Stormwater Management

Stormwater Drainage System

Gwinnett County Department of Water Resources is responsible for managing and maintaining the storm drainage systems in the City of Lilburn. 

Report a water pollution or stormwater issue.

To report a water service interruption or sewer service overflow, contact the Gwinnett County Dispatch Center at 678-376-7000 for immediate assistance.

Detention/Retention Pond Maintenance

According to the City of Lilburn development regulations, it is the responsibility of the property owner to maintain a detention pond. That could be a homeowners’ association (HOA) with a detention pond on a common parcel. If there is no HOA, the responsibility for maintenance falls on the owner(s) of the property on which the pond lies. Organized neighborhood work days at the detention pond by the owner and residents can be very effective in preventing expensive repairs.

Industrial Stormwater Education for Businesses

Business Education 1: Preventative Maintenance

For many businesses in Gwinnett it’s a lot easier to prevent a mess than it is to clean it up. Preventative maintenance involves inspecting, maintaining, and testing equipment and systems regularly to spot any conditions that could potentially cause breakdowns or spills. It also involves finding sources for potential pollutants to escape, and having a plan in place to deal with any leaks that occur. Writing a preventative maintenance plan and training your staff will help keep preventative top-of-mind and protect our water resources.  

Business Education 2: Surface Cleaning

Keeping workspaces clean at our businesses is an important part of watershed protection.  Indoor floors and the ground outside can occasionally require a wash, but the methods of cleaning these workspaces might introduce potential pollutants to the environment. Power washing can discharge harmful chemicals, as well as the grime on the surface such as oil, antifreeze, or grease, to the stormwater drainage system. This is why it’s important to avoid using soaps and solvents if possible, or be sure to collect and dispose of wastewater properly.  

Business Education 3: Non-Storm Water Discharges

Non-storm water discharges are any flows to local waterbodies that are not entirely made of stormwater. Gwinnett businesses can see if non-storm water discharges have occurred by noticing surface staining leading to a storm drain or seeing pools of water when it hasn’t rained in a while. If you notice any of these signs, you should work with your management to identify the source, implement remedial action, and develop a plan to prevent the discharge from occurring again. Storm drains lead directly to aquatic environments, so at your business be sure only rain goes down the drain.  

Business Education 4: Outdoor Material Management

Some materials at Gwinnett businesses must be kept outdoors. However, this can make them susceptible to becoming a pollutant in the environment. Covering outdoor storage will not only protect the environment but also the items being stored. Use a tarp or shrink wrap to protect materials. Put the material on a pallet to keep it off the ground or store it in secondary containment like double walled containers or shed. It is also important to keep all lids and caps on containers when not in use, store materials as far as possible from storm drain inlets, exercise care and planning when transferring items to minimize spills, and have spill-response materials ready to quickly mediate spills. 

Drainage Assistance/Rip Rap Program

Free to city residents, the City of Lilburn will deliver one truckload per year of drainage rocks. This is for erosion control purposes only, not for driveways or decoration. City public works staff will come out and assess the drainage situation and approve the delivery of rip-rap type III rock.
