A Guide to the Various Underground Drainage Pipes & Fittings

Underground service and water lines are built using a variety of pipes, including metal and synthetic pipes. Before establishing an underground water supply line, it is best to check local codes or a building specialist, as climate and site factors can affect a pipe’s performance.

In this post, let’s look at the numerous drainage pipes and fittings used in underground piping systems, their applications, and the various piping materials employed.

What Is an Underground Drainage System?

An underground drainage system is a network of pipes that are intended to transport wastewater away from any residential, commercial, or industrial site. By doing so, water contamination and infections caused by wastewater can be avoided.

Wastewater is disposed of utilising specialised plastic pipes built to function effectively underground, such as SS141 and SS213 uPVC pipes. In residential and commercial areas, wastewater or rainwater can be directly conveyed to an open water body via a drainage system. However, for industrial uses, wastewater is first treated to remove dangerous compounds before being discharged into a free-flowing body of water. Different drainage pipes and SWR pipes are used depending on the drainage type.

Buried water lines must be composed of materials resistant to deterioration and punctures as they are exposed to moisture and vulnerable to unintentional shovel hits. Longevity is crucial for pipes that are difficult to reach, like supply lines buried behind a slab of concrete.

Underground Drainage Pipes

Drainage pipes are essentially designed to dispose of excess water from one place to another. However, different types of drainage pipes are installed to cater to different purposes. Let’s have a look at the types of drainage pipes.

Copper Pipes

Plumbers frequently use copper to join underground water supply lines. Despite their rigidity and corrosion resistance, copper pipes can erode in specific soil types. As such, builders frequently sheathe copper supply lines in synthetic sleeves when the soil or site conditions pose a risk of corrosion.

Unlike other materials, copper is frequently permitted by universal codes for various applications. However, fluctuations in the metals market have an impact on the price of copper. Thus, copper pipes are often more expensive than plastics like PVC and CPVC.

Concrete Pipes

Another common option for drainage and sewer operations is concrete pipelines, commonly found in rural areas. Although these pipes are quite effective, they leak more frequently and are less durable than metal or uPVC drain pipes.

Plastic Pipes

For sewage and drainage systems that are underground, plastic pipes are, without a doubt, the finest choice. Compared to metal and concrete pipes, these are more cost-effective, easier to install, corrosion-resistant, and require less maintenance. PVC, uPVC, and polyethene are just a few of the many materials that make up plastic pipes



Vicplas’s sewage pipes and fittings selection is appropriate for residential, commercial, and industrial applications. To dispose of rainwater and excess water, the SWR (soil, wastewater, and rainwater) drainage system is implemented. Water contamination is thus avoided, putting an end to all types of water-borne ailments. These pipes are also used to collect rainwater.

Underground drainage pipes made of uPVC are employed in both domestic and commercial settings. These pipelines are used to move hazardous wastewater from industries to a water treatment facility and for regular sewage operations. After the inebriated water has undergone water treatment, the pipes transmit the fluid into an open water body.

Which One Should You Buy?

Plastic pipes have established themselves as a superior alternative to metal and concrete pipes for sewage systems, whether for residential, commercial, or industrial uses. In conclusion, SWR drainage pipes and fittings are ideal for managing surplus wastewater and collecting rainwater.

The transfer of industrial and the disposal of residential wastewater are best handled by uPVC underground drainage pipes. These pipes are perfect for draining excess water to preserve the appearance and feel of your landscape as they are underground.
