Laundry waste water is Graywater, Laundry wastewater can be reused directly in sub grade outdoor irrigation uses. Unless! treated, then it is no longer Graywater, it is onsite treated waste water. Treated wastewater is treated to the degree needed for the use/reuse. In most places in USA there needs to be a treatment system that is NSF 350 compliant to reuse Graywater indoors. There are specific requirements in different regions. The IAPMO Green Plumbing Mechanical Code Supplement or GPMCS is a printed code supplement that any regions Authority Having Jursidiction, (AHJ) can use as a guide. There are products having a listing by a testing lab that can make the legal claim that the product complies to NSF 350. I will refrain from making a commercial announcement about names. Suffice to say, over $5000. is a beginning point for price.
