Wastewater Treatment Plant Upgrades - Town of Dyer, Indiana

The Dyer Wastewater Treatment Plant required improvements to the coarse and fine screen equipment at the 2.6 million gallons per day (MGD) treatment plant.

NIES designed OSHA compliant improvements to the coarse screening maintenance cleaning operation, including new grating systems, and reworked coarse screen lifting system and handrails. Improvements will make the coarse screening maintenance operation cleaner and more efficient while enhancing overall safety. The 5 MGD static fine screens will be fitted with covers and a ventilation system for improved control of wastewater overspray and reduction of aerosols. The screenings washer compactor will be replaced with a unit of similar solids handling capacity but improved overflow and drain capacity to reduce frequent spills. Other improvements in the Grit and Screening Building include piping bolt replacements with stainless steel bolts, installation of a trench drain system, improvements to grit decanting containers to enhance drainage and reduce spills, and painting of piping, floors, walls, ceiling trusses and ceiling.
