CH2M provides operations, maintenance and management services for municipal and industrial clients’ facilities.

Facility successes

Our clients’ wastewater treatment facilities discharge to a variety of water bodies. Standard National Pollutant Discharge Elimination System (NPDES) permits require that 85 percent of all biochemical oxygen demand and total suspended solids are removed in the treatment process to protect water quality in receiving streams. We bring value to our clients and water resources by achieving removals above national standards at the 74 client water resource recovery facilities we manage throughout North America.

In collaboration with our clients, we operate treatment plants aligned with their management and budget objectives and deliver global best-practice innovations in these local facilities.
