New Wastewater Treatment Plant
Work was completed on our 5.2 million dollar wastewater treatment plant in 2017. The Plant replaced the aerated lagoon plant we had. The plant complies with the State ammonia nitrogen and disinfection limits allowed to be put into Little Bear Creek.
The new plant increased capacity from 500,000 gallons per day to 620,000 gallons per day.
Construction consisted of:
15" discharge line to creek, sewer splitter structures, a bypass to relieve the sanitary sewer main manhole, a duplex submersible lift station (200 gpm) with emergency generator, headworks facilities, in channel spiral screen and flow meter, grit chamber, main plant duplex lift station (500 gpm), equalization lift station (2250 gpm), activated sludge system, final clarifiers, and UV disinfection system.
The plant utilizes all 3 of the pre-existing lagoons. Two lagoons are used to store high flows during wet times of the year. This water is returned to the plant to be processed when flows entering the plant decrease.
The third lagoon is used for sludge storage, which utilizes aeration to keep the lagoon from having an offensive odor.
