Water Pollution Overview
The Solid Waste Division provides wastewater
treatment services at the Water Pollution Control Plant.
The Water Pollution Control (WPC) Plant began its existence in
1959 with the construction of Norfolk's first wastewater treatment
facility. At that time the City was generating 1.0 million gallons
of wastewater per day. The original plant included only preliminary
and primary treatment, and removed 50% of the pollutants. A
secondary treatment process was added in 1970 that raised treatment
efficiency to 95%. A general plant capacity expansion was completed
in 1980. A solids processing complex was added in 1990, and in 1995
a Sequential Batch Reactor (SBR) was added for nitrogen reduction.
The SBR removes 95-99 percent of the pollutants, including ammonia.
the plant's total hydraulic daily capacity increased to 7.1 (SBR is
5.74) million gallons per day and the peak capacity to 15.0 million
gallons per day with this project. An ultraviolet disinfection
process on the effluent was added in 2003, an influent debris screen
was added on influent in 2007 and grit wash system in 2014. We
currently receive 3.5 million gallons of wastewater per day.
The WPC Plant staff of 8.5 employees maintain the plant processes
and equipment, manage a solids application program, and conduct an
industrial wastewater monitoring program. Our laboratory conducts
daily treatment process monitoring tests, and discharge compliance
monitoring tests. We also provide testing services to neighboring
The performance of the plant is monitored by the Nebraska
Department of Environmental Quality, under regulations delegated to
it by the Environmental Protection Agency. Those regulations include
an NPDES permit that regulates the quality of water discharged to
the Elkhorn river.
