In London and Southwestern Ontario, managing stormwater is essential for every home, commercial property, and municipal space. As urban development increases, more impervious surfaces—like driveways, roofs, and sidewalks—leave less room for water to naturally absorb into the soil. This makes stormwater drainage systems critical in protecting both properties and the surrounding environment.
At BEST Plumbing and Drainage Contractors, we provide comprehensive stormwater solutions to ensure every drop is managed safely, efficiently, and in compliance with local codes.
What Is a Stormwater Drainage System?
A stormwater drainage system is designed to collect, direct, and manage rainwater runoff. Without these systems, water accumulates quickly and can cause structural damage, erosion, and even contamination of local waterways. These systems prevent pooling, basement flooding, foundation cracks, and soil displacement.
Stormwater drainage systems are made up of several interconnected components that work together to divert water away from structures and into safe discharge zones. These systems are not only functional—they also help maintain the value of your property and ensure environmental protection.
Key Components of an Effective Stormwater Drainage System
Each component of a stormwater drainage system plays a specific role in ensuring that water is captured, filtered, and moved safely. Here’s a breakdown of the most important elements:
Gutters and Downspouts
Gutters collect water from your roof and direct it to downspouts. Downspouts then guide the water away from the building’s foundation. Improperly placed or clogged gutters can lead to overflowing water, which seeps into basements or damages siding.
Catch Basins
Catch basins trap surface runoff, often near driveways, curbs, or paved areas. They filter out debris before sending water through underground piping. Regular cleaning is crucial to ensure they remain effective.
Storm Drains and Drainage Pipes
These underground components move stormwater from your catch basins and downspouts to municipal sewers or designated discharge areas. They rely on gravity and precise grading to transport water efficiently.
French Drains and Dry Wells
French drains use perforated pipes wrapped in gravel to redirect water from wet areas. Dry wells collect excess water and allow it to slowly seep into the ground, helping recharge groundwater supplies.
Retention and Detention Ponds
These are common in commercial or suburban developments. Retention ponds hold water permanently while detention ponds store water temporarily during storms and release it gradually.
Grading and Swales
Proper grading around your property ensures water flows away from structures. Swales—shallow, grassy ditches—help direct runoff naturally and reduce flow speed, preventing erosion.
Why Proper Stormwater Management Matters
Prevent Flooding and Water Damage
Without proper drainage, stormwater builds up around your property, causing flooding. Water can seep into your basement, weaken foundations, and ruin landscaping. In extreme cases, it may even lead to mould growth and structural collapse.
Protect Property and Infrastructure
Stormwater can erode soil, crack concrete, and cause pavements to heave or sink. These issues are costly to fix. A well-designed drainage system maintains the integrity of driveways, sidewalks, and home foundations.
Improve Environmental Health
Runoff from driveways and roads often carries oil, chemicals, and debris into local waterways. Drainage systems with proper filtration components, like stormceptors or bioswales, reduce pollutants before water reenters the ecosystem.

No two properties are the same. Soil type, slope, structure layout, and weather patterns vary. We assess your site in detail to design a custom stormwater drainage plan that addresses your unique challenges. Whether you need a backyard French drain or a full-scale commercial retention system, we tailor our approach.
High-Quality Materials and Installation
We use only industry-approved, durable materials that withstand Ontario’s extreme weather conditions. Our installation teams ensure every pipe, catch basin, and downspout is positioned for maximum performance.
Expert Troubleshooting and Upgrades
Already have a system that isn’t working? We diagnose and resolve drainage issues with precision. Common problems include improperly graded surfaces, undersized pipes, or clogged outlets. We provide efficient solutions, including system expansions and upgrades.
Preventative Maintenance Services
After installation, ongoing care ensures your drainage system continues to work reliably. We offer maintenance plans that include cleaning catch basins, checking for blockages, and inspecting grading.
Advantages of Professional Drainage Installation
Improved System Efficiency
DIY systems often fall short in performance. Professionally designed drainage ensures water flows freely, even during heavy storms, reducing risks of overflow or pooling.
Long-Term Cost Savings
Investing in professional services now prevents future repairs. Avoiding damage to your foundation, landscaping, and hardscapes can save thousands over time.
Increased Property Value
A functioning, code-compliant drainage system increases curb appeal and resale value. Buyers and inspectors look for properties with no water damage or flooding risks.
Peace of Mind
When storms roll in, you’ll have confidence knowing your home or business is protected by a system built to handle the weather.
Sustainable Drainage Solutions for the Future
We prioritize environmentally conscious options whenever possible. Our team integrates green infrastructure into stormwater systems, including:
- Rain Gardens: Beautify your landscape while absorbing and filtering stormwater.
- Permeable Pavers: Allow water to seep through rather than run off surfaces.
- Green Roof Systems: Help commercial properties reduce runoff and improve energy efficiency.
- Bioswales: Channel water through planted areas that naturally filter pollutants.
By integrating sustainability into your drainage system, you not only protect your property—you also protect Ontario’s waterways and wildlife.
