proHNS deftly designed this complicated utility and drainage improvement project, which will replace multiple underground water transmission and distribution pipe networks with new 10” and 14” HDPE pipe, water services, and hydrants. Work will also include installation of temporary water systems to maintain service to the high pressure transmission network between PRVs, and temporary water systems to maintain service to affected residents; replacement of the existing sewer systems; replacement of an existing CMP culvert and concrete headwalls with a new 84” diameter x 130’ long SRPE pipe culvert and new concrete headwalls; a new underground storm drain system; and grading and shaping of the existing unpaved road’s surface and resurfacing with RAP material. proHNS also administered and inspected this project on behalf of CBJ over the course of the Summer 2021 construction season.
