Sewer Collection System Upgrade - MH GV1 to MH 1184 - 370015 - City of Frederick

Evaluate existing conditions and previous studies, conduct additional flow monitoring, design and construct an upgrade to alleviate the backup conditions and provide adequacy for future growth. Projected upgrade could be a 15"-18" sewer main crossing between MH 1186 and MH 1184, to reduce the burden on the existing 12" crossing of West Patrick Street. The manholes near 1350 W. Patrick Street have consistently overflowed during rain events with MH GV1 overflowing as recently as September 1, 2021. Engineering studies and modelling efforts, conducted through the Sewer Master Plan and APFO Development Reviews, have indicated that the mains in this area should be adequate to convey the dry weather flow for existing and future developments. However, conditions in the field indicate otherwise. An obvious restrictive factor in the area is one 12" main crossing West Patrick Street from MH 1185 to MH 1184. This crossing conveys all wastewater from the west and southwest basin, frequently from larger mains 15-18" in size. This project is in included in the City's or County's FY 2023-2028 Capital Improvement Plan (CIP). As of June 21, 2022, further details regarding design and construction have not been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change.
