Sophisticated Sequencing of Water Transmission Main Repairs
The City of Richmond, Virginia (VA) is currently completing rehabilitation and/or replacement of two of the four existing transmission mains conveying treated drinking water from the water treatment plant to the water distribution system. The first transmission main is identified as the Treated Water Conduit. The Treated Water Conduit is a one mile long, 54 inch diameter cast-in-place concrete pipe with 50 million gallons per day (mgd) capacity and is being rehabilitated in some sections by installation of a 48 inch diameter steel slipliner and is being replaced in other sections with a 60 inch diameter ductile iron pipe. The second transmission main identified as the Korah 3 Main, is a five mile long, 36 inch diameter prestressed concrete cylinder pipe (PCCP) with 27 mgd capacity. Defective sections of this main are being replaced with 36 inch diameter ductile iron pipe. A three phase, four year project schedule was developed to complete the work in periods of low seasonal treated water demand and to comply with time of year limitations of environmental permits. Construction of two phases is complete. This paper discusses the details of the project construction schedule with emphasis on the phases of construction and sequencing.
