NOWTS definition
NOWTS means a non-conventional OWTS. It provides additional treatment of the effluent to reduce Nitrogen (N), Total Suspended Solids (TSS), and the Biological Oxygen Demand (BOD). It may also provide disinfection against pathogens, and alternate methods of effluent dispersal. NOWTS corresponds to the Tier 3 OWTS described in the OWTS Policy and any OWTS with a requirement for supplemental treatment.
