Installing a plastic drainage pipe is a labour-intensive job that requires careful planning and execution. Before beginning, it is crucial to call ahead and have your utility lines marked to avoid property damage and fines. The route of the drainage pipe should be carefully planned, ensuring it travels from a high point to a low point with a steady downward slope to prevent water pooling. The trench for the pipe should be 8 to 10 inches wide and 18 inches deep, with a firm and smooth bottom. The type of pipe used, whether open or closed, will depend on the specific drainage requirements. Open pipes are typically used to divert water from a general area and have holes along their length, while closed pipes are used for more targeted water diversion.

What You'll Learn
Planning your drainage pipe route
Firstly, determine the purpose of your drainage pipe. Are you diverting water away from a specific area, or collecting water from a general area? This will impact whether you need a closed or open pipe system. A closed system is used to divert water from one specific point to another, while an open system is used to collect water from a general area and will have holes along the length of the pipe.
Once you've decided on the type of system, plan the route of your drainage pipe. The route should be as direct as possible, travelling from a high point to a low point with a steady downward slope to prevent pooling at low spots. Mark out the route, ensuring it is clear of any utility lines to avoid damage and unnecessary fines.
When you have your route planned, start digging the trench. The trench should be eight to ten inches wide and about 18 inches deep, with a smooth and firm bottom. Remember to save the sod by cutting it out with a machete and setting it aside, so you can easily replace it later. Ensure your trench follows the downward slope in the direction you want the water to flow.
If you are installing an underground drainage system, there are specific guidelines to follow. The trench should be dug out with the correct "fall" to use gravity to move wastewater effectively. Then, lay the trench with pea shingle to protect the pipework. There should also be a minimum of 300mm cover on top of any buried pipework.
By following these steps, you will effectively plan your drainage pipe route, ensuring a smooth installation process for your plastic drain pipe.

Digging the trench
Digging a trench for your plastic drain pipe is a labour-intensive job, so be prepared for some hard work! Before you start, call ahead and get your utility lines marked—this will help you avoid any unnecessary damage to your property.
The trench should be dug along the route you have already decided upon for your drain pipe. It needs to be eight to ten inches wide and about 18 inches deep, with a downward slope in the direction you want the water to flow. The bottom of the trench should be firm and smooth. You can save the sod by cutting it out with a machete and removing it in sections with a square shovel. Keep the sod and set it aside, so you can replace it once you've laid the pipes.
When digging the trench, it's important to make sure it has the correct "fall" to use gravity to move the wastewater. The trench should then be laid with pea shingle to protect the pipework. There should be a minimum of 300mm cover on top of any buried pipework.
Remember, the most important aspect of any underground drainage system is that it must travel from a high point to a low point with a steady slope to prevent pooling at low spots. The route of the pipe should be as direct as possible.

Laying the pipes
Next, dig a trench along the chosen route. The trench should be eight to ten inches wide and about 18 inches deep, with a downward slope in the direction you want the water to flow. The bottom of the trench should be firm and smooth. Before laying the pipes, wrap them in a filter fabric to prevent large pieces of debris from blocking the pipe. If using clayware pipes, take extra care to avoid accidental breakages during handling. For plastic pipes, simply use a hacksaw to cut them to size, whereas clayware pipes will need to be cut with special pipecutters or a power saw.
If your system is a closed drainage pipe, you can join as many lengths as necessary with the fittings provided. If you are running water away from a general area, you will need open pipes, which usually come in short sections with a row of holes down their length. For socketed clayware pipes, lay them with the 'female' end pointing upstream. For plain-ended pipes, which have identical ends, join them with a coupling. Once all the pipes are laid, confirm that there is a steady downgrade for the entire length of the system before filling in the trench.

Wrapping the filter fabric
When installing a plastic drain pipe, wrapping the filter fabric is an essential step to ensure the long-term functionality of your drainage system. Here is a detailed guide on how to wrap the filter fabric effectively:
Prepare the Trench: Before wrapping the filter fabric, you must first prepare the trench. Start by digging a trench that is deep and wide enough to accommodate the drainage pipe and a layer of gravel or rock. Ensure that the bottom of the trench is firm and smooth, and sloping downward to guide water away from the affected area. This slope is crucial to prevent pooling and promote proper drainage.
Choose the Right Filter Fabric: Selecting the appropriate filter fabric is vital. The two primary types of geotextile landscape fabric are non-woven fabric and woven fabric. Non-woven fabric, also known as landscape drainage or filter fabric, is specifically engineered to allow water to pass through while filtering out dirt and debris. It is highly permeable and effective in preventing clogs. Woven fabric, on the other hand, offers excellent tensile strength and is typically used for soil stabilization and erosion control. Consider the specific needs of your drainage system and choose a fabric with the right permeability and strength.
Wrap the Pipe: Now, it's time to wrap the drainage pipe with your chosen filter fabric. Secure the fabric tightly around the pipe using ties or tape. Ensure that the pipe is completely covered, creating a protective barrier. The fabric will prevent soil, sediment, and other particles from clogging the pipe while allowing water to flow through freely. Take your time with this step to ensure a thorough and secure wrap.
Place the Wrapped Pipe in the Trench: Once the pipe is wrapped, carefully place it in the trench. Position the pipe at the bottom of the trench, ensuring that the holes are facing downward. The downward orientation of the holes is crucial for effective drainage. After placing the pipe, cover it with a layer of gravel or rock. This layer provides additional protection and facilitates proper drainage.
Add an Extra Layer of Filter Fabric: For enhanced protection, consider adding an extra layer of filter fabric. After placing the pipe and gravel or rock in the trench, cover the entire setup with the remaining filter fabric. This extra layer acts as added insurance against soil intrusion and can significantly improve the longevity of your drainage system.
By carefully following these steps and paying attention to the details, you can effectively wrap the filter fabric when installing a plastic drain pipe. Remember that proper installation is critical to ensuring the functionality and longevity of your drainage system.

Finishing the trench
Once you've installed your pipe structure and covered it with gravel or crushed stone, you can begin finishing the trench.
First, remove the tape that was used to protect the channel opening during installation. Then, place the drain cover over the channel opening to complete the trench drain system. If you're using a concrete base, you'll need to let it cure and set before commissioning.
If you're installing a French drain, fill the trench with topsoil and compact it to completely cover the entire system. When filling the area around the inlet grate, temporarily cover the grate to prevent any stones or soil from falling in. You may need to reseed the surface or cover it with landscaping stone.
To prevent erosion where the drain pipe ends, create an area of large rocks that will absorb and disperse the energy of the water as it exits the pipe. Use rocks of different sizes and shapes, and arrange them in a way that's aesthetically pleasing. This allows the water to soak naturally back into the ground.
