What is stormwater?
Stormwater, as defined in the Halifax Water Rules and Regulations, is:
“water from precipitation of all kinds, and includes water from the melting of snow and ice, groundwater discharge and surface water”.
All properties generate stormwater, even if it is a small amount, under certain conditions. Properties with impervious surfaces such as roofs, asphalt, concrete, bricks and packed gravel tend to generate more stormwater than properties with pervious surfaces such as natural forest, lawns and gardens.
Impervious surfaces generate more stormwater than pervious surfaces as they prevent or limit the entrance or passage of stormwater.
Halifax Water stormwater infrastructure
Halifax Water’s (the public) stormwater system is comprised of:
- roadside ditches
- stormwater holding tanks
- off street drainage corridors
- and ponds, dams, or catch basins that eventually discharge into a local brook, river, lake or the ocean.
This is infrastructure located on public property, or within Halifax Water or Halifax Regional Municipality easements. Ditches/culverts that are found at the boundary of a private property/driveway on public land are considered part of Halifax Water’s stormwater system (initial installation of culvert is paid by the customer).
Understanding stormwater flow from your property
Halifax Water stormwater infrastructure may be directly adjacent to your property, or they may be some distance away, in which case stormwater may have to flow overland, along roadways, or through watercourses (lakes, rivers, etc.) before reaching the Halifax Water stormwater system. Most of the properties within the boundary receive one or more of the following services from Halifax Water:
- stormwater from the property enters any part of Halifax Water's stormwater system
- the property is accessed directly by a driveway that crosses over a Halifax Water culvert
