FAQs about WEc1 :

Can non-potable well water that is used for irrigation contribute to potable water reduction?

Can surface water, such as water from an irrigation ditch or a local creek, be used as nonpotable water?

Do interior planters count in the calculation?

We are using non-potable water for irrigation. For drought conditions, can we hook up to a potable water source for backup and still earn this credit?

Retention pond off site

Hello, We are considering creating a retention pond area that would be adjacent to the LEED project but not in the LEED project boundary. The owner has some open space they may partially develop later that will contain the retention pond. Can water from there still be used to meet the requirements for this credit? John

There are two questions here, one about using a feature not within your LEED boundary, and the other about using surface water for irrigation. A nonpotable water source outside your project boundary (a good example is a municipal "purple pipe" system) can be used. However, surface water is not considered a nonpotable water source for the credit. See the credit language and the FAQ above.
