The Delhi Charter Township Wastewater Treatment Plant is designed to treat a wastewater flow of 4.0 million gallons per day.

Primary treatment is accomplished through shredding, grit removal, and primary settling. 

Secondary treatment consists of activated sludge followed by secondary settling. The plant also has tertiary treatment that includes a nitrification tower and a polishing lagoon.

Disinfection is accomplished by chlorination of the nitrification tower effluent prior to flow through the polishing lagoon. Two additional lagoons are available for high flow storage or additional detention.

Dechlorination occurs naturally or is enhanced with Sodium Bisulfite treatment. 

Solids handling consists of a Class A anaerobic digestion combined heat and power system followed by gravity thickening and finally beneficial reuse through application to farm fields as fertilizer.

The Township Recycling Center is adjacent to the Wastewater Treatment Plant; plant personnel maintain the facility throughout the year.
