Our detention tanks have flat bottoms that allow easy pit excavation. The tanks have protrusions at the bottom which means that the fill holds the tank down if the ground becomes water saturated. An empty in saturated earth acts like a boat and tries to pop up out of the ground.
Our clever system allows for easy orifice size holes as specified. The overflow is integral part of the tank.
Our range of detention tanks is from 1000L to 5000L
