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


Watersheds are areas of land that drain to a common body of water. What this means for businesses in Gwinnett is that any pollutants washed off your site during a rain event will combine with other pollutants from your watershed to possibly create a water quality problem in the waterbody. It isn’t just one discharge that leads to pollution, it’s the combined impact of multiple discharges within one watershed. This is why it is so important that each business in Gwinnett does its part to prevent stormwater pollution and protect water quality.

Good housekeeping

Just like a clean kitchen countertop prevents us from contaminating our dinner, a clean job site prevents pollutants from reaching our waterways. It is vital for businesses in Gwinnett to practice good housekeeping in the office, at the warehouse, or on the site to protect water quality. Good housekeeping involves proper storage and cleanup of materials used for daily activities, as well as establishing effective maintenance and inspection procedures for equipment and employee training. Keeping your business location clean and tidy will lead to fewer discharges of pollutants and improved water quality of our surface waters.

Pollutant of concern

It could be bacteria, nutrients, sediment, heavy metals, or petroleum-based products in addition to many others. The pollutant of concern can be identified on the State of Ga’s 303(d) list of impaired waterbodies found at You may find that your business deals with materials that could contribute to this problem, which is why taking steps to prevent stormwater discharges is so important.  

Causes of stormwater pollution

Stormwater is like nature’s shower for the environment. Whatever is on the ground when it rains, will wash away with the runoff and eventually reach a stream or river. At a business, there is a distinct possibility for pollutant sot be on the ground. Whether that is motor oil at an auto repair shop, paint near a hardware store, fertilizer at a plant nursery, or soapy water at a car wash, anything other than rainwater entering our waterways is considered pollution. Be sure to practice good housekeeping at work, train your staff to know ow to respond to spills and leaks, and perform self-inspections of your business to identify any possible sources of pollution. The benefits will be a clean and healthy environment for all Gwinnett residents and businesses to enjoy.
