TCWWTP Expansion

The construction of the  $34 million Terrible Creek Waste Water Treatment expansion began in May 2016 allowing for treatment capacity to be increased from 1 to 3 million gallons per day.  The plant was officially placed into service in June 2018 with a public ribbon cutting ceremony in March 2019.

Where did the name Terrible Creek originate?  The earliest reference to a creek being named Terrible is on a map of Wake County dated 1886.

Capacity Expansion


The original treatment plant was constructed in 1997 with a capacity of 0.50 million gallons per day when the town's population was 6,800 and was expanded to 1.0 million gallons per day in 2001.  The current expansion project increases treatment capacity from 1 to 3 million gallons per day and provides treatment capacity in the Neuse River portion of town until at least 2034.  The Town Board authorized $34 million in revenue bonds to fund the project. The town's current population is 28,000 and is expected to approach 35,000 by the year 2020.

Features


The expanded plant includes a new influent pump station, pretreatment facility, biological nutrient removal tanks, secondary clarifiers, disk filters, ultraviolet disinfection, chemical storage and feed building, maintenance building, administrative building and a truck loading facility. The design of the plant allows for future expansion, should it be needed.

Hazen & Sawyer and Crowder Construction Company are the primary contractors for the project.
