The underground drainage system is a network of pipes that take water away from your property. The pipes are terracotta in colour and are laid in a trench. They are equipped with access fittings, inspection chambers and manholes. A plumber can put a cable down the drain or locate the pipes and cables.
It is a network of pipes taking water away from your home
There are two main types of drainage pipes in the UK: private drains and sewers. Depending on where you live, sewers are the responsibility of the local water sewerage company. Private drains are the responsibility of the home owner, landlord or letting agent. If you find your drain blocked, you may need to call a professional drain clearing service to fix the problem. If it is not an emergency, you can use a pressure hose to clean the drain.
The main purpose of underground drain pipes is to carry water away from your home. The water is taken away in two different ways: surface water drainage (which deals with rainfall around your property) and foul water drainage (which deals with water from your toilets and sinks). Most homes have separate drains for surface water and wastewater. In some areas, the wrong connection between the two types of pipes can lead to a problem causing water pollution. Generally, a surface water drain takes rainwater directly to the river or beach while a foul water drain takes wastewater to a local wastewater treatment plant.
Your home drainage network connects to the main sewer pipe that services other homes. The rules for this system were set in 2011 by the Private Drains and Sewers Act. Sections of the piping within your property boundary are the responsibility of the homeowner, while pipes outside your property boundaries fall under the responsibility of the water company.
It is laid in a trench
Underground drain pipes are laid in a trench. To lay them, a trench must be dug and filled with granular material suitable for the type of soil in the trench. A common material used is pea shingle. In addition, the building regulations require appropriate backfill or bedding materials. These materials are graded according to the soil type and the overall weight load that is expected of the drainage system.
Drainage systems have a long history. They first appeared in Mesopotamia about 9000 years ago. Early drains were probably just trenches partially filled with permeable materials, such as bundles of small trees or shrubs tied together. The oldest drainpipes were found in the Lower Indus river valley around 2000 BC. Ancient Chinese also used bamboo sticks drilled with holes to install drainage systems.
Underground drainage systems should include a number of access points, inspection chambers, manholes, and other features. The drainage trench must be dug properly to avoid blockage and provide sufficient flow. The trench should also be properly supported at all sides. A pipe laser level is useful for this task, as it has a screen that displays the fall in the trench.
It is terracotta in colour
The colour of underground drain pipes and fittings is an easy way to identify them. The industry standard is terracotta and most pipes are this colour. These fittings and pipes are manufactured using the same machinery and are almost identical in colour. Some of these fittings are also available in other colours, such as black, white or grey. Some pipes are UV-treated for extra protection.
This underground drainage pipe is 110mm in diameter and 6 metres long, and features a unique lip seal to make joining and dismantling easy. This pipe is made from PVCu and is lightweight. When installed, it is best to use a lubricant for the joints. The fittings are also the market leader and feature a captive seal.
When installing a drainpipe, you must ensure that it is the right size and type for your home. Most drains require 1.5 inches of pipe. Some older homes may have terracotta, cast iron, or Orangeburg pipes. However, many modern homes have plastic pipes. Terracotta pipes are clay-based ceramic pipes that date back to the ancient world. This type of pipe is air-dried for 24 hours before firing.
It has inspection chambers, manholes, roding eyes and access fittings
In the UK, underground drain pipes have a range of access fittings and inspection chambers. These can help assess the condition of drains and sewers and prevent people from entering without the necessary authorization. Some of these access fittings are manholes and require a confined space risk assessment before being used.
Inspection chambers are integral parts of any underground drainage system. They provide easy access to the drainage system and keep the distance between inspection cameras and the system manageable. Typically, inspection chambers are installed where a drain pipe changes direction by more than 30 degrees or when a straight run of piping is longer than 20 metres. A good rule of thumb is to install as many inspection chambers as possible throughout the drainage system.
Rodding eyes are another type of access fitting used to inspect surface water drains. These access fittings feature a short section of pipe set at 45 degrees to the main pipe. A covered oval opening is provided in the cover to allow access to inspection equipment and drain rods.
