The water that enters stormdrains in your neighbourdood is called stormwater. Any water that enters the storm drains flows directly from Lethbridge streets into the Oldman River or into storage retention facilities called storm ponds. There is no direct treatment of stormwater. Storm ponds help filter water before they reach the Oldman River.
The City of Lethbridge operates more than 30 Storm Ponds located throughout the City. These storm water reservoirs' primary function is to collect and store excess storm water to prevent flooding. Storm ponds are designed with inlets for storm water to enter during high rainfall events and outlets to slowly release excess water afterwards. Some ponds have irrigation make up water to keep them filled, because water from the pond is used to irrigate the park during the summer months. These “lakes” found in your neighbourhood are not constructed to be a public recreational facility.
You can be of service to our storm ponds by ensuring you do not release goldfish or other aquarium species into our storm ponds.

How can I get a sewer line replacement?
- Call the City of Lethbridge to obtain a video inspection to determine if replacement is necessary. A clean out must be accessible for this to occur.
Please see the sewer problems page for more information.
- Call Contractor(s) for sewer relining/replacement on the property owner's side and obtain quote(s). It is recommended that you obtain at least 2 quotes from different contractors
- Replacement occurs after verification of repairs to be done. The City will be responsible for the replacement and cost from the property line to the street. The Contractor hired by the homeowner will be responsible for the replacement from the home to the property line, with the cost to the homeowner. By doing these at the same time, it offers cost-saving to the homeowner.

Sump pumps remove water that is collected from a building’s foundation and are commonly found in basements in Lethbridge. A sump pump can sometimes create issues adjacent to the property. The property owner is responsible to address any issue identified by the City of Lethbridge.
Homes built in new neighbourhoods, since 2005, are connected underground to the stormwater system. This arrangement eliminates issues with adjacent properties.
What Bylaws cover sump pump discharge?
