A surface drain is the water that drains from a property and into the sewer system. It can be found in a variety of places including yards and rooftops. Learn about the different types of surface water drains in the UK. Also, learn more about culverts.
Water that drains away from a property
In the UK, there are many different types of surface water drainage. This is where water collects from roofs, guttering, and yards before being drained to a sewer system. If you live in an area with a lot of surface water, then it is crucial to ensure that this water is drained away properly.
The easiest way to check whether your property is connected to a sewer system is by looking at the guttering and any sunken areas. Also, if there are rainwater downpipes on your property, this is a sign that you’re in a soakaway system.
Sources of surface water drainage
Surface water drainage is the process of collecting and processing rainwater that falls on a property. Most of this water goes into public sewers. There are ten water and sewerage companies responsible for this process. Depending on the area you live in, you may be entitled to a rebate for this service. You can check your local company’s website for more information.
The UK is facing the problem of rising flood waters, and people living in flood-prone areas are in desperate need of help. Flash floods are causing excessive damage and destroying communities, so finding a way to manage this is essential. The first step to solving this problem is to understand where the surface water drainage system is located on a property. For instance, if you live in a newly built development, you should check your Title Deeds to ensure it’s connected to the local drainage system.
Methods of removing surface water from a property
Draining surface water from a property can be an essential part of preventing flooding. There are two major types of drainage on a property: soakaway and public sewer. While the majority of properties drain directly into the sewer, many homes also have soakaways to catch surface water and prevent flooding. Soakaways are usually made from stones and gravel and are located about five to eight metres away from a property. They work by allowing surface water to slowly soak away and filter back into the soil.
Sewerage companies charge for the surface water they collect. The amount collected annually is around PS1 billion. Those who build their own soakaways could get an exemption from this charge.
Culverts
A surface drain is a drain on your property that collects rainwater. Most of it drains into a public sewer, however, some surface water drains into a private wastewater treatment plant or a cesspit. This is done to prevent flooding. In the UK, there are several types of surface water drains, including those in yards and roofs.
French drains are a popular type of surface drain. They consist of a linear excavation backed by granular material such as shingle. Some French drains are more advanced and lined with a permeable geotextile membrane. They are commonly found alongside motorways.
Roadside ditches
A roadside ditch is often a dangerous place for vehicles to crash into. Not only can they cause damage to vehicles, but they can also become stuck and cause serious injuries. The word ditch originated from the Anglo-Saxon word dic (pronounced “deek” in northern England and “deetch” in southern England). Initially, ditches were made by digging a trench and upcast soil was used to form a bank. Later, ditches were shortened to “dike”.
The responsibility for ditch maintenance rests with the landowners who are adjacent to the highway. Landowners are legally obligated to maintain ditches, which are a natural drainage system for both the land and the highway. The highways authority also has the right to drain stormwater from the highway to ditches adjacent to their property.
Ancient stormwater runoff systems
For almost 2,000 years, people have been using stormwater runoff systems to move water from low-lying areas to the city center. A recent study has revealed a series of underground canals that convey runoff from Pompeii to the Bay of Naples. These ancient tunnels have now been excavated and are being brought back into use. The reconstructed system has confirmed that ancient civilizations had stormwater management systems, and the findings are not unique to these ancient civilizations.
