Sewage Treatment Plants Troubleshooting

Tricel Novo

Sewage Treatment Plants Troubleshooting tips

When correctly installed, operated and maintained a Tricel Novo sewage treatment plant will give you many years of trouble-free service.

Common sewage treatment plants problems

For a full list of symptoms (such as alarm, odours, pump or blower) the possible causes and the corrective actions to take, please refer to the Sewage Treatment Plants Troubleshooting section on our manual (page 33 to 36)


All plants come fitted with an alarm. A buzzer will sound to alert a fault in the air blower or discharge pump. You can mute this until the problem gets fixed. Once fixed, the alarm will reset automatically and the mute switch must be turned off. All electrical work shall be carried out by a qualified person.

Contact us if you’re alarm is buzzing.


  • Please note: before taking any corrective action, always positively identify the real source of the smell. Check if the odour is coming from another outside source such as a storm drain.
  • All wastewater disposal plants vent gases back through soil pipes and out of roof vents. Improperly installed roof vents can cause odour problems.
  • Traps / U-bends in drains prevent odours from entering the home. To function, they must contain water and be sealed correctly.
  • It is also good practice to vent the tanks just after the discharge pipe.

For any other request don’t hesitate to contact us directly.

Sewage Treatment Plants Troubleshooting – Regular maintenance

How to maintain a Tricel Novo?

The maintenance of the Tricel Novo sewage treatment plant is a simple process. An annual inspection is recommended to validate the proper functioning of the wastewater treatment system.

Please note: Maintenance should be carried out by a suitably trained person. Sewage and sewage effluent can carry micro-organisms and gases harmful to human health. Any person carrying out maintenance on the plant must be appropriately trained. Suitable protection equipment including gloves, goggles, etc., should be worn at all times. Always remove contaminated clothing and protective equipment after completion of work. Wash hands and face prior to eating, drinking or smoking.

A certain amount of plant maintenance is required, on an ongoing basis, to ensure that the plant is working correctly. This maintenance is the responsibility of the homeowner.

The homeowner can do regular maintenance

The vent around the base of the blower housing guarantees a fresh supply of air to the air blower. The vent under the de-sludging cover allows gas to escape and stops the tank from becoming pressurised. All vents should be checked to make sure they are not blocked or obscured. Ensure the air blower is working by listening for a gentle hum when standing beside the plant. Inspect pipework for blockages if necessary.

A qualified person should do yearly maintenance

The Tricel Novo plant will require a full service every year to guarantee that the efficiency of the plant is maintained.

During routine servicing, the following items get checked if applicable:

  • Sludge return
  • The functionality of blower and/or pump
  • Pump pressures
  • Pump filters get replaced
  • Pump diaphragm checked
  • Alarm checked
  • Ventilation function tested
  • Diffuser monitored to check for dispersion of air
  • Tricel covers and locks
  • Manifold adjusted

Book your yearly service/maintenance.

De-sludging of Tricel Novo

The de-sludging of the Tricel Novo plant is the responsibility of the homeowner. It is required when the sludge is occupying 50% of the volume of the primary chamber. For health and safety reasons, we strongly recommend the de-sludging is carried out via the use of a licensed company.

A constant supply of electricity

An electrical connection to the wastewater treatment plant must get maintained for it to function correctly. This connection ensures that the plant has a continuous air supply, and where necessary the discharge pump will operate. Should the plant be used intermittently, or if extended periods of non-use are expected, it is recommended that the plant remains on and in operation.

Wastewater treatment plant troubleshooting: precautions to take

To ensure the continuation of the plant’s performance, we recommend taking the following precautions:

  • High volume discharges such as those from swimming pools and Jacuzzi’s must never enter the plant. Surface water must not enter the plant.
  • Do not allow large quantities of chemicals to enter the plant including:
  • Water softener regenerate
  • Disinfectants
  • Strong Acids and Alkalis, or Photographic Chemicals
  • Oil or Grease
  • Petrol or diesel
  • Pesticides
  • Large quantities of milk, alcohol or food
  • Large amounts of bleaches or cleaners
  • Baby wipes, cosmetic and cleaning wipes
  • Sanitary towels/Tampons
  • Kitchen paper
  • Nappies
  • Medication
