Looking After Your Septic Tank
Nature makes a septic tank work thanks to naturally occurring bacteria which thrive on the impurities in waste water and looking after your septic tank can help prevent pollution.
If you dispose of certain substances and materials down the toilet, or down sinks, you risk either blocking a drain or upsetting the natural balance within the septic tank. This will stop it working properly and could lead to serious problems of pollution or choking of the soakaway disposal system.
The most common problem usually encountered by a septic tank owner/user is the result of a blockage. Try to find out where the problem is and check for blockages:
- At the house - are sinks draining properly?
- At the drain trap - are there foul odours?
- At the manhole - is sewage backing up?
- At the septic tank inlet or outlet?
- At the soakaway or outlet - is effluent causing pollution?
You may be able to clear a blockage using drain rods fitted with a plunger, or you may need to call a qualified plumber
or drain clearing specialist. Your tank may also require de-sludging.
