A brief description of the services sought:
This RFQ is for design of a Wet Weather Improvement Plan (WWIP) stormwater separation project. The proposed Mt Washington Source Control Implementation project will remove street inlet storm flow from the combined sewer and convey it to the downstream combined sewer at a location where capacity exists to accept the flow. A total of 60 properties are impacted in the neighborhood, including 46 sewer backups (SBU) by three extreme weather events in 2011, 2012 and 2016. The sewer backups occurred on Mayland Drive, Lusanne Terrace and Woodlark Drive in Mt. Washington.
The preferred engineering approach for the project is to separate storm flow from combined sewer. Portions of the new storm sewers will be oversized to provide in-line storage with a controlled outlet. The proposed new storm sewer will connect to the existing combined sewer. Most of the work will occur within the public right-of-way; however, installation of sewer assets on private property may occur.
A business case evaluation (BCE) for this project was developed and it recommends to construct 1,710 linear feet of new storm sewers ranging in size from 30-inch to 42-inch diameter and 750 linear feet of 6-foot by 3-foot box culvert.
