WEpc10 through use of cistern

Hello, Latest one of my projects pursuing this pilot credit is a daycare facility. Adult toilets are low flow, but child sized toilets are standard 1.6gpf. There are no urinals included in the project. Over 100% of the calculated annual demand for these flush fixtures is being met by a poured in place cistern which collects rainwater from a multi-gabled steep sloped roof via gutters/roof drains and also condensate from the outside air ventilation system during the more humid months of the year. ( hot/humid Florida spring thru early autumn) This is also one of the primary stormwater run-off mitigation strategies for the small site on which this project is located. The project will be eligible for all WEc3 points, WEc2 points, and Exemplary Performance of WEc2 along with this pilot credit making Water Efficiency a strong success story for the sustainability features of the project!
