MY TANK IS OVER FLOWING, WHAT IS WRONG?
A septic tank if working correctly should not
at anytime over flow. The level should remain constant at the base of
the outlet pipe (see The
Operation of a Septic Tank) and as shown below in the drawing
of a simple septic tank unit.
If
your tank is over flowing you need to check if you have been
de-sludging on an annual basis. If you have then it is likely that
there is some problem with the system.
1/.
If you are lucky there may be a blockage or build up of debris on the
outlet T pipe, a simple de-sludge should solve the problem.
2/.
If the soakaway is no longer effective (see
How does a Soakaway Work) and may have come to the end of its
useful life, then a new soakaway will need to be installed.
3/.
The septic tank may be undersized for the current usage. If the tank
was built in the 1930,s then it was not designed for that dishwasher
and en-suite shower! A new septic tank or sewage treatment plant may
need to be considered.
