17 results about "Dry well" patented technology

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 covered, porous-walled chamber that allows water to slowly soak into the ground (that is, percolate), dissipating into the groundwater. Such structures are often called a soakaway in the United Kingdom, a soakwell in Australia, and a soak pit in India.
