Clark Creek WWTF Improvements Phase I

The Clark Creek Wastewater Treatment Facility Improvements project is a comprehensive upgrade to critical treatment infrastructure, expanding capacity from 5 mgd to 7.5 mgd while modernizing aging systems for long-term reliability.

At the center of the work is a new influent pump station, a 40-foot-deep concrete structure requiring 980 cubic yards of concrete, built to house vertical turbine solids handling pumps and dual mechanical screening equipment. Crews completed controlled rock blasting once excavation neared bedrock ­­– all of it carried out within a live, operating treatment facility.

The project also delivers an upgraded grit removal system with a Parshall flume, a new liquid lime storage and feed system, a septage acceptance plant with receiving pump station, and a plant-wide SCADA upgrade that gives operators better visibility and control over daily operations.

Beyond the new facilities, PC Construction is improving the existing secondary clarifier and chlorine contact basin, and completing extensive site work, yard piping, and electrical upgrades throughout the plant.

The expanded and modernized Clark Creek facility will give Newton the capacity and reliability it needs to serve residents and businesses well into the future, all while continuing to protect water quality in Clark Creek and the broader Catawba River Basin.
