Welcome to the City of Helena Wastewater Treatment Facility
The City of Helena's Wastewater Treatment Facility (WWTF) uses a biological nutrient removal (BNR) process to treat over 1 billion gallons of wastewater each year.
Wastewater includes everything that goes down the drain. Such as showers, bath water, toilets, sinks, washing machines, dishwashers, discharge from local industrial cooling systems, cleaning projects, and some chemical processes. Over 178 miles of sanitary sewer pipes, 3404 manholes, and 5 liftstations throughout the City of Helena collect and transport the wastewater to the WWTF for treatment. The treated wastewater is discharged into Prickly Pear Creek which flows into Lake Helena and eventually to the Missouri River.
