The Polylok Drain Well is an easy to install dry well used to collect, retain, and discharge storm water. Our Drain Well allows the flexibility to choose your inlet and leaching locations. The Drain Well cover allows for a 4" surface drain and is equipped with two recessed handles for easy removal. One of our Drain Well's greatest features is its ability to accommodate stacking of Polylok 24" risers to accommodate higher volumes of water.
