How deep should a soakaway be?
A soakaway is a seemingly simple, yet incredibly efficient, method of disposing of excess wastewater or rainwater from a property. It is an environment-friendly process that stops wastewater from pooling close to your property, and is often used in conjunction with a septic tank – particularly in rural areas where there is no access to the main sewage system.
What Does a Soakaway Do?
Wastewater runs into the soakaway, and can then slowly diffuse into the surrounding ground as it is filtered through the rocks. Importantly, the soakway aims to slow the diffusion process in order to stop any pooling of water or flooding.
At OMDI, we have decades of experience designing and installing soakaways. Our experts know the up-to-date regulations that need to be adhered to, and can recommend how deep a soakaway system needs to be in order to be at its most efficient.
How Deep Should a Soakaway Be?
Before we install a soakaway on your property, our technicians will always run a number of tests and surveys. The primary one is a percolation test, which determines if your garden is physically suited for a soakway.
The percolation test allows us to calculate how much water can be drained off into the ground. From there, we can then calculate how deep the soakaway needs to be in order to efficiently drain wastewater that runs off your property.
The depth of a soakaway depends on a number of factors, including how many people live in your house, the number of bedrooms and size of the property, and the porosity of the ground. They are used to determine the size of the drainage area that’s required, and hence the depth of the soakaway.
The important thing to know is that the depth of each soakway can, therefore, be different, and there’s no minimum or maximum depth. Generally, for every cubic metre of drainage area, you need to dig at least one metre down into the ground. Most soakaways, for an average-sized property with a family of five, will need a drainage area of at least one cubic metre to be effective. Throughout the whole process, our team will always ensure that we follow the local Building Regulations set out by the government because they determine important factors in the design process, such as how far a soakway needs to be from a building or a watercourse.
