There are a number of UltraTech stormwater management products for standard storm drains. A smaller number of combination drains: but still a fair amount. So when we were challenged by a customer for a solution to keep residual fuel from being washed down their trench drains, we were surprised that there wasn't something already available. The challenge with most trench drains is their shape: long, narrow and shallow. That combination makes typical drain solutions impractical. With the Ultra-Trench Filter Boom, we move the filtering solution above the drain and actually treat the water before it even reaches the drain. Using X-Tex material, hydrocarbons are quickly removed and captured from the stormwater flow, allowing only clean rainwater to flow into the trench drain.
