Image Info

This pipe laying machine was used in the 1922 waterworks project that connected the city of Portland's water supply with that of South Portland's, to improve water service to South Portland.

This project was considered to be at the cutting edge of engineering technology at the time. All of the preparation for connecting each section of pipe was done above ground whereas in previous submarine projects divers had to caulk each section of pipe underwater.
