Innovative wastewater technologies

WEc2 | Possible 2 points


To reduce wastewater generation and potable water demand while increasing the local aquifer recharge.


Option 1

Reduce potable water use for building sewage conveyance by 50% through the use of water-conserving fixtures (e.g., water closets, urinals) or nonpotable water (e.g., captured rainwater, recycled graywater, on-site or municipally treated wastewater).


Option 2

Treat 50% of wastewater on-site to tertiary standards. Treated water must be infiltrated or used on-site.
