Are you setting up a new business in a property you are leasing?

  • The owner of the property is responsible for water usage and sewerage charges.
  • Depending on the terms of your lease agreement  the property owner might decide to pass along the charges to you the property renter.
  • Are you creating liquid waste?

Waste water from food preparation, washing dishes and cleaning that goes back into the sewer may need to be treated before it can be discharged. You’ll need a trade waste agreement and potentially a grease trap.

Visit our trade waste pages to find out more about setting up a trade waste agreement.

  • Are you changing the interior of the property?

    You might need to submit a plumbing application with us to make sure the changes to the internal plumbing comply with the water services to the property.
