Disconnecting your downspout
To disconnect a downspout, they are cut above the drainpipe and the drainpipe is capped. An elbow and extension are added to the connection to divert rainwater from flowing into your home’s private sewer drain. A splash pad can be added at the end of the downspout to help direct the flow and protect landscaping.
Benefits of downspout disconnection
Some of the benefits of downspout disconnection include:
- It reduces the amount of stormwater sent through the sewer system, which can lead to overflow into rivers, streams and lakes.
- It replenishes and protects the groundwater table and reduces and delays stormwater runoff, preventing flash flooding in rivers and streams.
- You can save rainwater in a rain barrel for irrigating your plants and gardens instead of using tap water.
- It places fewer burdens on the sewer system, leading to lower energy costs and increased effectiveness of wastewater treatment facilities.
Best practices for disconnecting your downspout
When disconnecting your downspout, water should flow onto your grass or garden. It is very important to ensure that:
- Water flows away from your foundation walls
- Water does not negatively impact your neighbours’ properties
- Water does not flow directly onto a walkway or driveway
- Your eavestroughs are clean and drain properly
- The ground slopes away from the house for a minimum of one metre
- Catch basins are free of debris
