GW TREATMENT
GW Treatment is the removal of any unwanted material from the greywater col-
lected, making it useful and safe for toilet flushing, irrigation, etc..
GW Treatment plants are located on site and sized for the output capacity. (NSF /ANSI Standard, 2011.)
NFS 350 C Certified Treatment is approved by the U.S. Green Building Council for overhead spray irrigation,
water features, toilet flushing, and replenishing cooling towers.
BENEFITS OF A GREY WATER SYSTEM
GW recycling can decrease potable water use by 30 - 40%, depending on the site. can reduce up to 100% of landscape potable water use.
