Wastewater Compliance Evaluation

Coming in 2024, a new way to report sanitary sewer overflows through an online portal. Training and more information to be released in 2024.

Compliance evaluation for wastewater is responsible for receiving and logging bypass/overflow reports, administering the sewer ban program, and evaluating the compliance of wastewater treatment facilities with their NPDES permits, addressing instances of non-compliance, certification of wastewater facility operators and continuing education for operators.

For more information, contact the Office of Water Quality: (317) 605-6489.

Operator Assistance

The Operator Assistance Group within Wastewater Compliance provides operation and laboratory technical assistance to wastewater treatment plant (WWTP) operators and facilities. The objective of the 104-g-1 Technical Assistance Program is to assist small community wastewater treatment plants (less than 5.0 MGD) with NPDES compliance.

Our technical staff provides on-site, hands-on assistance in the proper operation of wastewater plants. Also, the technical staff provides management assistance and promotes the involvement of community elected officials in the operation of wastewater treatment plants. Please contact Aaron Deeter, or (317) 691-1915.

Laboratory Assistance

Laboratory technical assistance with NPDES approved test methods or other laboratory issues is available. Please contact Becky Ruark, or (317) 691-1909.
