Sewper Cover

The key to long-term sustainability for most municipal sewer systems rests solely on battling the force of nature, namely corrosion. For sewer systems, the common iron-cast manhole cover is often the first to feel the sting of trapped gasses like Hydrogen Sulfide that can degrade and rust metal leaving a mess behind.
Our new non-metallic, composite covers and rings removes the problem of corrosion right out of the equation. They wear longer, look better and can even be customized with logos and colors. It is the perfect solution for municipalities everywhere.
