City of Blackfoot Sewer Department

About Sewer Department

Plant Design

The City of Blackfoot Treatment Plant is designed to treat 3.2 MGD with a peak flow of 5.1 MGD. Our average volume treated in 2014 was 1.65 million gallons. Conveying the wastewater to the plant is 74 miles of pipes. On a daily basis the treatment plant removes 99% percent of BOD, 97% of TSS, and 90% of Phosphorus. The plant is located at 2025 Riverton Road in Blackfoot. A facility plan conducted in October 2013 details the facilities current shortcomings as well as future upgrades.

Department Staff

Thirteen men and women are employed by the Sewer Department. There are four plant operators, four collection system operators, two maintenance people, one pretreatment coordinator, one lab manager, and the Superintendent.

Laboratory

Our lab works to ensure that the plant processes are monitored, that the effluent is within permitted limits, and samples brought in from outside the plant. Some of the procedures used in the laboratory are: BOD5, COD, TSS, pH, Total Phosphorus, Total Ammonia, among others. The lab is managed by one Lab Manager, who works five days a week.

Pretreatment

The City’s Pretreatment program was approved in 1986 by the USEPA. The Pretreatment program aims to help ensure that the wastes generated in the City are safe for the collection system, workers, and is within a treatable range for the treatment plants processes. This is accomplished by inspection, monitoring, and educating industry, businesses, and residents of their role in protecting our waterways.
