Sewall has assisted the Pleasant Point Passamaquoddy Tribe with multiple waste water projects including the replacement several thousand feet of sewer main, three submersible sewerage pump stations, and the partial reconstruction of two additional pump stations.
The projects included construction of three masonry pump station buildings, a concrete retaining wall, installation of gravity sewer main and force main, installation of dual self priming suction lift pumps, and installation of back-up power generators. Projects also included a design to abandon an additional pump station, thereby eliminating the associated maintenance and on-going utility costs.
Sewall services included topographic survey, construction level design, bidding services, full-time construction inspection, and construction administration.
