well septic

A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater and in some cases greywater. It is a gravity-fed, vertical underground system that captures surface water from impervious surfaces, then stores and gradually infiltrates the water into the groundwater aquifer. Such structures are often called a soakaway in the United Kingdom or a soakwell or soak pit in Australia.
