Four Types of Drainage Systems

Drainage systems are important to disperse and coral water, whether that is to collect it or ensure it doesn’t present a danger or health risks. There are four main types of drainage systems, as we are about to find out.

Surface Drainage

Channels or ditches are used to get rid of excess water. The ground may be graded or shaped to create slopes leading the water towards the channels or ditches. This kind of drainage system includes humps and hollows, grassed waterways, levees and open drains. Channel drainage is often used at domestic properties, serviced by companies such as www.wilkinson-env.co.uk/drainage-services-cctv-surveys-midlands/cctv-drain-surveys/northampton/, to remove water from large surface areas such as patios and driveways to help prevent flooding. A CCTV drain survey Northampton or elsewhere can help to ensure that this type of drain works as it should and is connected in the right way to prevent problems from occurring or reoccurring.

Subsurface Drainage

These systems are positioned below the top soil and are sometimes known as French drains. They are located in dug ditches and remove excess water by working at root level.

Slope Drainage

A CCTV drain survey in Northampton or elsewhere may be used to investigate a slope drainage system. This is built to let water flow down from a structure using pipes on a slope. Installed pipes are anchored to a slope to guide water safely and swiftly from a structure.

Gutter Systems and Downspouts

These offer an initial defence against storm water and over-saturation issues and need to be kept clean to prevent problems from occurring. They typically drain into rain barrels, buried drain pipes or aluminium extensions and move water away from structures and towards other drainage solutions nearby. In some instances, they connect to underground sewer lines using underground or gutter drains.

Working Together

Often drainage systems will work together in order to provide effective water removal and ensure that it reaches the most appropriate place. This should ensure that fast water removal is achieved to prevent damage to structures and pooling.
