Backflow and Fireflow Improvements
DJ&A was responsible for the survey, design, and construction management for the sewer main replacement to better suit the needs of the growing elementary school district in Dillon, MT.  The Parkview Elementary School and the Dillon Middle School currently are connected to an existing 8 inch sewer collection system main just west of Cottom Drive in the alley.  The 6 inch diameter service lines were very flat (0.015% to 0. 030%) causing the schools two sewer service lines to continually plug. 

The school's serve 615 students and 52 teachers.  The school district is currently constructing an addition between the two schools to include a library, gym, administration offices and 12 additional classrooms for the elementary school.  The addition to Parkview Elementary School will serve 93 additional students and teachers.  To address this need and future growth, DJ&A designed an 8-inch sewer main.
