If the storm water is not connected to either the foul or a separate storm water drainage system it will lead to a local storm soakaway.
Soakaways can be made in lots of different ways from the storm water downpipe just stopping when it goes underground to a correctly installed storm system where the soakaway is over 5 metres from your property as per current building regulations and the soakaway is made up of either large clean stone or storm water soakaway crates. The soakaway pipe is usually perforated at the soakaway so that water can soak away into the ground when it rains.
When your storm water pipe is leaking and the wall to your house is wet it is a sure sign you have a problem. The first step is to call out your local drainage engineer to put a high pressure water jetter down the storm water pipe.
When guttering is leaking this is an indicator that the storm water downpipes and below ground pipework is blocked. The cause of the backing up water in a storm soakaway could be a blockage of debris, silt and stone before the soakaway or the holes in the pipe could be silted up stopping the water from leaving the pipe and soaking away. There is also a chance your soakaway has run out of its useful lifetime. This is when the silt has filled all the void space around the pipe and the water really has nowhere to go when the pipe fills up.
Jetting of the soakaway will solve the problem or at least buy you more time around 50% of the time. The other 50% of the time jetting will only prove that your soakaway needs diverting or replacing.
We can give you the best advice regarding the most sensible place to divert to or we can give you a quote to install a new future proofed soakaway designed according to best practice and to building regulations.

Septic Tank Soakaways
If your property is not connected to a foul mains drain it is most likely connected to a septic tank, a sewage treatment plant, or a cess pit.
If you have a blockage the first port of call would be to check the level of your septic tank or sewage treatment plant. If the level of water is above the inlet pipe then it will follow that the water will be above the outlet pipe and there is most likely an issue with your soakaway.
If this is the situation it would be wise to have your tank emptied and at the same time call your local drainage engineers to put a high pressure water jet down the soakaway. This will clear any blockages that may be causing the back up before the outgoing pipe gets to the soakaway or it can clean the holes in the pipe in the soakaway itself.
Not the best job in the world - overflowing septic tanks indicate a problem with the soakway
Foul soakaways should be designed differently from storm water soakaways and should consist of an underground pipe with slits cut into it and surrounded by 40mm clean stone. It is the void space in between the stone which is the most important factor in the foul soakaway.
If too much sludge has entered the outgoing pipe and thus the soakaway it can fill all the void space around the pipe and this is when the soakaway becomes irreparable. This can happen if there is no dip pipe connected to the outgoing pipe in the tank for example.
If the foul soakaway has reached the end of its useful lifetime we can quote to design and install a new soakaway.
