When you’re considering a drainage system, it’s important to know what kind of system you need. Depending on where you live and what type of property you have, you’ll find different types of drainage systems. These types include subsurface drainage, surface water drainage, and combined drainage.

Surface water drainage

Surface water drainage is a complicated concept that affects both residential and commercial property owners in different ways. Across the United Kingdom, there are many different types of surface water drainage systems. It’s important to assess the entire picture when it comes to figuring out how much your property needs to pay. In some cases, a simple rebate may be enough to offset some of the costs.

Defra’s Action Plan sets out a number of key areas for improvement in the UK’s surface water drainage system. This includes the need to improve the knowledge of existing sewer systems, improve the capacity of sewers, and implement green drainage systems. However, the Action Plan does not specify what actions MHCLG should take in the future.

Subsurface drainage

Subsurface drainage is a system for draining excess water away from the surface. There are three main types of subsurface drainage, each of which has its own benefits. Osma channel drains are used to collect and transport excess water, and they are available in a variety of sizes. They are typically installed at 0.6 to 1.5 m below ground and are spaced eight to 30 metres apart. They are laid with slotted PVC pipes, and are then covered with a permeable backfill. The pipes are usually installed by a drainage trencher, which is fitted with laser guidance equipment. Once the slotted pipe is laid, the permeable backfill is delivered to the site by trucks fitted with conveyor belts. The conveyor belt feeds the backfill into hoppers. The amount of backfill is dependent on the forward speed of the truck, and the size

Sustainable drainage systems aim to replicate natural drainage patterns and reduce surface water flooding and pollution. These systems aim to balance challenges and opportunities in urban planning, as well as manage water quality and biodiversity. In addition, they can facilitate new developments in areas where there are currently full sewerage systems.

Combined drainage

When building a house, you might be wondering whether the drainage system in your home is a combined or separate one. The combined system refers to a system where the foul and surface water are carried away by one pipe. In contrast, the separate system has separate pipes for the two types of water. The main difference between the two is how the water is treated once it reaches the sewer.

Before the combined drainage system was used, sewers were designed for the purpose of carrying away wastewater from individual properties. The Victorians were concerned about the spread of disease in the sanitary system, so they built sewers to capture and transport wastewater from homes. However, they did not take into account the environmental consequences of this type of system. The combined drainage system in the UK was designed to handle the waste water produced by household appliances, grease and fat, as well as rainfall.

Fixture drains

Fixture drains are piped connections that are attached to building drains or sewers. Fixture drains are often made of fiberglass. They are designed to retain a minimum seal of 25mm of water. In the UK, Class III installations must have static trap water seals of 50mm or 75mm.

SuDS

The current SuDS drainage system in the UK has major disadvantages. One of these is the lack of consistency, quality and delivery. This impedes a more widespread implementation of this system. Another is the lack of resources allocated to SuDS development. A lack of funding and expertise within local planning authorities is one of the biggest obstacles.

To overcome these issues, the UK government implemented legislation, known as Schedule 3, that made SuDS mandatory on new developments. The legislation would have created new bodies to approve and disapprove SuDS applications. These bodies would have the power to approve or disapprove a development, and they would have to ensure that the system is constructed to national standards.
