Helping to avoid costly blockages
Some customers will be required to fit pre-treatment equipment such as grease interceptors, cooling pits or screens, before they discharge their trade waste.
Installing and maintaining pre-treatment equipment helps to:
- Protect the operation of the sewage treatment plant.
- Maximise the life of sewer pipes, including the plumbing inside your property.
- Prevent costly blockages and expensive downtime.
- Provide a safer working environment for you, your employees and people working in and around the sewerage network.
