Subdrain/Weeping Tile

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.

Subdrain installation and manufacturing requirements are changing, and we’re excited to be a part of it. At the Land Improvement Contractors of Ontario (LICO) meeting last month, the organization voted in favour of the drainage industry adopting third party certified pipe by the end of 2024.

LICO is an association of professional contractors, suppliers of drainage pipe and equipment, engineers and municipal drainage superintendents principally concerned with agriculture and the land drainage industry of Ontario, Canada. LICO Contractors are government licensed and principally design and lay tile drains on farms and construct the necessary municipal outlet drains.

More information about LICO can be found on their website here.

What is BNQ Certification?

The Bureau de normalisation du Québec (BNQ) is accredited by the Standards Council of Canada (SCC) as a certification organization. This accreditation ensures a conformity assessment issued by an impartial third party in compliance with international requirements applicable to certification bodies. The BNQ is proud to offer certification programs that have earned it tremendous credibility internationally. As an independent third party, the BNQ insists on exemplary professional ethics that every employee and contractor must follow.

Why Does BNQ Certification Matter?

Certification is a measure of quality, ingenuity, and progress. BNQ certified products must develop and improve in accordance with industry requirements and modernization.

This certification exists to provide customers with certainty that the manufacturer is following the industry proven testing protocols. Confirming that they supply quality products using a consistent manufacturing process.

Both Bluewater Pipes and Fittings have been certified since September 2023. Only nine manufacturers Canada-wide are currently accredited, and only two in Ontario. We’re the official distributor of Bluewater Pipe for the Niagara region.

The certification requirements for drainage products can be found here.

Who Does This Decision Impact?

With LICO endorsing BNQ certification it improves the industry standard to ensure that farmers are purchasing high quality products, bringing increased integrity to the drainage market.

With the expansion of manufacturing capacity of corrugated drainage pipes in Ontario by new businesses, the adoption of a third party certification program ensures all manufacturers, new and old, will be supplying products compliant with proven performance standards. When investing in your farm it’s important to get the best product for long-term reliability and value. BNQ certification polices the quality to ensure your investment is a good one.

We’re proud to be the only official distributor of Bluewater Pipe for the Niagara region. Your BNQ certified subdrain option.

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.
