Glasgow WWTF Improvements
How did a rural community, challenged by tight budgets and limited staff, meet more stringent effluent standards and future nutrient reduction needs without constructing a mechanical wastewater treatment plant? They turned to Morrison-Maierle to develop an approach to ammonia reduction and disinfection improvements that maintained their simple-to-operate, lagoon-based approach to wastewater treatment. This facility, which became operational in late 2012, is now producing effluent of a quality that is exceeding all expectations.
Morrison-Maierle’s approach included a new screening facility, two covered, aerated lagoons, an aerated attached growth post-nitrification reactor, and a UV disinfection system. Morrison-Maierle helped the City of Glasgow secure approximately $2.5M in grant money for this $4.7M facility. In addition, they helped the City dispose of nearly 2,500 cubic yards of sludge from the existing lagoon and navigate through a year of delays with contractors and funding sources brought on by record flooding of the adjacent Milk River in 2011. Notably, the new facility requires no more operator attention or maintenance and produces remarkably better effluent quality than the former facility. A cost-effective and well-designed project, the improvements made to Glasgow’s WWTF will meet the City’s needs for years to come.
