What is the process for having the SDF percentage reviewed?

A property owner may request a review of the SDF percentage if they believe that it is in the wrong category, or it is in the correct category but the category does not accurately represent the use at the property.

If you believe your property is in the wrong category e.g. there has been a change of use at your property, you can submit your request along with supporting documentation confirming the use of the property via email.

If your property is correctly classified but you believe the category does not reflect the level of sewer discharge here's how to go about having your SDF percentage reviewed:

  1. Request the review in writing

    You can submit your request via email, or by writing to:

    Manager Billing Operations
    PO Box 5171
    HRMC NSW 2310

  2. Consider installing sub-meters

    Install sub-meters (at property owner's expense) to isolate and measure wastewater discharged to the sewerage system from the quantity used in production and/or externally.
  3. Verify sub-meter installation with us

    We will need to verify this to ensure internal and external usage is accurate. Measured data will then be captured over a 12-month period to account for seasonal variations in usage.

Should the outcome identify the SDF to be in a different category, the SDF percentage will be set at the midpoint of the appropriate band.
