AWWA EDC52010

As part of the City of Cleveland, Ohio, Division of Water (CWD) efforts toimprove its service, a decision was made to improve reliability, efficiency,control and reporting at the pump stations. About five years ago, the author wasgiven the privilege of spearheading the research, design and construction of awater pump station to test newer technologies and set the standard for the nextcentury's designs. This required a change in the manner Cleveland pumps water. Inother words, it required the designers to completely disregard the paradigmstraditionally dictating pump selection, control, instrumentation, etc. The term'resiliency engineering' has been recently used. This means that systems shouldbe engineered to operate within acceptable parameters for long periods of timewith minimum resource allocation after start-up. That is, a 'resilient system'bounces back and performs under less than optimal conditions such as those causedby lack of maintenance and change in operating conditions or customer demand.Although the authors were not aware of the term 'resiliency engineering' fiveyears ago, they inadvertently followed that philosophy because their research andinterviews of operations' personnel identified a need for such a design strategy.In researching the subject of pump station design, they acquired data fromtextbooks, articles, equipment manufacturers, other pump station designs,relevant equipment installations, standards, operational needs and requirements,and listened to operators and maintenance personnel's complaints. The result wasabout one hundred pages of dos and don'ts. Two pump stations have been designedand built using this recipe to date. A third pump station is presently underdesign. This paper discusses some of the lessons learned. Includes 13 references, figures.
