Similar to how in Location and transportation, you can achieve many points by doing a LEED ND site. You could have an Alternate Compliance path that allows you to earn many points by doing a combination of water collection and use and demand reduction for the totality of the water demand that you want us to calculate in the IP section. Seems easy to do, and would synergize all of these credits and promote water collection. Right now, you can earn 5 water points without collecting a single drop for less than 5,000 dollars. In order to earn the other 5 you might have to spend 500,000. This is a disparity that should be eliminated by synergizing all of these credits and emphasising what is a well known sustainable solution - Water collection and Reuse.
