Surface Water Quality

Pollution Control​ Program​

The Pollution Control Program installs, retrofits, and maintains stormwater control measures (SCMs) to reduce pollution and the volume and velocity of stormwater in developed watersheds where streams are degraded. This degradation has largely resulted from the impacts of historical stormwater management practices prior to current water quality rules and practices, and the impacts from urbanization. The Pollution Control Program aims to improve these watersheds by installing new SCMs where they will remove the most pollution or increasing the efficiency of previously installed SCMs so they remove more pollution than originally designed.

Examples of SCM retrofit projects include wet ponds. When stormwater enters a pond, it slows down and nutrients and sediment settle out before the water enters a local stream. Every year, the Pollution Control Program evaluates and ranks existing wet ponds within the City of Charlotte to determine how much stormwater pollution could be reduced if they were retrofitted and maintained by the City. Ponds are ranked based on a number of parameters including dam condition, capacity for removing pollutants, cost-effectiveness and willingness of a landowner(s) to donate easements.
