Gillette Madison Pipeline Project
In order to meet the water supply needs for the city and the surrounding area and provide for planned growth, Gillette hired Burns & McDonnell , and Morrison-Maierle as its sub-constractor, to develop the Gillette Madison Pipeline Project. It was awarded a Celebration of Partnerships award on May 31, 2017 in Gillette and the teams from Burns & McDonnell Morrison-Maierle were on hand to receive their awards.
Morrison-Maierle was responsible for the new Madison well field, in-town transmission loop, the in-town portion of the 42-inch transmission line, and all environmental and field work which represents approximately 40 percent of this $200 million project.
This project, which has two phases, addresses the need for a new water supply that was identified in Morrison-Maierle’s Long Term Water Supply, Level II Study. It creates a new well field adjoining the City of Gillette’s existing Madison well field, approximately 42 miles of 42-inch pipeline to get the water into Gillette, and associated pump station, reservoir, and regional service connections.
Morrison-Maierle’s contribution includes approximately 10 miles of 42-inch pipe; five miles of 36-inch pipe; one mile of 30-inch pipe; and ½ mile of 24-inch transmission piping to loop the pipeline around the southern end of Gillette and tie into the city’s water system at strategic locations. This project was completed on a very aggressive schedule to alleviate Gillette’s immediate water supply deficit and provide a secure water source for future connections throughout the region.
The in-town piping traverses a number of surface features including City of Gillette streets, Campbell County roads, WYDOT highways, open fields, utility-crowded rights-of-way, reclaimed mine land, and numerous utility, drainage, and overhead obstacles. To reduce cost and minimized disruption, a portion of the in-town piping has been constructed using horizontal directional drilling. Morrison-Maierle has coordinated and supervised the efforts of a local subconsultant to provide easement documents and legal descriptions.
