June 2021 – Project Completion, Griswold Water Purification Facility Raw Water Structure

Aurora, CO – We are proud to have completed Aurora Water’s Griswold Water Purification Facility Phase 2 Improvements.

This critical project relocated and enclosed the 42-inch Quincy Reservoir supply line and the 62-inch Rampart Range Reservoir supply line to accommodate concurrent valve operation for 0 to 120 million gallons per day. The project was delivered on an aggressive schedule. To ensure project certainty, JHL self-performed all underground wet utilities, above-ground bolted and welded steel piping, and select earthwork, structural concrete, shoring, and structural steel scopes of work.
