Introduction

Water in the western third of the United States continues to grow in scarcity and importance. States and communities are always looking for ways to conserve, as well as searching for new sources and innovative ways to re-use and recycle. A cost-benefit project to address this concern and need was developed in Colorado for one of the fastest growing cities in the United States.

The Prairie Waters Project was a $750 million, 5-year new construction, water transmission and treatment project for the city of Aurora, Colorado, scheduled to be completed in June of 2012. Nine simultaneously performed contracts collectively travelled 35 miles over several federal, state, county and city jurisdictions, and include 288 enrolled contractors covered through the Owner Controlled Insurance Program (OCIP). The project successfully and safely crossed a river, highways, railways, and private/public/protected lands, with both vertical and deep below-ground construction occurring. There were three intermediate pumping stations, a natural purification site with 18 wells, and a state-of-the art water purification facility constructed, tested and turned over to the city utility.
