McDowell Creek Wastewater Treatment Plant

Since McDowell Creek Wastewater Treatment Plant's opening in 1980, the plant has seen many changes. It has been upgraded twice to expand the plant's treatment capacity as demand has increased in the areas north of Charlotte. Recent upgrades increased McDowell's treatment capacity up to 12 million gallons per day.  This important expansion makes the McDowell plant one of the most technologically advanced in removing nutrients and enhancing downstream water quality.  The site also features 23 rain gardens to capture storm water, as well as sophisticated technology for providing high quality reclaimed water.

Because McDowell discharges into a waterway that has been identified as nutrient-sensitive, the plant uses biological nutrient removal as part of its treatment process. This advanced treatment technique includes removal of nitrogen and phosphorous from drinking water.

McDowell Creek WWTP Achieves ISO 14001 Certification

Charlotte‐Mecklenburg Utilities received notification last week that its certification to ISO 14001‐2004 has been extended to incorporate the McDowell Creek Wastewater Treatment Plant. ISO 14001‐2004 is an internationally recognized Environmental Management System. It provides a framework for demonstrating that good environmental management practices and required operational standards are consistently achieved. Certification comes as a result of an extensive five‐day external audit of our operations and maintenance programs with respect to potential environmental impacts. The corporate certification currently encompasses three areas of the Utilities Environmental Management Division: Mallard Creek Water Reclamation Facility, the Biosolids program and now the McDowell Creek Wastewater Treatment Plant.

These three substantial operating areas of Utilities–EMD have been certified in fewer than three years without significant external cost by using internal Utilities staff. Our goal is to continue to achieve certifications under the corporate certification umbrella at the other wastewater treatment plants over the next few years as resources allow. ISO requires demonstration of continuous improvement, utilization of staff at every level for ideas and a process approach. As a result of the implementation of the ISO program at our facilities, we have seen significant savings in operating costs totaling about $290,000 in a year.

ISO 14001 requires certification from an external certification (third party) authority. This standard is applicable to any organization that wishes to:

  • implement, maintain and improve an environmental management system
  • assure itself of its conformance with its own stated environmental policy
  • demonstrate conformance
  • ensure compliance with environmental laws and regulations
  • seek certification of its environmental management system by an external third party organization
  • make a self‐determination of conformance

The external audit was completed by AQA International who is an accredited and approved international certification company. AQA is accredited by the Independent Association of Accredited Registrars, which is an association of accredited management system registrars in North America.
