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 that manage and control stormwater runoff. 

The storm sewer network also includes components like catch basins, culverts, ditches and manholes. 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 an important role in preventing water accumulation on streets and in neighbourhoods, reducing the risk of flood-related property damage and maintaining public safety. It also helps prevent erosion, soil saturation, and the contamination of water bodies due to pollutants carried by runoff.

Keeping storm sewers functional

It is the town's responsibility to ensure the storm sewer network is working properly. Regular maintenance such as cleaning, inspection, and repair of storm network infrastructure helps 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 identified for emergency repair or in need of clean 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. 

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
