How Rain Can Affect Your Drainage System?

Drainage System Lifting Out The Ground

Now, before your imagination runs away with you, don’t expect to see your septic tank levitating round the garden, but, heavy rainfall can cause your drainage system to rise up slightly out of the ground by a few inches or feet depending on the severity of the problem. As such, the pipe connecting the septic tank or sewage system to your home splits, causing your household waste to spill into the septic tank’s hole or straight into the ground: not nice!

Boggy Ground

Boggy ground is a common sign that there’s a deeper problem with your drainage system. It can be hard to tell if boggy ground is simply a result of heavy rainfall or a drainage issue, therefore, we’d advise waiting until drier weather to see if the ground is still covered with boggy patches or if the problem dissipates when the rain stops.

If in doubt, don’t hesitate to contact our engineers who can assess whether there’s a problem with your septic tank.

Problems In The Home

Excessive rainfall doesn’t just cause problems with your septic tank outside. Another sign of septic tank damage from rainfall can be slow flushing toilets or gurgling drains. These can be a sign of a full or blocked septic tank and should be investigated by an expert straight away before the problem worsens.

What Should I Do If I Suspect A Drainage Problem?

If you suspect that excessive rain has damaged your septic tank, soakaway or sewage treatment system in any way then it’s vital that you contact an expert. Issues, however small, need to be investigated and resolved straight away to prevent further damage and expense.
