So plumbing arrangements shall be made as a separate line which can direcly deliver for reuse application. Also we need to have our LEED forms that captures these applications to the v5 forms. This will balance the water need even during summer season. Also completely remove the power associated with recycling process. And also motivates the people to encourge this application in their facities/homes.
