Nall Avenue Pump Station - Completed Fall 2012

Leawood is a community of attractive neighborhoods and upscale shopping. What it needed was some pressure. Leawood is located more than 10 miles from WaterOne's nearest treatment facility. As the community prospered, the growth challenged the ability of the water system to meet the demand, causing residents to occasionally experience lower water pressure during periods of high demand.

Anticipating the growth in its southeast territory, WaterOne planned ahead for a new pumping station and reservoir in its Master Plan. The facility would provide the extra capacity and additional muscle needed to push water to the service area.

WaterOne and its engineering partner Burns and McDonnell worked with the City of Leawood to influence the design of the facility, located near the intersection of 143rd Street and Nall Avenue. The project buried a 6 million gallon reservoir safely beneath a rolling green knoll. An attractive brick pumping station with ironwork detail is bermed into the reservoir hillside to blend in with the surrounding neighborhood that borders Leawood and Overland Park.

More than 600 trees, bushes and ornamentals were planted on the site. A bio-retention area handles site run-off, featuring nearly 1,400 plantings. The ground over the reservoir is the size of two football fields of nearly flat grassed area, a neighborhood amenity.

The project ensures a minimum pressure of 40 pounds per square inch (psi) during peak demands and typical minimum pressures of 70-90 psi during other times. Moreover, Leawood's fire rating is safe-guarded by improved flows and sustained capacity for fire suppression, ensuring safety and supply into the future.

Community Dedication

When WaterOne marked the project's completion in November 2012 with a community dedication, it was clear why the Nall Avenue Pumping Station and Reservoir is noteworthy. Over 120 people turned out to admire the new facility, including WaterOne's Governing Board, city and Chamber officials, local residents, and project team members from Burns and McDonnell, CAS Construction, and WaterOne.

The Nall Pump Station brought together a water provider and its engineering partner with local leaders to address the community's needs, meet its standards, and create a lasting statement of excellence.
