When it comes to underground drainage systems, there’s no one-size-fits-all solution. Different projects require different types of pipes, and each type comes in a variety of sizes to meet specific needs. Whether you're dealing with residential gardens, industrial sites, or public infrastructure, understanding the right pipe for the job is crucial. In this guide, we’ll walk you through the different types of underground drainage pipes and highlight the various diameters available.
One of the most common types is land drainage pipe coils, which are flexible plastic pipes used to manage excess water in gardens, sports fields, and other landscaped areas. These coils come in both perforated and unperforated versions, allowing water to be collected and redirected to a soakaway system, storm drain, or natural water source. Land drainage pipe coils are available in five diameter sizes: 60mm, 80mm, 100mm, 160mm, and 200mm.
Another essential type is sewer drain pipes, typically made from PVC due to its durability and lightweight nature. These pipes feature a smooth interior surface that facilitates efficient water flow while preventing root intrusion. Common diameters include 110mm and 160mm, suitable for most household and commercial sewer systems. For heavier-duty applications, larger sizes like 200mm or even 300mm may be necessary. Additionally, perforated sewer pipes are available for applications such as land drainage around buildings or for managing surface and sub-surface water.
Twinwall surface water pipes represent another robust option, designed for high-pressure environments. Made from HDPE (high-density polyethylene), these pipes consist of two layers fused together—one smooth and one corrugated—for added strength and durability. They come in diameters ranging from 100mm to 900mm and are ideal for large-scale projects like culverts, roadways, and airport runways. Like land drainage pipes, twinwall pipes are available in perforated and unperforated versions, making them versatile for both stormwater and surface water management.
While not strictly drainage pipes, MDPE (medium-density polyethylene) water supply pipes deserve mention due to their widespread use. Known for their strength and flexibility, MDPE pipes are used for transporting potable and non-potable water. With diameters ranging from 20mm to 63mm and a maximum working pressure of 10 bar, they’re perfect for cold water systems. MDPE pipes are manufactured in blue or black to comply with UK regulations and are joined using compression fittings.
For historical charm and unparalleled durability, cast iron underground drain pipes remain a popular choice. Available in diameters from 100mm to 400mm, these pipes are ideal for rainwater and soil/waste systems. Their longevity and ease of maintenance make them a reliable option for long-term projects.
Lastly, clay drainage pipes, though less common today, are still frequently installed in the UK. Made from recycled aggregates, these pipes offer excellent structural integrity and come in standard sizes of 100mm, 150mm, 225mm, and 300mm.
