Del City WWTP upgrades project honored by ACEC of Oklahoma

With the City of Del City, Oklahoma in need of immediate upgrades to its aging wastewater treatment plant and processes, Garver’s expert Water Team not only answered the call, but did it so efficiently that officials saved $1.2 million.

Garver’s design of headworks upgrades, implementation of a new cloth media filtration process, and integration of a non-contact UV disinfection system (one of the first of its kind in the state) provided the most comprehensive upgrades to Del City’s WWTP in more than three decades. The project improvements and cost savings were so impactful to the future of Del City that the American Council of Engineering Companies of Oklahoma recently awarded it with an Engineering Excellence Award.

“To provide the city with the upgrades needed to continue serving their citizens, we assisted the WWTP staff by identifying work they could self-perform and assisting with prequalification of contractors. This promoted timely execution of the improvements and collaboration with the contractor and WWTP staff for cost-effective solutions to address unforeseen conditions,” said Garver Water Implementation Leader Kyle Kruger. “We’re proud to not only deliver these upgrades, but help the City save a sizable amount to address additional improvements without having to seek rate increases.”

Garver’s cost-saving recommendations included fitting the upgrades into the facility’s existing footprint, which prevented the City from having to purchase costly real estate for new structures. Careful design and construction sequencing of the headworks improvements kept the old facility online during construction. Cloth media filters replaced failing sand filters to improve effluent water quality and reduce size and energy requirements for the new non-contact UV disinfection system, which eliminated the need to complete annual risk assessments for use of hazardous chlorine gas.

The improvements provide the City with a state-of-the-art system to serve its residents for up to 25 years. And because of the savings, Garver helped the City identify the best use of the remaining loan funds.
