Brick Pond Park is a forty acre restored wetland that functions as a stormwater treatment system. It was developed to remove pollutants from stormwater runoff in the ponds and to improve the ecosystem. Before we started restoration, the system was disconnected and it had little to no dissolved oxygen in the water. The ponds were full of excessive nutrients, trash, industrial debris, and dead/dying trees. There wasn't very much wetland vegetation either. Aquatic species were nearly non-existent, but semi-aquatic species like amphibians and reptiles were still present throughout the system.

water lilyNorth Augusta and the developer(s) of Hammond's Ferry partnered together to determine what could be done to solve this issue. We designed and implemented a plan to improve the ecosystem and create the Brick Pond Park. Through early studies it was found that several elements of a healthy ecosystem were missing that needed to be provided to successfully restore the ecosystem. Also, this would help provide a way to clean the stormwater before it entered the river. These elements included dissolved oxygen, water movement, a connected system, diverse aquatic species, and a variety of plants.  The incoming sources of excessive nutrients needed to be identified and eliminated to improve water quality. Our teams worked to fix these problems. The ponds were connected to one another by removing berms that had been present for decades. Waterfalls and pumps were installed near the constructed wetland to provide movement and aeration to increase dissolved oxygen levels. Plants were selected and placed in specific locations to remove  pollutants coming into the system with rain water from roadways, yards, parking lots and garden areas.  

Trash, sediment, and other pollutants that are brought in through stormwater pipes are filtered-out of the system by using the wetlands that already existed higher on the landscape at the park.  These existing, perched wetlands were planted with vegetation and the stormwater was routed to them first. The perched wetlands now act as pre-treatment wetlands and are located adjacent to the constructed wetlands. Once the water is pre-cleaned and reaches the constructed portion, it is filtered again by plants and other biological processes. The clean water is recirculated continuously back through the system by the waterfalls. 

To prove the system works, water samples are taken at several locations such as where water enters from storm drains, within the perched wetlands, beyond the constructed wetland, and within the ponds. The sample results continue to indicate that the system is removing pollutants as designed. Other indicators like the improvements in wildlife use, wetland plant colonization, and aquatic species colonization show improved overall water quality at Brick Pond Park. Today the wetlands within the park are much healthier than before and can sustain the abundant wildlife that is required to maintain a healthy wetland ecosystem.
