Underground dry well that accepts runoff from downspout extensions and French drains, then leaches it slowly into the surrounding soil. Each unit holds 50 gallons and connects to standard 4-inch pipe. Stacks and links to increase capacity — a 3-unit installation handles up to 150 gallons. Designed for sites where the water table allows percolation and where a pop-up emitter would discharge too close to the foundation.
