Soakaways have different depths and the depth needed is determined by the invert level of the incoming drainage pipe. You should calculate the volume of your soakaway chamber by measuring the distance from the dry base level to the invert level. This will give you an approximate amount of depth you need to install a soakaway. Remember that you will need a deeper chamber if you plan to fill it with gravel.

BS 6297: 2007 requirements for a soakaway

A soakaway is a system that is designed to remove excess water from a garden or other area of a building. These systems are designed to meet the requirements set out in British Standard BS 6297: 2007. The regulations also require that these systems must be properly installed and approved by a Building Control Inspector. If your soakaway does not meet the requirements, you may face a fine.

If you have a suitable piece of land, you can choose a soakaway system. It is essential that the system meets BS 6297:2007 and BS EN 12566:2007 standards. The system should be designed for the level of water use and capacity and be regularly emptied and maintained.

In order to determine whether the soakaway is designed to handle the amount of water in a given area, a percolation test is required. The test involves digging a test hole at a depth of at least one metre. This measurement is important because soil porosity can vary across a site. Therefore, the tests should be conducted at the location where the soakaway will be installed. You should also avoid testing in extreme weather conditions, as this can influence the results.

Cost of a soakaway

Soapaways are a practical and environmentally friendly way to improve the drainage of a building. In the UK, the most popular soakaway type is plastic crates, as they are easy to install and have a low carbon footprint. Five manufacturers produce plastic crates in the UK, and some of them are overseas. When specifying soakaways, they should be considered in the context of the detailed design. For example, if you’re looking for a soakaway to be installed on a highway, you’ll need to think about whether it will be installed at the base of the structure.

You can also choose a soakaway for a specific area, such as a driveway. In some cases, a soakaway for a driveway is required by building regulations. However, it is not necessary if the drainage system is designed for a single surface. For a multi-surface soakaway, you’ll need reinforced crates and more piping.

Percolation tests in a soakaway

A soakaway is an underground swales designed to absorb water. These swales are installed in the soil to provide a drainage system and should be installed in soil with a low permeability. A soakaway may be a suitable choice for some soil types, but it is not appropriate for others. If you are unsure of its suitability for a specific site, it is recommended to contact a geotechnical expert who can advise you on the correct design.

When building a soakaway, it is important to carry out proper percolation tests to determine how well it will perform. Many builders build soakaways without carrying out this vital step and end up with a boggy garden and dirty surface water flooding their homes. For this reason, you must always ensure your soakaway is located at least 10 metres from a watercourse.

A percolation test is the process of measuring how well a soil absorbs water. These tests are conducted before installing a soakaway or replacing an old one. The results of these tests are used to choose the correct surface area and size for your soakaway. Below Ground Solutions has extensive experience carrying out percolation tests.

Water table depth in a soakaway

The water table depth is the uppermost layer of groundwater and can rise and fall with the seasons. If the water table is too high, a soakaway will not drain and will end up as a hole or sump. If the water table is too low, the soakaway will not drain at all and will remain saturated.

To measure the water table depth, the first thing to do is to dig a trial pit. This means digging a hole that is 300mm square and measuring how long it takes the water to percolate out of it. You can use a simple trial pit, or you can also consult a geotechnologist for advice.

Water table depth is important for the design of a soakaway. To ensure that it is effective, the water table must be at least one metre below the ground surface. It should also slope down 100mm for every four meters of pipework.
