septic tank problem

Looking for answers please.

Septic tank last emptied in August, but we are having issues with flushing, so John has rodded the drain and lifting the lid on the ST he has found it to be full of water.

He is down town trying to hire a pump to pump the water out into the filed. He then plans to climb inside the tank to see if he can see anything to explain what is happening. Shocked

The only thing I can think of is a blocked outlet to the runoff. How serious is this to remedy?
Any other ideas as to possible reasons ?

Is the ground around dry, or damp? If its sodden there my be nowhere for the soakaway to go.

Too late to find out!

He's a-pumping!

Please be very careful and wary about getting in the tank, confined spaces, gas build up etc.

Can you define full?


They are supposed to stay full to the bottom of the outlet pipe.

Apparently the big tank seems okay. The little tank (the one that gets the water and allows it out to the soakaway is the one causing the problem (although how the big tank filled so fast I dont know).

John says the little tank was silted up at the bottom, where the 3 exits are placed. He has now cleaned all this, but im concerned that the problem is outside the tank, where the water exits the exits (if you follow me).

I have that problem temporarily if the field next door to me is flooded....less of a problem now even if it is as there is mostly only me putting anything into the system!

If you don't get your septic tank emptied regular the sludge will go through to the out let and block your soak away and then you'll get it backing up all the time

This may indeed be the problem....
we are working on it.

If a septic tank is installed correctly,you should`nt need to empty regulary,the one here has`nt been emptied for 25yrs.

But saying that,a septic tank with soak away,is not the best choice ,if you do not have free draining soil texture,where the soak away outlet is situated,
If you have clay,you are better off with a cesspool,which does need emptying regulary.

I've had to renew a few soak aways for different people because of this.

Those seem to be problems with new type systems,

The old type septic tank,brick /block built,with a 2nd chamber filled with graded stone to filter,with out let at base,piped to a further hole dug,and filled with graded stone,tofilter further ,before dispersing to the ground.

I remember those sort of tanks, they weren't exactly water tight. These new ones are water tight, even the concrete ones, its mainly the fibre glass tanks i put in for people because they're cheaper

Dont know if this is 'old' or 'new' - it was put in in 1977.

The civil engineering friends have been round and the general gist is that its the outflow that's blocked. They are now drinking cider mulling over the problem.................

not going to get done in the near future then.......... Laughing

Or it may be cleared using a controlled explosion and natural jetwash...

Soakaway at the end of its life.

Septic tank soakaways don't live forever. If yours is from 1977, it has done remarkably well to last so long. You can't mend them either - all the rodding and jetting in the world won't help.
See this page for a good explantaion of your problem.

Replacing soakaways makes up a good part of my business, but as your tank is so old, you would probably be better off replacing it with a sewage treatment plant, especially if you have a ditch to put the water into.

As John said they don't live forever and has done to last this long, I had a similar problem but these guys helped: http://mpcservices.co.uk/contacts

Good Luck!
