Five questions to ask about rain water leaders and stormwater management

What is a rain leader system?

‍
A rainwater leader (RWL), also known as a stormwater drain, is a pipe that channels rainwater from your downspouts and directs it into the city drainage system. Stormwater management is crucial to protecting the foundation of a building. Rainwater leaders are a crucial part of exterior drainage management, ensuring rainwater is properly channeled away from the structure. Their main purpose is to control rainwater flow from your roof and eavestrough system, preventing water damage to the building's foundation, keeping your basement dry, and protecting your landscaping.

‍Does my house have rain leaders?

‍
Look near the base of your downspouts. If you see an inlet or pipe where the downspout connects directly into the ground or your home, it's likely connected to an underground stormwater leader system. Walk around your property to see if the water is directed toward specific drainage areas, such as swales, trenches, or underground drains.

Are my rainwater leaders working?

‍
When debris like leaves, twigs, shingle grit, and sediment from your roof and eavestroughs flow through the drainpipes, they can get stuck and cause problems. A clogged drain often leads to overflowing gutters. Additionally, tree root infiltration can block the drainage system, as roots seek out moisture and can penetrate the pipes, exacerbating the issue and potentially leading to more severe drainage problems.

How do I fix my rainwater leaders?

‍
The first step is to assess the condition and cleanliness of the drains. A camera drain inspection can help identify any necessary rain leader maintenance, repairs, or cleaning requirements. If your rainwater leaders are clogged or dirty, they will need to be thoroughly cleaned to remove sediment, organic material, and root infiltration. Depending on the situation, hydro-jetting can be used to clear clogs with high-pressure water, while steaming or flushing may be employed for less severe blockages. A professional will advise on the appropriate next steps if the drains are damaged or broken.

‍How often should I clean my stormwater drains, and how do I keep them clean?

‍
Hydro-jetting a rainwater leader (RWL) system is far easier while it’s actively draining. Regular maintenance, inspection, and cleaning—recommended annually—can help prevent costly damage to your foundation, landscaping, eavestroughs, and roof.
