The Pipeline is the approximately 15 km long water supply system that was used by the pulp and paper mill located in the city of Miramichi.
Even though the mill was located beside the Miramichi River, the salt content of the main branch of the river was too high for the paper making process so water had to be pumped from one of the tributaries. The Southwest Miramichi River in Bryenton was chosen as the location for the new pump house in 1965.
