Stormwater runoff is rainwater that flows across the land and is routed through our stormwater drainage systems into creeks, lakes and wetlands. Urbanization reduces the amount of water that can be absorbed into the ground through the increase of impervious or hard surfaces such as roads, driveways, sidewalks, walkways and patios and roofs. The impervious surfaces increase the amount of stormwater runoff flowing overland that, if left uncontrolled, could result in increased risks to flooding, erosion, watercourse health and aquatic life.
The purpose of a municipal stormwater system is to collect, convey and discharge stormwater runoff to the natural environment.
A municipal stormwater system typically consists of service connection pipes (only allowed in limited areas in the County), catchbasins, mainline sewers, manholes, culverts and stormwater management ponds.
The County of Brant stormwater systems are located throughout the County with the largest systems being in the community of Paris, St. George and Cainsville.
| Culverts |
| A stormwater culvert is a structure that allows water to be conveyed under a road, entrance, or similar obstruction. Culverts are not permitted to be installed to facilitate the installation of piping (i.e. irrigation piping) under a municipal roadway.
If you are contemplating installing or altering an entrance to your property and roadside ditches exist along the municipal roadway where the entrance will be located, you will need to complete a Public Works Permit Application (and pay applicable fees) which will require a culvert to be installed, along with other requirements. |
| Storm Sewers |
|
It is necessary to regulate the discharge of materials to municipal and private storm sewer systems and to protect water quality by preventing the discharge of harmful substances to municipal and private storm sewer systems and, ultimately, to water bodies within the County. Discharges that do not meet the requirements outlined in the Storm Sewer Use By-law could have serious consequences for public health and safety, municipal infrastructure, and the environment. Even if the discharge is very small in quantity, the total combined effect can be significant. Unauthorized discharges could result in:

| Storm Sewers Connections |
| A stormwater service connection connects a private property to the municipal stormwater system. Typically, for new developments, the property owner is required to design and construct their private stormwater system (located on their property) to meet pre to post quantity control and applicable quality controls.
Stormwater service connections for individual residential properties are only allowed under special circumstances and must be approved by the County. |
| Stormwater Management Ponds |
|
To manage the increased risks to flooding, erosion, watercourse health and aquatic life caused by stormwater runoff, the County often requires developers to construct stormwater management ponds to control stormwater runoff from their subdivisions. Upon assumption of the development, the County starts maintaining the stormwater management ponds. The County of Brant maintains 23 stormwater management ponds located in the communities of Paris, St. George, Burford, Oakland and Scotland. The County's role in the pond maintenance includes:
