The decomposition process in the tank slows down, consequently waste starts to back up rather than drain away. Eventually, you may find your washing machine runs slower or your toilet flush is weak.
As your tank is out of sight it is easy to forget about it. However, the most obvious sign that your tank needs emptying is overflow and water-logging in the area surrounding your tank – noticeable by the foul smell!
Tanks need to be emptied regularly to prevent solid waste from eventually building up where it can’t be compacted anymore. As a result, toxins and antibacterial substances build up killing the vital bacteria that break down the waste. Some tank emptying service providers will filter the extraction, because of this they only remove liquids. If this continues, subsequently over time the tank fills up with solids which can damage your septic tank system and cause costly damage.
Building Regulations 2010 – Drainage and waste disposal
