Creative Cost-Savings

Officials in Del City, Oklahoma are enjoying all the benefits of an upgraded wastewater treatment plant, complete with new infrastructure for the first time in over 30 years. And thanks to Garver’s Water Team, the City saved more than $1.2 million of its Clean Water State Revolving Fund loan.

To address an aging WWTP that was having trouble meeting permit requirements, Garver designed new headworks and grit removal facilities, rehabilitated sequencing batch reactors (SBRs), replaced a sand filter unit with a new cloth filter, and implemented one of the state’s first non-contact UV disinfection systems in lieu of chlorine disinfection.

“The state-of-the-art non-contact UV system provides the operations staff a safe and reliable disinfection solution with significantly less O&M while also using an existing building,” said Water Implementation Leader Kyle Kruger.

Garver’s recommendation to fit the upgrades into the facility’s existing footprint saved City officials from having to purchase costly real estate and build new structures, and maximized existing systems by keeping the headworks system online during construction.

The $1.24 million in cost savings allowed the City to purchase much-needed additional equipment for improved operations.
