McAlpine Creek Wastewater Treatment Plant

The largest of all Charlotte Mecklenburg Utilities wastewater treatment plants, the McAlpine Creek facility has a daily treatment capacity of 64 million gallons (though daily treatment averages much less than that). 

At each of our five wastewater treatment plants, State-certified wastewater treatment plant operators work 24 hours a day, 365 days per year -- constantly sampling, measuring and testing the wastewater to ensure its safety.

Over the last ten years, McAlpine Creek WWTP added more than $50 million in improvements to improve treatment processes and reduce the amount of phosphorus found in treated wastewater that is discharged into McAlpine Creek. This will result in better water quality downstream of the plant.

The plant is also home to the Charlotte-Mecklenburg Utilities Solids Residuals Facilities. This is where biosolids -- solid matter extracted during the treatment process --  are safely processed for recycling as fertilizer.  Biosolids recycling is a popular practice using a product that is rich in nutrients and beneficial to agricultural and landscaping operations. Biosolids are applied to area farms free of charge.

Nutrient Recovery Pilot Recycles Wastewater Nutrients As Fertilizer

The McAlpine Creek Wastewater Management Facility completed a pilot of a nutrient recovery technology that takes a “waste” and converts it to a useable product. The Ostara patented technology captures phosphorus and ammonia from the high strength water from the solids dewatering process. This water is recycled through a chemical process and converted to a natural fertilizer.

The fertilizer produced is a slow release, environmentally safe natural product in pellet form. Ostara has established a market for this fertilizer. Revenues from the sale of the fertilizer are shared with the treatment plant facilities to cover the cost of production facilities on site. In addition, the wastewater treatment plant would realize savings from not having to retreat the high strength water that is now currently recycled back in to the treatment process. This would reduce overall power and chemical costs experienced by the treatment plant as well as increase plant capacity and operational stability.

Ostara has full-scale operations in Durham County Oregon, Edmonton Canada and Hampton Roads Virginia. Pilots have been completed or are on
going in other cities as well. There were no outofpocket costs to do the McAlpine pilot, which was conducted June 2 through 10. Results of the pilot are currently being reviewed to determine the feasibility of a fullscale operation at McAlpine.
