The EnviroHood Sell Sheet contains information about the Nyloplast® EnviroHood™, a stormwater management device designed to prevent the outflow of floating debris and oil from a catch basin or manhole.

The Nyloplast EnviroHood prevents debris and oil from entering our lakes, rivers and streams. The need for cleaner stormwater has caused municipal leaders to demand forward-thinking solutions to improve the overall water quality of stormwater. Dirty and contaminated stormwater contributes greatly to water pollution. The Nyloplast EnviroHood offers a cost-effective way to improve overall stormwater quality, providing lower installed costs and less intrusive installations than competitive devices in the market.

The Nyloplast EnviroHood is engineered for optimal performance & uses the same proven corrugation technology used on ADS N-12 pipe products. This delivers maximum strength to weight ratio and ensures the structure is capable of supporting the hydraulic forces of a rainfall event.

The Nyloplast EnviroHood is molded from High Density Polyethylene (HDPE) with a lightweight and sturdy design. The corrugated design eliminates flat surfaces and provides increased structural capacity.

It is an effective low-cost solution for stormwater treatment & easy to clean. The Nyloplast EnviroHood is highly corrosion-resistant for long service life.
