Like many expanding suburbs, Camas, Washington (U.S.A.), faced the problem of updating its aging sewage collection system to meet the needs of the city's growing population. Located on the north bank of the Columbia River, adjacent to Portland, Oregon, and Vancouver, Washington, this ecologically sensitive town couldn't risk any kind of sewage backup if the local electric utility failed. To increase reliability and safety, the city specified that each new lift station include a standby power generator from Cummins Power Generation.

Camas city engineers set several requirements when they began replacing the lift stations. Reliability, easy maintenance and consistency of design and performance were top of the list. Each lift station is pre-engineered by Romtec Utilities of Roseburg, Oregon, to meet those requirements. All components, including structural, mechanical, electrical, power generation and communications, are pre-engineered, delivered as one package and installed in about a week.

"We chose Cummins Power Generation for the same reason cities choose us," said Mark Sheldon, , Romtec Utilities' VP of marketing and sales. "They receive our requirements and respond quickly with the right generator set and transfer switch, and they make installation and maintenance very easy."
