As part of the City of Cleveland, Ohio, Division of Water (CWD) efforts to
improve its service, a decision was made to improve reliability, efficiency,
control and reporting at the pump stations. About five years ago, the author was
given the privilege of spearheading the research, design and construction of a
water pump station to test newer technologies and set the standard for the next
century's designs. This required a change in the manner Cleveland pumps water. In
other words, it required the designers to completely disregard the paradigms
traditionally dictating pump selection, control, instrumentation, etc. The term
'resiliency engineering' has been recently used. This means that systems should
be engineered to operate within acceptable parameters for long periods of time
with minimum resource allocation after start-up. That is, a 'resilient system'
bounces back and performs under less than optimal conditions such as those caused
by lack of maintenance and change in operating conditions or customer demand.
Although the authors were not aware of the term 'resiliency engineering' five
years ago, they inadvertently followed that philosophy because their research and
interviews of operations' personnel identified a need for such a design strategy.
In researching the subject of pump station design, they acquired data from
textbooks, 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 was
about one hundred pages of dos and don'ts. Two pump stations have been designed
and built using this recipe to date. A third pump station is presently under
design. This paper discusses some of the lessons learned. Includes 13 references, figures.
