#PROJECTS: Doan Valley Regulators/Relief Sewers (DVRRS)

Rock Excavation

The Doan Valley Regulators/Relief Sewers (DVRRS) project is one part of Project Clean Lake, our 25-year program to meet Clean Water Act standards and address water quality issues related to combined sewer overflow pollution. The DVRRS is a part of the Doan Valley Storage Tunnel (DVT). The work includes new sewers and storm sewers, and new construction and modifications to several structures to control combined sewer overflows.

The DVRRS will be constructed on the east side of Cleveland. During construction, the DVRSS will have some short-term impacts on the community, including lane closures and traffic pattern changes (including bikeways), noise and vibration, dust, dirt, and/or mud, and disruption to community aesthetics. We will maintain updates here as provided by our project managers.
