The Delhi Township Wastewater Treatment Plant (also known as the Publicly Owned Treatment Works) is designed to treat a wastewater flow of 4 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.

Leaf collection and disposal is important for the environment
Did you know? Residents should never allow yard waste to be washed down storm drains or dump grass clippings and leaves onto the street or in a roadside ditch.
Why?
Rain water that enters storm drains and roadside ditches eventually flows to a body of water without treatment, therefore leaves and grass clippings will eventually go with it.
The problem is that the nutrients in yard waste can lead to harmful algae growth in those bodies of water, including local creeks, ponds, or lakes. When leaves or grass clippings reach the water, they decompose, using up the oxygen in the water and killing fish and other aquatic life. This is the same water we use for fishing, swimming, boating, and recreation. Leaves that are left in the street can also block drains and cause flooding.
So disposing of yard waste properly helps you keep your yard tidy and also keeps our water clean.
