Waukee, Iowa, is a quite suburb nestled just outside Des Moines. To
fill a need for aquatic recreation, therapy and competition, the
community partnered with the local YMCA.
In developing the facility, the design team applied several
innovative and eco-friendly features to reduce energy usage and
accommodate various age groups. Incorporated into the design was
reducing the building footprint and volume by selecting specific
pool heaters and a well thought out mechanical room layout plan.
Water’s Edge Aquatic Design engineers performed a cost
analysis to recognize the difference in costs between this forward
thinking design, versus traditional design tendencies.
Additionally, the selected regenerative media filters using a
perlite filter media can achieve water clarity equal to that of a
DE filter with less building footprint and less negative impact on
the environment and sewer systems.
As the primary heat source, the facility uses waste heat from the
dehumidification system and return it to heat the pool. A
supplementary heat source makes use of the Sentry Pool Heater that
uses a series of high efficiency heater units. The selection of
this recently developed pool heating system allows for reduced
energy usage as well as reduced maintenance and operation
Waters Edge Aquatic Design staff designed for the recirculation
pumps to operate at variable speeds based on the minimum flow rate.
Basically, the recirculation flows are automatically adjusted to
achieve a specified set point. The use of a Variable Frequency
Drive on the pump allows for the recirculation system to operate at
a minimum flow rate as opposed to operating a pump at full speed
and throttling a valve to achieve flow as is traditionally done.
This design allows for energy savings.
A low pressure UV system was selected to control harmful
chloramines that are detrimental to patron health as well as the
health of the building structure. The low pressure UV uses
substantially less energy than other types of UV systems currently
Low wattage overhead lighting fixtures were designed into the
project to reduce the electrical energy load of the facility.
The Waukee community and Waukee YMCA wished for a two pool concept.
The final concept was designed for the diversified audience and
multiple uses with the Waukee YMCA incorporating recreational
swimming, exercise classes, swimming lessons, competition swimming
and competition events. Special design considerations include a
learner’s platform for small children and ADA accessible
Overall costs were certainly taken into consideration.
Water’s Edge Aquatic Design staff used cast-in-place concrete
construction of the pool which provided better quality at a lower
cost than the alternatives. The equipment such as overhead light
fixtures, variable frequency drives on recirculation pump motors
and filters require less water wasted during regeneration compared
to more traditional filters. Design staff also reduced the pool
mechanical space to reduce future HVAC costs of the building.
This design has proved to be efficient and effective for the Waukee
community. Programming has been easy with the added amenities and
the three-pool concept design.
