Frequently Asked Questions

What is commissioning, and why do I need it for my sewage treatment plant?

Commissioning is a crucial process where your sewage treatment plant is thoroughly inspected, tested, and fine-tuned to ensure it operates efficiently and meets all regulatory requirements. It helps identify and resolve any potential issues, ensuring the system works optimally from the start, and it’s often required by local authorities to obtain permits for operation.

Who will do the commissioning?

The commissioning process will be carried out by a GRAFter, who has experience and training in commissioning and servicing our sewage treatment plants.

How long does the commissioning process take?

The duration of the commissioning process can vary depending on the complexity and size of your sewage treatment plant. In general, it may take 45-60 minutes to complete all the necessary checks, tests, and adjustments to ensure everything is working optimally.

Is commissioning required for all types of sewage treatment plants?

Yes, commissioning is essential for all sewage treatment plants, regardless of their size or technology. It ensures that the system is functioning correctly, meets environmental standards, and operates efficiently to treat wastewater effectively.

What can I expect during the commissioning process?

During the commissioning process, our team will conduct a comprehensive assessment of the sewage treatment plant’s components, test its functions, and calibrate the settings to achieve the desired performance. We will also train you on the operation and maintenance of the system to ensure you can manage it effectively.

Is there any cost involved for the commissioning service?

As part of our commitment to providing exceptional service, we offer the commissioning service at no additional cost when you purchase a sewage treatment plant from us. It’s our way of ensuring that your system is set up correctly and operates efficiently, giving you peace of mind. Please refer to our T&Cs for further information.

How often should I schedule maintenance after commissioning?

Regular maintenance is vital to keep your sewage treatment plant operating smoothly. After commissioning, we recommend following a maintenance schedule provided by our team. Typically, periodic inspections and servicing once a year are sufficient to maintain optimal performance. Please refer to our T&Cs for further information.

What if there are issues after the commissioning process?

In the rare event that you encounter any issues after commissioning, don’t worry. We provide post-commissioning support and warranty to address any unexpected problems that may arise. Our team will promptly attend to the issue and make sure your sewage treatment plant operates flawlessly.
