Front 15

What are the requirements of WE Credit 2: Innovative Wastewate Technologies?

Back 15

1) Reduce potable water use for building sewage conveyance by 50% through the use of water-conserving fixtures (water closets, urinals) or non potable water )captured rain-water, recycled graywater, and on-site or municipally treated wastewater. 2) Treat 50% of wastewater on-site to tertiary standards. Treated water must be infiltrated or used.
