01 Nov uPVC: The Best Pipe for Underground Drainage Systems
It is crucial for any property to have an underground drainage system with long-lasting, durable pipes to transport wastewater away from its premises. However, given the variety of alternatives, many individuals may be curious about the ideal pipe for underground drainage.
Proper drainage is essential for preventing water from accumulating in the foundation. Many consider uPVC pipes to be ideal for underground drainage. This is because they are lightweight, economical, and can endure up to 100 years when properly installed and operated. Continue reading to discover more about underground drainage pipes and the characteristics that make uPVC pipes the finest choice.
Drainage Pipes
Underground drainage pipes, sometimes called “sewer” pipes, are hugely suitable for all underground operations. These pipes, which range in diameter from 4” to 12”, are buried in the ground to provide subsurface drainage for fields, parks, sewers, or drainage connections. The soil acts as a filter, preventing contaminants from reaching groundwater.
Underground drainage pipes are typically made from high-density polyethene that is resistant to UV rays, which prevent discolouration and cracks in the pipe. They are flexible and easy to install, making them convenient for contractors. The pipes are also typically manufactured in a golden-brown hue and are connected using either an integrated rubber ring connection or solvent cement welding. This permits slight deflection and soil movement during installation.
Types of uPVC Drainage Pipes
Underground drainage applications favour uPVC pipes built from durable plastic. This is because it is widely accessible, inexpensive, weatherproof, and adaptable to various levels of water and configurations.
Most uPVC pipes have a 4-inch diameter and may be trimmed to size with a PVC saw. uPVC is typically preferable to concrete pipes as it offers lower installation and labour costs, thus being more cost-effective.
The pipes listed below are essential for underground drainage systems:
- HDPE/N 12 Corrugated Dual Wall Pipe – The most durable option with high-density polyethene pipe.
- Corrugated Flexible Drainage Pipe – Is used to construct a French drain and retaining wall drainage. However, it is not the toughest.
- Schedule 20 Sewer & Drain Pipe – It is light, appropriate for stormwater, and widely utilised in residential settings.
- Schedule 40 Sewer & Drain Pipe – Durable and adaptable for both indoor and outdoor drainage.
- SDR 35 Sewer Pipe – It is common in municipal systems but is also suitable for residential use, with a diameter ranging from 4 inches to 3 feet.
uPVC Drainage Pipe Maintenance and Installation
It is vital to consult with local authorities before constructing an underground drainage system to determine if any permits are required. Doing so will also help avoid damage, as any substantial utility lines on the property can be located.
It is critical to plan where the water will flow before digging. Once a strategy has been implemented, the digging process can begin. An area will be cleared for a trench to produce a slope, allowing gravity to flow wastewater forward. The depth of the trench can be calculated using the soil composition, topography, and pipe diameter used.
Drywall will then be installed to catch the water that drains through the pipes and away from the premises. The pipes will be connected after the installation of padding for the drainage pipes. They will also be protected by being wrapped with protective materials to avoid damage.
An examination of the system will be carried out to ensure that it is capable of removing water. It is crucial to keep an eye out at this stage for any flaws or necessary modifications. Once it is a success, the work area will be filled to a safe depth below surface level, covering the pipes until they are no longer exposed and visible.
Different Sizes of uPVC Drainage Pipes
Most underground drainage systems can convey wastewater using 4-inch pipes. However, a greater diameter is required for locations with high building density or areas with significant water accumulation.
Contractors often use 3, 4, or 6-inches diameter drain pipes for projects. These pipes, along with their fittings, are widely accessible at stores. They are also inexpensive and easy to set up.
Because schedule 80 or 120 drain pipes are thicker than schedule 40, they are better suited for underground installation. 163 gallons can fit inside a 4-inch pipe per meter. The capacity of a 6-inch pipe is 487 gpm. Schedule 40 pipes, despite being lighter than schedule 80 or 120, can be utilised in drainage systems, walls, ceilings, and concrete encasements.
The appropriate pipe diameter can be identified by assessing the property or land.
Conclusion
A suitable underground drainage system made of dependable material is essential. Experts recommend uPVC pipes as they are a reliable material that is light, flexible, and has a lifespan of up to a century. They are less likely to break or crack and resist corrosion from the soil, chemicals, and other materials transported through the pipes. Moreover, using uPVC drain pipes reduces the risk of flooding, which could harm the foundation of the building and the nearby landscape.
