Role:                      Project Manager, Project Engineer

                                                                                                                                Treated Water Storage at start of POM

Project Description:  Provided engineering analysis to determine the feasibility of replacing over 5 miles of existing 30-inch Techite treated water pipeline.  The existing Techite pipeline is extremely brittle and has resulted in numerous breaks in the line costing the district significant money to repair damages.  Challenges include keeping the existing pipeline on-line during construction, keeping construction a minimum of 15 feet from the existing pipeline to avoid breaking the line and the high pressures within the system. The pipeline is located in mountainous terrain with static pressure of over 300 psi.  Analysis included a cost estimate and alternative route analysis.  D&A is currently assisting the District with predesign services.
