Morning, I’m starting with calculations in SS credit 6.1 and 6.2 and I have a question: We are implementing rainwater recapture on our project for irrigation and toilet flushes.

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 t

Is it acceptable to utilize an existing detention pond that is outside the proposed LEED boundary? The stormwater runoff will be piped under the existing road to the pond.

Does discharging the collected rainwater to municipality facilities will help with achieving the requirements for credit 6.1 & 6.2? we are following Case1 - path 1, we will reclaim the rainwat

Michael, Our local regulations usually require rainwater collection facilities that only shift the total runoff between storms instead of infiltrating or reusing the rainwater. Is there a common

Good Morning, I’m starting with calculations in SS credit 6.1. But I have a question: Can I use the runoff data of the watershed where is located the project?

Hi all, We are working on a project in Prague with imperviousness >50% (Case 2).

How is design storm interval determined? I looked into the LEED BD+C Reference Guide on page 97 in the example (last calculation) at the top of the page.

Will capturing all rainwater and keep it in a tank for future uses such as cooling towers and irrigation? Our project will not infiltrate it but reuse it instead.
