Stormwater Cistern

A stormwater cistern is a large above ground container that captures rain from a roof downspout, then slowly releases it through a low flow valve to your yard or side sewer. This special low flow valve lets water trickle out to make room for rain from the next storm. In the late spring, this valve can be closed if the owner wants to use the rain for summer watering. Seattleites may get rebates for cisterns.
