Mill Creek WWTP High-Rate Treatment Facility



Project Overview

This project is anticipated to be a Progressive Design-Build project to design and construct a new 400 MGD High-Rate Treatment Facility at the Mill Creek Wastewater Treatment Plant (WWTP)in the Cincinnati neighborhood of Lower Price Hill/Queensgate. This project is the third phase of a multi-phase series of projects that will allow for peak wet weather flows of 700 MGD to be handled at the WWTP. This is the second step of construction necessary to construct the future wet weather facility.


The HRT facility is expected to be located in the lot south of the existing treatment plant (on the south side of Gest Street). According to existing geotechnical data, the HRT will need to be constructed on piles due to the weak native soils. Extensive dewatering will also be required, and contaminated soil may be encountered during excavation for the HRT.
