Plummer designed the original 0.68 million gallons per day (mgd) Denton Creek Regional Wastewater System wastewater treatment plant, followed by expansions to 2.5 mgd, 5 mgd, and 11.5 mgd over the following decades. The original plant consisted of a primary clarifier, conventional activated sludge basins, rectangular final clarifiers, effluent filters, and the first UV disinfection system in Texas.

In the expansion to 2.5 mgd, the primary clarifier was converted to a sludge holding basin and a sequencing batch reactor was added to provide treatment for the periodic high flows from the Texas Motor Speedway race events.

Additional sequencing batch reactors and cloth filters were added in the expansion to 5 mgd and the UV system was rehabilitated and expanded. The expansion to 5 mgd also included a Tier II Clean Water SRF Environmental Assessment.

A solids management expansion incorporated a new sludge dewatering building with a centrifuge to replace the existing belt filter press. This solids management project also included a 1.5 million gallon peak flow storage basin.

For the expansion to 11.5 MGD, Plummer designed a new 5.0 mgd treatment train with biological nutrient removal using a modified University of Cape Town (UCT) process. The existing aeration tanks and final clarifiers were converted to the UCT process, and new circular final clarifiers were constructed to expand the capacity of the existing plant to 6.5 MGD. The project included a new influent pump station, influent screening, grit removal, cloth media filtration and UV disinfection. The sludge process includes aerated sludge holding tanks for waste activated sludge (WAS) and centrifuges for dewatering.
