Stormwater Management System
The purpose of a municipal stormwater system is to collect, convey and discharge stormwater runoff to the natural environment in a safe and controlled manner. A municipal stormwater system consists of service connection pipes, catchbasins, mainline sewers, manholes, culverts and stormwater management ponds.

What is Stormwater? 
Stormwater is rain, melting snow, and ice that washes off driveways, parking lots, roads, ditches, yards, fields, rooftops, drains, and other surfaces.
What is Stormwater Management?
Stormwater Management (SWM) is the installation and application of infrastructure, naturally designed systems and ongoing operational programs to mitigate the impacts of stormwater to our communities and the natural environment.

Stormwater Management Activities
- Operation and Maintenance
- Repairs (to pipes, culverts, maintenance hole and catch basin frames and lids, ditches, etc.)
- Stormwater Management (SWM) pond inspections, maintenance and clean outs
- Asset inspection and maintenance program (pipes, structures, culverts, ditches, oil grit separators, etc.)
- Infrastructure locating services
- Digital database maintenance and filing
- Regulatory compliance (monitoring and reporting)
- Stormwater Servicing Area Studies
- Asset Management review and inventory
- Infrastructure replacements and improvements

Stormwater Systems
County of Brant stormwater systems are located throughout the County with the largest systems being in Paris, St. George and Cainsville. They include:
Culverts |
A stormwater culvert is a structure that allows water to be moved under a road, entrance, or similar area. Culverts are not permitted to be installed to facilitate the installation of piping under a roadway (example irrigation piping). |
Storm Sewers |
Storm sewers are pipes that convey surface water runoff from rain and melting snow and discharges it to stormwater management ponds or natural bodies of water (ie. river). |
Stormwater Service Connection |
A stormwater service connection connects a private property to the municipal stormwater system. Stormwater Service connections for individual residential properties are only allowed under special circumstances and must be approved by the County. |
Stormwater Management Ponds |
A stormwater pond collects and stores excess storm water to prevent flooding. These ponds are not constructed for public use. Do not allow children or pets near stormwater ponds. Stormwater ponds are designed with inlets for stormwater to enter during high rainfall events and outlets to slowly release excess water afterwards.
Stormwater pond maintenanceThe County of Brant maintains 23 stormwater management ponds located in Burford, Oakland, Paris, Scotland and St George.
The County's role in pond maintenance includes:

The County of Brant regulates the discharge of materials to municipal and private storm sewer systems. This is to protect water quality by preventing the discharge of harmful substances to municipal and private storm systems and ultimately to water bodies within the County.
Discharges that do not meet the requirements outlined in the Storm Sewer Use ByLaw (PDF) may have serious consequences for public health and safety, municipal infrastructure and the environment.
