Storm Sewer Network

A system of underground pipes, ditches, channels, and structures to manage and control stormwater runoff.

A storm sewer network is a system of underground pipes, ditches, channels, and structures designed to manage and control stormwater runoff. 

It is important infrastructure that helps prevent flooding and protects the town's properties and public spaces during rainstorms and other precipitation events.

The storm sewer network consists of various components, including catch basins, culverts, ditches and manholes strategically placed throughout the town. 

These components collect rainwater from roads, parking lots, sidewalks, and other hard surfaces, moving it into the network. The system then moves the stormwater through a network of underground pipes and channels, directing it towards Lake Ontario, creeks, or stormwater management ponds

The storm sewer network plays a crucial role in preventing water accumulation on streets and in neighbourhoods, reducing the risk of property damage and maintaining public safety. 

By effectively managing stormwater runoff, the system helps to prevent erosion, soil saturation, and the potential contamination of water bodies due to pollutants carried by runoff.

Overall, the storm sewer network in the Oakville is an essential part of the municipality's infrastructure, providing effective stormwater management and protecting the community from the negative effects of heavy rainfall or severe weather events.

Keeping storm sewers functional

It the town's responsibility to ensure the proper functioning of the storm sewer network. Regular maintenance activities such as cleaning, inspection, and repair of the infrastructure are completed to prevent blockages, ensure smooth water flow, and extend the lifespan of the system.

We perform a rotational CCTV (closed circuit television) inspection program where they inspect 10 per cent of the underground network per year. Data is collected and any required works and maintenance are planned in the town’s capital forecast.

Any pipes which are identified as an emergency repair or in need of flushing/cleaning are prioritized and completed. Ditches are maintained on a complaint driven basis where Roads & Works staff will regrade ditches which are no longer flowing correctly due to erosion. 

The Halton Region maintains stormwater infrastructure under regional roads.

A few things that you can do to help our storm networks include:

  • Maintain proper lot grading
  • Keep nearby catch basins clear from trash, yard waste and construction debris
  • Proper disposal of chemicals/cleaners
  • Sump pump maintenance and inspections
  • Reducing stormwater runoff
