Easy retrofit solution for stormwater systems and trash control

One of our municipal clients here in CT contacted us one day because he was often called by a local resident with complaints about trash, bottles, cans and other debris which had been thrown out car windows and would travel through the storm water system and end up in this resident's wetlands/backyard. The area is more of a suburban almost rural area, so you can imagine that all of this trash was even more visible and a real eyesore to anyone driving by. The resident was just plain tired of cleaning up after everyone else and the town needed a long term solution, extremely low maintenance solution to correct the problem. What could we suggest?

After a quick survey of the area, we saw the offending storm structure and realized the best alternative in this case would be our self-cleaning, stainless steel, wedgewire screen and orifice place.

If you are not familiar with wedgewire screens, they are very cool and have a wide range of applications - not only as trash and debris screens at hydro plants around the world, but also as fish exclusion in ponds/streams and another common use is in detention ponds to prevent trash/debris and small animals from getting into the system.

In this case, sediment, trash and debris would be prevented from entering the system, yet water could still flow through the system at high flow rates. It was an easy fix for this problem and the complaints stopped!

The top picture shows the screen after the first major rain storm. You can see the leaves stuck to the screen. When the system dries out, the leaves will fall off. The system is constantly working.

The picture of the red grate is the top of the structure and if the water gets high enough, it will flow into the system this way.

Our screens are highly engineered and designed for site specific applications.
