There are a few things you should consider when planning a soakaway. Firstly, the ground needs to be suitable for the soakaway. The rules for measuring the size of the ground are various, with explicit guidance provided in Part H of the England and Wales Building Regulations. The rule of thumb is that for every 50m2 of surface area for collecting rainfall, you need one cubic metre of soakaway ground. This may be hardstanding, patio, driveway, or other surface area.

Soakaways are a traditional form of surface water disposal

Soakaways are traditional forms of surface water disposal that are relatively simple to build. These structures collect runoff from roads and direct it to a place where it can be disposed of in a safe manner. These structures are generally made of gravel, and are available from most builders’ merchants. They can also be bought online and require little maintenance. To build a soakaway, you will need drainage pipes and gravel. The gravel should be sufficiently large to allow water to seep through to the bottom of the structure. When the soil starts to build up in the soakaway, you can cover it with heavy duty fabric.

The traditional method of building a soakaway is to dig a hole and fill it with debris, which limits the volume of water that can be collected. However, with the help of plastic crates, you can design a soakaway that leaves the entire area open, allowing all of the water to be collected. These crates are two or three deep, and can be assembled to serve a large area. They can handle up to 10mm of runoff within five minutes.

They are a pit in the ground

The distance between a soakaway and a house is very important when planning the installation. The location of a soakaway should be at least 5 metres from the property. It should be further away if the site is sloping. You should obtain the advice of a geotechnical expert before you install a soakaway.

A soakaway needs to be situated in suitable ground to collect the rainwater that is emitted from the building. There are rules of thumb for calculating how much of a soakaway should be installed, but more explicit guidance can be found in the Part H of the Building Regulations in England and Wales. For example, if a building has a surface area of 200m2, it should have a soakaway measuring at least one cubic metre. Likewise, a 200m2 area may have a hardstanding, a patio, or a driveway, which will need a soakaway of at least one cubic metre.

They are used to dispose of excess water caused by heavy rainfall

Soakaways should be placed at least 5 metres from the house. However, if the drive is sloping, the ACO drain should be installed against the house. Soakaways should be a minimum of 1 cubic metre in size. Different councils have different requirements.

The distance between a soakaway and a house is dictated by the number of bedrooms in a house and the porosity of the soil. New regulations state that a three bedroom house needs a drainage field the size of a five-person household. For each additional bedroom, add one person.

They can reduce flooding

Soapaways are designed to collect rainwater and percolate it back into the soil. However, they can become blocked with debris, making it impossible for rainwater to percolate back into the ground. To avoid a blockage, soakaways should be sealed off on the outside with a permeable geomembrane. The inside can be backfilled with granular material or left empty. If the soakaway is large, a cover should be fitted over it.

Soapaways are generally built up to 5m away from a house. They collect water from the roof gutters and driveways and divert them into a soakaway. The purpose of a soakaway is to store water temporarily before it reaches the home, so that it doesn’t flood or cause any other problems. However, to ensure that the soakaway is effective, it must be constructed on soft ground, so that it can absorb the maximum amount of rainwater.

They are expensive to build

There are many factors that must be considered when building a soakaway. This includes groundwater levels and ensuring that the drainage system is built deep enough. Soil conditions are also important. A specialised company will be able to assess these issues. The design life of the development should also be taken into account. For dwellings, the design life should be around 50 years, while for industrial buildings it should be at least 60 years. If you require a longer drainage system, you will need to seek permission from your local LLFA.

When building a soakaway, homeowners should consider the costs of repairing any damages caused to the system. A soakaway may have to be replaced if any of its pipes becomes damaged or blocked. While it may be cheaper to replace sections yourself, it’s advisable to hire a professional to carry out this work. Alternatively, a building insurance policy may cover the cost of repairing drainage systems.

They are difficult to maintain

A soakaway should be located at least five metres away from a building. It should also be at least two and a half metres away from a boundary. This ensures that rainwater does not run into a neighbour’s garden. It should also be free from underground services.

The size of a soakaway should be suitable for the area that it collects rainfall. There are various guidelines for measuring soakaways, with explicit guidance provided in Part H of the Building Regulations in England and Wales. As a general rule, a soakaway should be no more than one cubic metre in area. If the area to be collected is larger than this, an ACO drain should be installed against the house.
