inline drains are all easily installed with minimum equipment and manpower. Capable of handling H-20 loads, Nyloplast structures provide a watertight seal with excellent economics. 

Nyloplast structures are available in customizable configurations and sizes with a variety of connection point solutions and pipe transitions.


Constructed from engineered plastics, our sanitary structures provide superior corrosion and abrasion resistance compared to traditional concrete, fiberglass or composite structures. They are engineered to install with just two joints and allow multiple opportunities for grade adjustment.

With short lead times and built-in safety factors, our lightweight structures are designed with cost efficiency and ease of install in mind.
