If you experience a septic system backup, immediately stop using all water-consuming fixtures (toilets, sinks, washing machine), avoid the affected area for hygiene reasons, and contact a qualified technician rather than attempting to open or dig into the tank yourself. Parawewa's hotline (074 060 4936) is available for urgent site assessment on existing installations.
A septic backup is unpleasant, but staying calm and following a clear sequence of steps limits both the mess and the potential health risk while help is on the way.
Immediate Steps
- Stop All Water Use: Ask everyone in the household to avoid flushing toilets, running taps, or using the washing machine or dishwasher until the issue is resolved — every extra liter adds to the backup.
- Keep Children and Pets Away: Treat the affected area as a hygiene hazard and restrict access until it has been cleaned and the underlying cause addressed.
- Do Not Attempt to Open or Dig Into the Tank Yourself: Septic chambers can pose safety risks to untrained individuals; leave inspection and access to a qualified technician.
- Call for Professional Assessment: Contact your installer or service provider promptly. For existing Parawewa installations, Parawewa can be reached on the hotline for urgent guidance.
What Usually Causes a Backup
On traditional pits, backups are most often caused by the tank reaching capacity, groundwater intrusion during heavy rain (see our monsoon impact guide), or a blockage from non-biodegradable items being flushed. A properly sized, sealed system is engineered specifically to avoid these failure points, which is why backups are rare on correctly installed Parawewa systems — but any existing installation showing symptoms should still be inspected promptly rather than left unaddressed.
