Manufacturing facilities consume substantial quantities of water, energy and chemicals and frequently exceed sanitary sewer limits for pH, Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), Oil and Grease (O&G), and/or metals emissions.

Enviro-Stewards preferred approach is to first reduce toxic usage and utility consumption at source and then (if still necessary) to design appropriate pre-treatment facilities treat any remaining concerns (see case study video at right).

Enviro-Stewards work in the manufacturing sector includes:
