How to Fit the Perfect Underground Drainage System

A good underground drainage system can prevent the build-up of surface water and help to avoid erosion - either of the surrounding landscape or any nearby buildings.

Draining an area of land can also increase the variety of uses for which it is suited, and can prevent the growth of moss and lichen.

So how do you put together the best possible underground drainage system? Of course, the exact components you’ll need will depend on the size and layout of the area you wish to cover.

However, the specialists at Total Pipes can give you some great tips for planning and installing your new system. Read on for their expert advice.

Check sizes and distances

First of all, you need to decide on the area that will be covered by your drainage system. Work out where the problem areas are and research the fittings that would best solve each particular issue.

This will inform you of the specialist components and lengths of pipe you will require. Make sure that all pipes and sockets are designed to fit together.

Plan carefully

Draw a map of your planned drainage system, marking the precise location of each part. This will come in handy if repairs are required further down the line.

You should think about how you’ll be able to clear blockages in the future - be sure to install roddable fittings or inspection chambers.

You should also check that you have the full complement of tools and materials required. We recommend:

  • Sturdy gloves
  • A spade (you may require a mini-digger for larger jobs)
  • A shovel
  • Pea shingle
  • All pipes and drainage components
  • A tape measure and marker pen
  • A saw
  • A file or rasp to chamfer pipe ends
  • Lubricant

Check standards, safety elements and regulations

Before you begin the installation, take time to examine the relevant building regulations, including the correct depth for underground pipes and the permitted height for access or inspection chambers.

Work out the location of service cables and pipes - such as those importing gas and water - to avoid damaging them. You should also take care not to dig too near walls, as this may cause them to subside.

Once you have created your trench, lay out all elements of the drainage system and make sure they are well-aligned. This will help to maintain a full flow and prevent blockages.

Get fitting

We recommend lining the bottom of each trench with pea shingle, as this will allow you to shift each part of the system around until it is all level. The whole network should be well-supported, especially components such as rest bends.

Once you are confident in your plan and layout, you can get started. Measure, mark and cut each length of pipe as you go to make sure everything fits well.

Apply lubricant to the seal of each socket for easy insertion and to prevent damage. Make sure that each length of pipe is pushed as far as possible into its socket, as this will prevent leaks.

Depending on the design of your components, you may feel a click when each part is fully inserted.

Follow the advice above, and you’ll be able to create an excellent drainage system. For help or advice, simply contact Total Pipes today.
