CS-2009 SSc6.1: Stormwater Design—Quantity Control
Our project is capturing rainwater and sending it to a water table tank (I don't know if this is the correct term, it is the tank that recieves water from the water table below foundations).
The tank is big enough to comply with credit compliance, but I am wondering if LEED requires a specific tank dedicated to captured rainwater or if we can use this water table tank to fulfill credit requirements.
Thanks

David,
As long as the tank is sized big enough for both functions it should be fine. We've seen storage tanks that have multiple functions being allowed - for example, a tank that originally was only to be used for storing fire protection water was increased in size and used also to store rain water.
In our area, we've used the term "de-watering" for ground water that is pumped out from below a foundation, but it sounds like the same thing.
