The Delhi Charter Township Wastewater Treatment Plant is designed to treat a wastewater flow of 2.5 million gallons per day. Primary treatment is accomplished through shredding, grit removal, and primary settling. 

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

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 anaerobic digestion followed by gravity thickening and finally beneficial reuse through application to farm fields as fertilizer.

The Maintenance/Safety division of the Public Services Department provides a wide variety of maintenance tasks to the Township infrastructure, buildings and grounds, cemeteries and vehicles. The department also provides support for the DDA (Downtown Development Authority) to keep our downtown area clean and colorful.

The Maintenance/Safety department answers calls for sewage back-ups in those areas served by sanitary sewers. The department also has equipment to clean and inspect our main lines in the public right-of-way and roads.

If you experience a problem with your sewer, you can receive a response by calling 694-9231 (24) hours a day.  Please do not use email for sewer emergencies.  This phone number is the only contact for 24 hour response.

Delhi Charter Township has a safety committee that oversees the day-to-day safety of our employees. The Superintendent of Maintenance / Safety Coordinator and his staff are responsible for programs and training to comply with State and Federal law. 

You may have noticed this department working in the street or manholes with something that looks like futuristic equipment. This is required to enter what we call confined spaces.
