Advice: Septic Tanks

How often will the septic tank need emptying?

It depends on the size of the tank you have installed, and levels of use. Typically, septic tank systems are sized to allow for emptying about once a year.

It’s important to have the septic tank emptied at the correct intervals, otherwise there may be an excessive build-up of sludge and a serious risk of contaminating the soakaway system with solids, which the soakaway is not designed to handle at all. Such contamination will impair the functioning of the soakaway and, ultimately, hasten the requirement for a new one.

Unfortunately, many septic tanks are not de-sludged and their soakaways become ineffective. A professional inspection can reveal whether this has occurred, and remedial action advised.
