Subdrain

Single wall corrugated HDPE pipe is ideal for drainage projects where flexibility, lightweight and low cost are important.

Solid, Perforated and Perf Socked in stock. Plus every fitting you need to get the job done.

Single wall corrugated pipe has kept farms, golf courses, parks and playing fields dry for decades by channeling away excess underground moisture.

Homeowners find that the single wall HDPE corrugated pipe is an economical, easy–to–install solution to common residential stormwater drainage problems. These may include downspouts runoff, foundation and window well drains, driveway culverts and wet spots on the lawn. Single wall HDPE pipe is also used for highway edge drains, culverts and other construction applications where economy and durability are a priority.

Subsurface drainage through Subdrain/ Weeping Tile installation and management works by removing excess water from fields. Improved field drainage creates significant benefits for your soil health, environmental impact, and increased crop yield for larger profits year after year.

1. Reduces Excess Water
Subsurface drainage redirects water away from areas with a high water table. This is critical for areas with frequent flooding and soil saturation that can negatively impact crop health.

2. Increases Drought Tolerance
In areas where drought is a challenge, subdrain systems can be used to improve water retention in the soil, or divert excess rainwater to holding ponds for future use.

3. Minimizes Erosion
Soil erosion and degradation can be caused by excess rainfall, resulting in loss of soil volume. This can be magnified by traditional plowing methods. Improved drainage can reduce the impact of heavy rainfalls, helping to preserve soil nutrients and the surrounding areas of your property that can be affected by erosion.

4. Lowers Environmental Impact
Agricultural runoff can be high in dissolved minerals and organic compounds, which can cause issues for neighbouring water supply. A drainage system will ensure that this runoff is redirected to avoid local rivers and ponds, protecting the local ecosystem.

1. Removes Excess Water
Effective subsurface drainage removes excess soil water in the root zone, allowing for improved soil aeration. Prolonged exposure to saturated conditions and poor soil aeration can stress the crop, reducing yield.

2. Increased Workability
Drainage can improve field trafficability, allowing more reliable field access while reducing compaction. Drier soils are less susceptible to compaction than wetter soils.

3. Deeper Roots
Drainage enables crops to establish deeper root systems in fields, allowing greater access to nutrients and soil water.

4. Improved Consistency
Drainage can reduce the year-to-year variability in yields from poorly drained fields. Drainage can increase nitrification (the conversion of ammonia to nitrate) in most soils, providing more nitrate for plant uptake.

Farmers have told us that they expect a 10 – 20% increase in crop yield after investing in proper drainage.

What it is
Drainage tile is a system of perforated pipes that redirect groundwater away from buildings and other vulnerable areas. It's also known as weeping tile, big-o, or subdrain.
How it works
Drainage tile is typically made of crush-resistant plastic and is installed underground. The pipes are laid in a trench and backfilled with the existing soil, or additional stone.
Benefits
Drainage tile helps prevent flooding and water damage, and can protect the structural integrity of buildings.
Installation
Drainage tile can be installed during construction of a new home, or in an existing home. However, installation is a major construction project that should be handled by professionals. We do have an installation guide for French Drains available to help DIYers.
Maintenance
Regular maintenance is important to ensure the system remains efficient. This includes inspecting for clogs, leaks, or damages.
Groundwater
If you live in an area with high levels of groundwater, you may need additional pumps or other equipment to assist with the flow of your drainage system.

There are two main types of tile drainage systems: surface and subsurface:
Surface drainage
Uses ditches and natural channels to move water away from the surface. Surface drainage tiles are usually placed about 6 inches below the soil's surface, and are easier to install than subsurface drainage tiles. However, they require more frequent maintenance because leaves and debris can clog the pipes.
Subsurface drainage
Uses pipes buried underground to remove excess water from the soil. Subsurface drainage tiles are usually placed 3 to 4 feet below the soil's surface, and require heavier equipment for installation. They are less vulnerable to blockage than surface drainage tiles, and provide a longer-lasting solution.

Several government programs and financial incentives exist to help farmers invest in land improvement and subdrain (tile drainage) systems. These programs prioritize environmental sustainability, soil health, and increased productivity. In Ontario, dedicated loan programs are available, while federal programs offer cost-share opportunities. All programs listed below are linked to their information and application pages to help you find the best options for your farm.

Ontario Subdrain and Land Improvement Programs

• Tile Loan Program (Ontario): This program provides low-interest loans to agricultural property owners to install tile drainage systems, covering up to 75% of the total cost.
  • Terms: 10-year term, with repayments made annually through property tax installments.
  • Maximum: The maximum loan is generally $50,000 per farmer per year, subject to municipal approval.
• Regional Tile Drainage Program (NOHFC): Specifically for Northern Ontario, this program covers 50% of tile drainage contractor costs up to $500 per acre, with a maximum investment of up to $1 million.
• Resilient Agricultural Landscape Program (RALP): As part of the Sustainable Canadian Agricultural Partnership (Sustainable CAP), this program provides funding to farmers to improve on-farm productivity and increase resilience through better soil management.

Canadian Federal/Joint Programs

• Sustainable Canadian Agricultural Partnership (Sustainable CAP): The main 2023–2028 framework providing 50–70% cost-share for various on-farm improvements.
• On-Farm Climate Action Fund (OFCAF): Provides funding for producers to adopt Beneficial Management Practices (BMPs), including those that enhance soil health and improve water management.
• AgriInvest: A self-managed account with matching government contributions that can be used for small income declines or to make investments to improve land and manage risk.
• Canadian Agricultural Loans Act (CALA): A loan guarantee program that makes it easier for producers to access credit for purchasing land or installing drainage systems.
