Service of a Tricel Sewage Treatment Tank


Tricel Vitae >97.5% BOD treatment plant

Domestic household customer requiring servicing on a Tricel Vitae UK6 97.5% sewage treatment tank

When a customer phoned Depawater Ltd recently with a septic tank maintenance enquiry for a Tricel Vitae 97.5% sewage treatment tank, we initially assisted them by informing them to call NI Water to empty the sludge compartment in the unit. Emptying the sludge compartment annually is a critically important part of maintaining your septic tank or sewage treatment tank. Currently, in Northern Ireland, this de-sludging service is provided annually by NI Water.

You must call NI Water (0345 7440088) or book online to avail of this service as the maintenance of your septic tank or domestic wastewater treatment system is the homeowner’s responsibility as set out in your consent to discharge approval.

Once the Tricel Vitae wastewater treatment system had been desludged, Depawater scheduled an appointment with the customer for the next day, to carry out a full health check on all the components of their domestic sewage treatment system and ensure proper operation and function.


Depawater Ltd. providing great service, just when you need it!

The customer wanted to ensure that their treatment tank had been thoroughly maintained in order to comply with their consent to discharge approval.  We were able to give them this peace of mind whilst also eliminating the risk of system breakdown which can lead to foul odours, pollution and blocked drains.

Our professionally trained and British Water accredited service engineers were able to easily explain the workings of the system, helping the customer to clearly understand the importance of routine treatment tank service and maintenance.  By following a step by step process, all components of the wastewater treatment tank were checked and cleaned, filters were replaced and any blockages cleared, ensuring correct flows and continuous high performance from the Tricel Vitae 97.5% sewage treatment tank.

A comprehensive service report is always filed and a copy is given to the customer, informing them of the actions carried out and the condition of all parts of their system. This information is logged/updated into Depawater Ltd.’s unique service database containing the complete service history which may be accessed anytime.

When a new customer is added to our servicing database, Depawater will provide a free courtesy call every year, to remind them to empty their septic tank or sewage treatment tank and to help them keep on track with the necessary service and maintenance requirements.
