For wastewater treatment forms, please visit our forms page.
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, 3470 manholes, and 7 lift stations 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.
If you would like to learn more about the wastewater treatment process feel free to contact us at (406) 457-8558.
Industrial Pretreatment Program
The City of Helena has an approved Industrial Pretreatment program that is regulated by the EPA and used to maintain compliance with the Wastewater Treatment Facility's discharge permit requirements. This program facilitates compliance by reducing heavy metals and other harmful contaminants from entering the WWTF.
The Wastewater Treatment Facility continues to accept hauled septic waste as a valuable community service. Licensed Septic haulers are required to complete a Manifest Form (please see our forms page). for every load dumped at the designated dumping station.
If you are discharging anything other than normal household waste into the sanitary sewer you must fill out an Industrial User's Application (please see our forms page).
