Project Description

The Old Highway 40 Conveyance Project included the installation of three parallel water pipelines along the edge of Old Highway 40. The 42-inch HDPE raw waterline is 2492 lineal feet and ties into the upper Provo River to carry raw water to the future treatment plant. The 24-inch DIP snow making water line will pump water from the treatment plant. The 16-inch DIP pipe will carry finish treated water from the treatment plant. A concrete vault over the finish water and snowmaking lines containing air valves and butterfly valves will also be installed. The pipeline paralleled a 138kV transmission power line that required safe distance procedures and coordination with the power company to hold power poles when crossing to tie-in. The entire project has a high-water table that had to be dewatered during installation. The DI pipelines were coated for cathodic protection which required extra careful handing when off loaded and when installed.

Unique Problem Solved

COP was able to recycle all the excavated aggregates by crushing and processing for all the projects stabilization rock, bedding sand, and A1a backfill. Old Highway 40 had to be reduced to one lane with alternating traffic throughout the entire project while maintaining access to the campground nearby.
