Mesa Water District owns and manages some 317 miles of water main pipelines. As the system ages, Mesa Water realizes substantial investments will be required to sustain its desired levels of service. With this in mind, Mesa Water conceived and completed a Master Plan in 2013 to assess the future of its pipeline system. Utilizing an age-based analysis, Mesa Water estimated that approximately $300 million of pipeline replacement would be needed over the next 30 years.

Over the years, Mesa Water pipelines have performed very well. The system experiences pipeline breaks at rates similar to other water systems in Southern California and approximately four times better than the national average. Therefore, even though some pipes have been operating for over 90 years, Mesa Water believes substantial portions of the system still has significant remaining useful life.

Guided by its Master Plan, Mesa Water District’s Board of Directors has set a policy to systematically assess the remaining useful life of its pipelines rather than replacing a pipeline solely based on age. This approach will save Mesa Water hundreds of millions of dollars in near term replacement expenditures by continuing to operate old pipe that is in good condition.

With engineering support from Michael Baker International and HDR, Mesa Water has developed an ongoing pipeline assessment program for its asbestos, cement, and ferrous pipelines. This program involves extensive system analysis, as well as non-destructive, and destructive testing to assist them to make accurate determinations of expected pipeline usefulness. In this way, Mesa Water can prioritize which pipelines need to be replaced based on remaining useful life.

By utilizing this meticulously conceived program, Mesa Water has been able to conserve capital resources by replacing pipelines only when they have deteriorated, not just because they reach a certain age.

Join us this month for an informative look at how Mesa Water and its engineering partners developed their innovative system of analysis. There are lessons aplenty to be learned from this highly successful program, and many practical applications for the technological advances developed in the creation of this cost-saving Master Plan.
