Septic systems and components library

Identifying an off-mains drainage system

Septic tanks, sealed cesspools and package treatment plants work in different ways. The guides in this library cover the main system types and components, routine maintenance and faults that may need separate investigation.

• System identification: manufacturer, model and system type.
• Use and maintenance: properties served, occupancy and last emptying or service date.
• Observed problem: slow drainage, alarm, odour, backing-up or wet ground.
• Discharge arrangement: where effluent goes and which UK nation the property is in.
