Wastewater Treatment Plant Work Continues

In June 2022, the City of Dayton began construction of its new wastewater treatment

plant (WWTP) to replace the existing 50-year-old facility. The new WWTP will allow the

city to expand sewer services to our underserved communities and improve current

services. The City is being assisted in the WWTP design and construction oversight by

J.R. Wauford & Company, Consulting Engineers, with construction performed by

Reeves Young. The entire project is expected to be completed by the Summer/Fall of

2025 at an approximate construction cost of $40 million.


This project consists of the complete renovation of the existing WWTP and removal of

the existing Third Avenue Sewer Pump Station (SPS). A new Raw Wastewater

Pumping Station with Bar Screen, Headworks with Fine Screen and Grit Removal, Four

Basin Sequencing Batch Reactor (SBR) using fine bubble aeration, Blower/Electrical

Building, Effluent Pumping Station, Operations & Maintenance Building, Waste Sludge

Building, and conversion of the existing Aeration Basins and Clarifiers to effluent flow

equalization have been designed to upgrade the capacity of the WWTP to 4.0

Biological/15.0 MGD Peak. Permitting to allow the discharge of effluent flows above 5.5

MGD into the Tennessee River embayment using an existing force main which was

abandoned in place was necessary to allow for the increase in capacity. A new 24-inch

gravity sewer line is being constructed in order to eliminate the existing Third Avenue

SPS thereby allowing gravity flow to the new pumping station at the WWTP.
