When the Portland Water District procured the Portland Water Company one of its first goals was to increase the amount and pressure of the water it was responsible for delivering. To achieve this goal the Portland Water District decided to lay additional lines from Sebago Lake to Portland.

For this project District trustees hired New York engineer Allen Hazen, contracted the United States Cast Iron Pipe and Foundry Company of Philadelphia to provide 42" cast iron pipe and specials, and employed John C. Tierney, of Hoboken New Jersey, for hauling and laying the pipe and fittings. In approximately one year the new transmission line was completed.
