General Information

The Trenton Sewer Division is responsible for maintaining over 55 miles of sanitary sewer and about a half-mile of sanitary force main. The Sewer Division also maintains one lift station in town as well. The majority of sewer mains, laterals, and manholes are owned and maintained by City staff. Our sewage is fed via gravity sewer to a lift station on the south end of town that forces the sewerage under the Great Miami River to the LeSourdsville Waste Water Treatment Plant where it is then processed. The City contracts with the Butler County Sewer Department to process our waste.


The City takes a proactive approach with our maintenance program every year to help minimize backups and keep the wastewater flowing smoothly by performing the following tasks:

  • Inspect, clean, and camera about 4.5 miles of sewer main every year. Defects are pinpointed and repaired or replaced as needed.
  • Trained City staff inspect and test new pipe installations to ensure it has been installed properly according to City specifications.
  • Require connection to sewers if leach fields are found to be in use.
  • Immediate response to reported sewer backups.

Please contact a local, licensed plumber about having a sewer backflow prevention device installed in your home.
