Perforated Drain Pipe; Installation Process, Benefits, and Applications

Table of Contents

Perforated pipes are proof of modern, smart drainage systems. As indicated by their name, these pipes have many small holes through which the water can enter and exit easily. These pipes are mainly installed in underground drainage systems to prevent flooding.

Perforated pipes are designed to collect or emit water through tiny holes that vary in size. Once collected, the excess groundwater is collected for draining to a suitable site.

Salient Features of Perforated Pipes

  • Perforated pipes can be made of clay, cement, iron, and PVC. Mostly, PVC pipes are used because they are more lightweight, flexible, and cost-effective.
  • These pipes are buried underground to collect water from drain-flooded yards, fields, and wet basements. There, they collect water and drain it out. Thus, the main function of these pipes is to collect and convey water.
  • The pipe’s size and number of perforations are variable based on design. Likewise, the perforation in the pipes can be designed facing down or up, depending on their application.
  • Upward-facing perforations prevent silt and debris from accumulating in the pipe during the water collection, while downward-facing perforations are assistive in faster water collection and distribution.

Installation Process

The installation of perforated pipes demands careful planning so that the purpose of their installation is fulfilled duly. These pipes are always installed on slopes for optimal drainage. Below are the steps involved in their installation.

Trench Digging

The first step for installing perforated pipe is trench digging. The diameter of the trench is double the width of the drainage pipe, and the trench is dug deep enough to adjust the pipe below the frost line.

For larger installations, you need to carry out more extensive digging.

Creating the Slope

In the next step, a slope is created at the optimum gradient to ensure speedy drainage of the water.

Levelling the Soil

The soil in the drainage trench is levelled so that there is a firm base for the pipe to rely on and drain out speedily.

Cover with Gravel

Garvel filling is another very important step that prevents the soil from sinking. It also stops the pipe clogging and maintains the trench’s overall structure. It is mandatory to fill the gravel to 2 inches to fix the pipe affirmed in its place.

Lay the Pipe

In the final step, the pipe is laid on the top gravel. One must be careful the pipe remains levelled while laying.

Completion of the Installation

After laying the pipe, start filling the trench to cover the pipe and keep the remaining soil back to the gravel so that the pipe remains safe.

Pros & Cons of Perforated Pipes

Perforated pipes are advantageous in many aspects


  • Lightweight and resistant to moisture, rotting, and chemicals.
  • Exceptional dimensional stability, high tensile strength, and tear strength.
  • More permeable to water and air, ensuring easy flow of drainage water.
  • Low pore site to limit root fibre penetration.


  • It increases construction costs.
  • It needs routine maintenance; thereby, maintenance costs are there.
  • It has some clogging chances.


Perforated pipes are advantageous in many aspects:

Efficient Water Removal from House

In case of heavy rainfall, your lawn usually gets flooded heavily. However, a perforated pipe can help you easily avoid this problem. The pipe collects all the water and drains it out, leaving your area dry.

Water Delivery for Swimming Pools

Perforated pipes are very useful in filling in large swimming pools. Water is passed through these pipes and drained into the pool. With the help of minute perforations, you can ensure that the water goes smoothly without any debris in it.

Perforated Pipes and Landscapes

A well-designed landscape adds beauty to your home; however, keeping it tidy is of utmost importance as well. Rain or any seepage from the sanitary pipes can make it floody. These perforated pipes effectively absorb excessive rainwater and drain it away from your property.

Effective Irrigation

Perforated pipes efficiently take the water to drain it to your plants’ roots while ensuring the clean water reaches where it’s required.

Perforated Drain Pipe Installation Process


For efficient and debris-free water drainage, perforated pipes greatly support your drainage system.

However, this pipe needs an expert installation to deliver its purposes in the best way. Its installation demands careful and planned digging, maintaining optimum gradient, and levelling of the pipe. The process becomes more complicated if the diameter of the perforated pipe is large.
