4 Types of Drainage in the UK

What are the 4 different types of drainage UK

Surface water drainage is one type of drainage. This type of drainage is made up of pipes that collect and move water from the surface to the ground. Fixture drains are another type of drainage system. Both of these types of drainage are necessary in the UK. However, a combination drainage system is not recommended, because it might cause sewage to enter the drinking water.

Surface water drainage

Surface water drainage in the UK is a complicated topic that affects both commercial and residential property owners. Different types of surface water drainage are used across the country, and homeowners can take advantage of substantial rebates for making improvements to their drainage systems. To find out if you qualify, contact your local water company and fill out an application form.

Property owners are legally obligated to prevent floods and maintain drains free of debris. They are also required to prevent water from draining into neighbouring properties. While this is in the best interests of residents, a common law requirement requires property owners to prevent flooding, and it also protects the natural right of drainage, which means that water should flow naturally to your neighbour’s land. Disregarding this right may result in civil action. Property owners have several options for surface water drainage, but choosing the right type depends on your personal circumstances.

Fixture drains

Fixture drains are often visible parts of a drainage system. They have an opening that allows for a flow of waste water, and many times are equipped with a blockage mechanism. Fixture drains may also be referred to as U-bends or P-traps. These systems trap the waste water before it can enter the sewer system, keeping it from rising.


A U-bend is one of the 4 main types of drainage in the United Kingdom. This drain type has a curved pipe and is often used for sinks. Its purpose is to stop foul gasses from rising into the property. These pipes are also known as fixture drains.

A drainage system can be surface water, foul water, or a combination of both. Different properties will have a different type of system. Generally, modern properties are fitted with DUAL systems – a system for surface water and one for foul water. But even if your property isn’t on the main sewer network, it may have a septic tank installed in the garden.


A P-trap is a section of drainage pipe that is moulded into the letter “P”. The trap acts as a seal to prevent unpleasant gasses from rising into the drain. This type of drainage is also sometimes called a bottle trap. It is the most commonly used drainage method in the UK.

P-traps are generally smaller than s-traps. Their general shape is similar to that of a sideways “P.” The main disadvantage of s-traps is that they siphon away too much waste water, leaving the drain “dry”. Leaving the drain “dry” allows sewer gases to leak into the room, which can be bad for your health.

A p-trap is also easier to siphon dry than other types of traps. Nevertheless, if the water inside the p-trap is too low, it may cause the water inside the trap to evaporate, resulting in a dry trap. You can avoid this problem by regularly checking your plumbing system. If the water inside the P-trap becomes dry, you can use a drain cleaner to increase the water flow through the pipe.


Before the development of sewerage systems, the River Thames was filled with raw sewage. It was a dirty, smelly river, filled with human waste, industrial discharge, and slaughterhouse effluent. This problem was compounded by the widespread use of flushing toilets, which clogged cesspits and sent more waste into the river. A solution to this problem was needed. Civil engineer Joseph Bazalgette, the chief engineer of the Metropolitan Board of Works, spent several years planning a revolutionary sewerage system. However, his plans were repeatedly shelved due to controversies about the system’s merits.

In the UK, sewer workers are often a source of entertainment. There’s no better way to celebrate a New Year’s Eve than to find a treasure buried deep inside a sewer. Thankfully, sewers are not as filthy as they seem. In some cases, even human waste is removed. In one case, the City of London spent PS70 million to clean up the area’s sewage system.
