    • The cost of this project involved more than just new pipeline. In addition to approximately 2,120 linear feet of 8-inch ductile iron pipe (which requires not just the piping, but also pipe bedding, trenching / backfill, full slurry seal, surface restoration, and decommissioning the old line), we also installed 6 fire hydrant assemblies, 1 combination air/vac valve assembly, and replaced 48 service connections. The best news is, the cost of this project came in under the original estimate by more than $200k: its final construction cost of $521,763.19 included all of the above scope—from design, permitting, and construction administration, to construction and final inspection.
