What is a Catch Basin?

A catch basin, also called a storm drain, collects and directs water, melting snow, and debris away from properties to prevent flooding. It connects to plumbing that channels excess water to a sewage system, reservoir, or sump. Catch basins are commonly found in both residential and commercial areas, where they manage stormwater and protect properties from water damage.

Do I Need a Catch Basin?

If your property experiences drainage issues, like a soggy lawn or wet basement after rainfall, a catch basin can help. These basins collect water runoff and connect to the municipal stormwater system, offering effective drainage for homes and businesses. A drainage contractor can install, maintain, clean, and repair your catch basin.

A consistently wet yard may not be a problem if it creates a natural marshy area. In some cases, this space can benefit local wildlife and increase habitat value, if allowed by regulations.

However, if you live near neighbors or in a city, drainage issues are common. Standing water or concerns about a wet basement often signal the need for a stormwater catch basin.

In addition to a catch basin, adding a sump pump and investing in exterior waterproofing for your home or structure can prevent future problems. Mould spores that form in damp environments are a genuine health concern, as they can be harmful when inhaled.

 Catch Basins Manage Urban Drainage Challenges

The close proximity of properties often leads to drainage issues in low-lying areas, especially with impermeable surfaces like blacktop and concrete replacing greenspace. Efficient city design relies on shared services and compact footprints, saving municipalities money. In London, Ontario, located in a topographical basin, the risk of water accumulation and drainage problems is higher. With limited green space on most properties, excess water becomes a concern, varying by property specifics. Ideally, expansive greenspace would allow rainwater and spring thaws to gradually absorb into the soil. However, since most properties lack this, engineered solutions are necessary to prevent flooding, protecting both your property and your downhill neighbor’s.

How do Catch Basins Work?

Catch basins gather rainwater runoff from hard surfaces such as residential patios, streets and sidewalks through a grate, which filters out larger debris like leaves and twigs. The collected water flows through a pipe to a storm drain or drainage system, helping to prevent flooding and decrease pollution in nearby waterways. By trapping sediments and contaminants, the catch basin acts as a short-term storage for stormwater, allowing solids to settle before the water is released into natural bodies of water.

Catch Basin Types

Catch basins vary in size and design, with options like open and closed systems, and are constructed from a range of materials. The ideal type for a specific area is determined by factors such as the volume and nature of the water it will handle.

Stormwater catch basins can be customized for your property’s needs. You can select from different basin sizes, and depending on your property’s layout and flood risk, you might even need two catch basins. Household catch basins are typically a one-foot box with a heavy-duty grate and filter. Larger catch basins are necessary for commercial and industrial facilities, where parking lots need bigger basins with concrete receptacles. These basins require regular cleaning, often done by a BEST Drainage JetVac Services.

The Pros and Cons of Catch Basins

Pros of Catch Basins:

• Flood Prevention: Catch basins effectively manage stormwater runoff, helping to prevent flooding in residential basements, commercial properties, and nearby areas.
• Property Protection: They divert water away from structures, safeguarding foundations, basements, and landscaping from potential damage.
• Enhanced Drainage: Catch basins direct rainwater to proper drainage systems, reducing the risk of pooling and standing water on surfaces.
• Environmental Impact: They filter out debris and pollutants from stormwater, improving water quality before it reaches nearby waterways.
• Aesthetic Integration: Catch basins can be seamlessly incorporated into landscaping designs, preserving the visual appeal of outdoor spaces.
• Cost-Effective Solution: Installation and maintenance costs remain low, requiring only regular cleaning for optimal function.
• Increased Property Value: Addressing drainage issues with a catch basin boosts property value, making it more attractive to potential buyers.

Cons of Catch Basins:

• Clogging: Leaves, dirt, and sediment can block the basin, reducing its drainage capacity and leading to flooding during heavy rainfall.
• Maintenance Requirements: Catch basins must be cleaned, either by you or through affordable Jet/Vac services, to remove accumulated debris.
• Pest Infestation: Stagnant water in catch basins can create ideal breeding grounds for mosquitoes and other pests.
• Wildlife Risks: Small animals, including frogs and turtles, may become trapped and drown in catch basins.
• Environmental Impact: If poorly designed, catch basins can trap pollutants from runoff, potentially contaminating nearby water sources.
• Installation Expenses: Installing a catch basin, particularly if excavation is required, can be costly.
