On-site sewage treatment systems – odours from tank
Repair
- call a specialist septic tank cleaning service to pump the tank out
Cause
System is suffering from ‘shock loading’: a sudden, large volume of effluent entering the treatment system. Insufficient bacteria are initially present to accommodate the loading following a period of non-use (typically occurs in holidays homes or where there is intermittent use of the system)
Repair
- wait until the bacteria count rises to a level where it can accommodate the loading
