A simple guide to Underground Drainage

So, now the weather’s getting warmer and the days are getting longer, you’re probably thinking about updating your underground drainage, right? Whether you’re a beginner or simply looking to refresh your memory, let Total Pipeline Systems guide you through the process of installation.

Contact the Building Control Department

First and foremost, make the Building Control Department your point of contact. They will ensure that your proposed plans are practical and possible and take into account legal regulations to ensure your project doesn’t break any laws.

Your local Building Control Department is always on hand to help, so if you have any queries or uncertainty, be sure to contact them and they will be more than happy to guide and advise you.

Know your drain types

There are two types of underground drainage systems:

1) Foul water drainage – comprising sewage and grey waste from toilets, sinks, bathrooms and kitchen appliances
2) Surface water drainage – made up of rainwater only

Please note, older properties tend to have surface and foul water running into the same pipe and this is perfectly fine, however, there needs to be a trapped gully to prevent foul water escaping. Newer properties, on the other hand, have separate systems which is considered to be best practice.

Choose equipment wisely

When selecting drainage pipes and fittings, only choose brown pipes as these are specifically designed for underground drainage.

You will need:

• Plain end drain pipes
• Drain couplers
• Standard bends
• Rest bends
• Pipe lubricant
• Gullies
• Small inspection chambers

We supply a complete range of 110mm underground drainage pipes and fittings, here at Total Pipes, so you needn’t worry about finding exactly what you need.

Have a plan

Knowing what goes where and how it all connects together is ideal when it comes to installing underground drainage. Make sure you have a clear idea of how the equipment works and whether it obeys building regulations.

Create a diagram that you can refer to throughout your project. Getting your ideas down on paper will ensure you have every aspect covered and will guarantee no interferences with the foundations of your property.

Be prepared

Don’t rush into underground drainage. Take your time when digging trenches and make sure that you pay careful attention to building regulations. Drainage pipes must be installed 300m below ground level and pea shingle should be placed at the base of the trench to form a bed, providing stability.

Although UPVC underground drain pipes and fittings are prone to wear and tear, you need to regularly maintain them to ensure they last longer.

You also need to make sure manholes, chambers and gullies are easily accessible in case of emergencies, blockages and repairs.
