We’re all aware that we are smack dab in the middle of an infrastructure crisis, and those in the know are constantly warning us that, without proper funding and implementation of large-scale repair and rehabilitation of our conveyance systems, we are all headed towards a water resource management Armageddon. There have been some high-profile examples of what can happen when water conveyance systems start to fail, including a series of water main breaks that peppered Los Angeles earlier this year.

But this week in Kalama, WA, I think we’ve finally found an example of exactly what a worst-case scenario looks like. The facts, as reported in The Seattle Times (http://seattletimes.nwsource.com/html/localnews/2010509308_apwakalamawater1stldwritethru.html), are as follows: On December 14, 2009 a frozen water main ruptured, resulting in a 15-foot gash and a complete draining of the municipal reservoir—over 1 million gallons lost. Adding insult to injury, the city’s other reservoir—which normally holds about 2 million gallons—is undergoing a series of repairs and is also empty. As a result, Kalama found itself completely bereft of a local water supply for several hours. Thanks to emergency measures, water service was restored to Kalama by the end of the day, but with all the attendant safety notices and boil-water alerts. Nevertheless, the Emergency Management Director for Cowlitz County, Grover Laseke, says it could take days to refill the reservoirs using wells in the area.
There’s no indication that anything other than the weather undermined Kalama’s water main, but be it Mother Nature, structural failures, or even sabotage, the result is the same: a broken pipe, a dry faucet, and a community without water. So what can Kalama, WA—population 2,000—teach us about water resource management and aging conveyance systems? Was this situation avoidable? Is the weather (and other environmental factors) a significant threat to existing pipelines and water mains, or are only aging or poorly maintained conveyance systems vulnerable? And was the situation in Kalama, two drained reservoirs, just an example of bad timing, or the canary in the gold mine, warning us all that our local supplies are always in jeopardy?
