Anthropogenics is a modern term that applies to all major human impacts on the environment. Wastewater is one of the results. EETS engineers skillfully design controls and processes for effluent disinfection, pumping station rehabilitation, clarifier modification and SCADA instrumentation controls. All work meets or exceeds all regulatory guidelines.
