Franklin Street Water Transmission Main

This $3.5 million mile-long, 30-inch, ductile iron water transmission main replacement project will be the backbone of the City of Auburn’s water distribution system for the next century. With an easterly connection to the 10.25 million gallon underground reservoir and a westerly connection to the primary transmission main and path to the City’s Swift Street Filtration Plant, combined with nine side-street interconnections, the City’s water supply is now far more sustainable, operable, and reliable.

During the design development phase, Erdman Anthony evaluated trenchless technologies, including slip-lining with fusible PVC and cure-in-place lining systems (Class III and IV), as well as full replacement. A design report documenting alternatives considered, construction cost, and environmental impacts was prepared in accordance with the state Department of Health (DOH) and the Environmental Facilities Corporation (EFC) procedures and guidelines for projects funded by the Drinking Water State Revolving Fund; the DOH/EFC State Environmental Review Process; and the State Environmental Quality Review Act, 6NYCRR Part 617. An Engineering Report was also prepared that included project plans and specifications. It was submitted to the DOH and the Cayuga County Health Department for review and approval.

The new 30-inch ductile iron water transmission main replaced a deteriorating (vintage 1933) 30-inch steel main and serves a population of approximately 45,000. The service area includes not only the City of Auburn, but also the neighboring townships of Sennett, Throop, Brutus, Montezuma, Springport, and Aurelius, as well as the villages of Port Byron and Weedsport, the Cayuga County Water Authority, and the New York State Thruway.

Erdman Anthony prepared plans, specifications, and bid documents. Plans and specifications included push-on and mechanical joint pipe as well as restrained joint pipe systems. Valve types included gate valves for smaller water mains and butterfly valves for 16-inch and larger piping. Other water-supply-related appurtenances provided included hydrants, new water services to replace old galvanized and lead piping, and 6” to 12” water main piping to establish the side-street interconnections.

Critical to the success of the construction phase, and unique to this water transmission main project, a highly detailed installation sequence was required to allow for uninterrupted water supply and replenishment of the Franklin Street reservoir. Erdman Anthony developed an eight-stage installation sequencing plan, which was reviewed by the City of Auburn and successfully executed by the contractor.

During procurement of the project, Erdman Anthony was responsible for conducting the pre-bid meeting, preparing bid tabulations, checking contractors’ references, and making the recommendation for award. Erdman Anthony also provided construction-phase engineering, full-time resident engineering, construction inspection services, and management of geotechnical testing services. In the last capacity, Erdman Anthony provided engineering reports and engineering certifications to the City of Auburn and the Cayuga County Health Department.
