Burgess & Niple (B&N) performed a field survey and prepared construction drawings and specifications to replace approximately 66,500 lineal feet (12.6 miles) of the City of Akron’s primary distribution main from its water treatment plant to its distribution system. The existing parallel 36- and 48-inch diameter steel water transmission force mains were replaced with new 48-inch Prestressed Concrete Cylinder Pipe (PCCP). B&N was involved in four phases of the project.
During Phase I of the replacement, the B&N team encountered petroleum-impacted soil and groundwater along a portion of the alignment. This prompted a subsurface environmental investigation, where B&N identified several potential sources of the petroleum product and redesigned the force main to prevent future contamination.
The project also included the design of 6,000 feet of 8- to 16-inch ductile iron water main, cleaning and cement-mortar lining of 4,600 feet of 48-inch cast iron water main, flow control chambers and maintenance of traffic.
