About the Whitefish Nereda® WWTP

Whitefish is located in the western part of the state of Montana and is surrounded by many outdoor recreational areas. The Whitefish Mountain Resort in the Rocky Mountains is one of the top 25 ski locations in the world, and the Glacier National park, home to Whitefish lake, is a popular hiking destination in the summer.

The challenge

The former Whitefish WWTP was issued an administrative order to improve its wastewater treatment process in order to become compliant with the new requirements for nutrient removal. Being a resort town, the Whitefish WWTP was also suffering from seasonal spikes and needed to increase its treatment capacity. 

The solution

In 2018, the city of Whitefish chose Nereda technology for its new and upgraded wastewater treatment plant. Nereda was chosen due to its small footprint, reduced energy consumption and lower CAPEX and OPEX. Due to a lack of clarifiers and greatly reduced process volume, the total installed cost for the Nereda technology was considerably reduced compared to other evaluated processes. Another advantageous aspect of the Nereda process is the fact that it operates robustly and efficiently in wide temperature ranges, allowing for regulatory compliance at lower operational costs throughout the cold winters in Montana. 

The outcome

The construction of the Whitefish WWTP was completed in the summer of 2021 and the plant went into operation shortly after. The current plant is treating a municipal effluent load of 34,600 p.e. with a daily average flow of 9,245 m³/a day and a peak flow of 1,094 m³/hour. The new plant enables Whitefish to achieve regulatory compliance, while reducing its operational cost.
