Tigard, Oregon enhanced their technology and business process improvement in order to prepare for a newly constructed $164 million water system source. Due to changing water chemistry, the city needed to clean approximately 227 miles of water distribution piping. Using technologies like a computerized maintenance management system (CMMS) with geographical information system (GIS) connectivity, and a computerized water hydraulic model, the city developed and completed an efficient and effective "Uni-Directional Flushing" (UDF) program. The use of different technologies helped plan and manage the program, including work planning, performance benchmarking, and project tracking. The city was under deadline to complete the flushing program prior to delivery of water from the new system in order to ensure high water quality.
