Can the following types of water, if stored in a rainwater cistern, contribute to credit compliance?
- Water from building foundations (dewatering) pumped into the rainwater cistern,
- AC condensate drained into the rainwater cistern.
If yes, can you also share your experiences on how you have approached the volume estimation for these sources?

Check the addendum (2/2/2011) "Additionally the credit can be met when landscape irrigation is provided by raw water (excluding ... ground water) that would otherwise be treated specifically for non-potable uses...." So it's a yes on the AC condensate, the water from your foundation is questionable. I believe I read somewhere that that's ok too. But I can't recall where.
