Why you need to design a below ground drainage system
You need to design a ground drainage system because there are so many parts to take into consideration.
The key components when designing a drainage system are generally:
- Gullies – these are typically designed to channel surface water from your garden, rainwater from your gutters and grey waste water from your dishwasher/washing machine, into the appropriate drains.
- Inspection chambers – these provide access to your underground pipework for maintenance and removing any blockages. Also, every inspection chamber will require a manhole cover.
- Rodding eyes – also known as rodding points, these are used to allow access into your drains for inspection and cleansing as necessary. They are almost always used in surface water drainage systems.
Because of the regulations involved in installation of an underground drainage system, it’s best to design and plan your below ground drainage systems in advance.
Almost all building projects in the UK will have a drainage layout that has been designed by an architect.
Which is where we fit in.

Below ground drainage systems installation
Below ground drainage systems will be laid in a trench, 300mm wider than the pipe itself, and lined with shingle.
When designing an installation system, we recommend following the basic drainage systems design principle that all pipes have to have easy access for inspection and cleaning.
Installation has to be laid to the correct fall – we advise 110mm drainage is laid to a fall of 1 in 40.
If you require more clarification, please refer to Document H of the Building Regulations (Drainage and Waste Disposal) for further information. If in you are in any doubt you should always seek advice from your local authority.
