Treatment at New Depths

Freese and Nichols truly dug deep when Dallas Water Utilities needed a new influent pump station. The team challenged the industry mindset of wastewater pump station design, emerging with an innovative facility that cost 30 percent less than traditional designs. With six vertical turbine solids handling pumps — the deepest-set in the nation, at 62 feet — in two trench-type wet wells, the pump station achieves wider ranges of flows than centrifugal pumps and has all maintenance activities accessible at ground level. Throughout design and construction, there was only one change order, about 0.6 percent on a $49 million project.
