If your soakaway is blocked, you need to understand what can cause this. This article covers three causes of blocked soakaways: accumulated silt and debris, root ingress and damage. It also covers some methods to unblock a blocked soakaway.

Blockage caused by accumulated silt and debris

A blocked soakaway system has several common symptoms. These symptoms occur when the drainage system is clogged with sediment and silt. If the non-woven geotextile or the perforations in the soil are damaged or clogged with silt, the drainage system may not drain water as efficiently as it should. The blocked system may also result in overflowing outside drains.

The first step to remediating a blocked soakaway is to identify the source of the sediment. A simple source control technique can significantly reduce the sediment entering the soakaway system. Such source control measures should be part of the overall soakaway maintenance plan. Using the CivilWeb Soakaway Design spreadsheet can help you account for sedimentation during the design phase of a soakaway. The software includes a Factor of Safety (FS) that relates to expected sedimentation and associated reductions in design infiltration rates.

Blockage can also occur when a soakaway is damaged and leaks organic waste matter into the soil. This could be the result of a faulty installation or a poorly maintained septic tank. Another common indicator of a blocked soakaway is the presence of a foul smell and unusually boggy ground.

The solution to a blocked soakaway can be as simple as removing the crate or non-woven geotextile covering the catch-pit. Another common solution involves digging up the entire soakaway and removing the pipes or crates that are blocking the drain. This method is recommended if the pipes or crates are damaged or collapsed.

Damage caused by root ingress

If you have a soakaway, you should take steps to prevent tree roots from entering it. Tree roots can damage pipes in your drainage system, causing flooding and a blockage. In order to prevent this from happening, you should cut back the trees or shrubs growing near the soakaway. You can also dig away the roots and remove material that has accumulated up to the system. However, if the problem persists, you may need to install a new soakaway system.

Damage caused by tree roots is one of the most common causes of blocked drains in the UK. It can also cause a manhole to overflow. These problems can be costly to fix, requiring expensive pitch fibre repairs, drain relining, or even excavation. This is why most surveyors recommend a pre-purchase CCTV drain survey to spot any problems.

If you have a soakaway that connects to a public sewer, you need to prevent tree roots from entering the system. The main cause is root ingress, which occurs when roots grow into a pipe or joint. If you don’t get rid of the root problem, you will end up with a blocked soakaway, which is not only expensive but also causes other problems.

Another cause of blockages is damage to soakaway pipes. If the pipes are damaged, they may become blocked and cause flooding in the septic tank. In some cases, the problem can be resolved by cutting out the roots. Another option is to repair the pipes, which is a much less intrusive and less costly solution.

Methods of unblocking a blocked soakaway

If your soakaway system is getting clogged, there are several methods available. First, it’s important to inspect the soil to see if it’s able to filter wastewater. If it can’t, then the soakaway will get blocked. In addition, there are strict regulations regarding discharges to the ground. A properly designed soakaway will keep your site safe, clean, and environmentally friendly.

Using high-pressure water jets is a great way to fix a blocked soakaway. This process involves inserting high-pressure water jets into the pipes and backwashing the area to remove debris. If this method doesn’t work, there are two other ways to fix a blocked soakaway.

The first method involves using a bend in a wire to hook the blockage. Once the material has been hooked, you should be careful to not inhale any sewage, as this can cause a new blockage. Then, place a piece of wood over the blocked area.

Another option is to reline the drain pipes, which involves injecting polymer into the clogged area to restore smooth flow of water. The cost of these methods depends on how severe the blockage is and where it is located. Rodding is less expensive than jetting, while combining methods can increase the price.

A blocked soakaway system can lead to a clogged drain and water pooling around your property. It can also cause your drains to overflow. If you notice any of these symptoms, you should contact a specialist organisation for advice.
