摘要

In 2001, Metcalf & Eddy and the Sandwich Water District conducted a successful lining trial using rapid-setting polymeric lining material to determine if the material could prevent PCE from entering the water supply from factory produced vinyl lined asbestos cement (AC) water mains. The detailed results of this trial were published in the June 2003, Journal of the New England Water Works Association. This paper will expand on the lining trial to include the planning, design, and construction of the 8,500 linear foot vinyl lined AC water main relining project recently completed for the Sandwich Water District. The project is one of the first projects in the United States to use the spray applied rapid-setting polymeric lining material. The Sandwich lining project included development of a "same day return to service" procedure for newly lined water mains, which would allow up to 1,400 linear feet of water mains to be taken out of service, relined, and put back in service all within a 12 hour period. The same day return to service project would eliminate the need for overland bypass piping, which would ultimately result in a reduction to the overall project cost. To allow for the elimination of bypass piping, a successful public notification program and a stringent quality assurance program were developed to ensure a successful lining job. Although bypass piping was ultimately provided by the contractor, the programs developed for the same day return to service procedure contributed to a very successful lining project that proved to be a valuable test for these programs.
