Business pricing, fees and charges

In June 2020, IPART finalised its review of the prices that Hunter Water’s can charge for the period ending in June 2024. Customers will benefit from lower bills over this period and increased investment in the region’s water and wastewater infrastructure.. Below are the prices effective from 1 July 2024.

For a complete list of current prices, see our Customer Charges Guide or see the relevant charges that apply to your business' water and sewer services.

Water charges

Decorative

Business customers using our water services, can incur fixed a water service charge, a water usage charge and a zone-based charge.

  • Fixed water service charge

    A fixed water service charge for operating the water system which is calculated based on the size of each billable water meter connected to the property.

    Water service charge per meter size

    Annual service charge
    20mm$27.58
    25mm$43.10
    32mm$70.62

    40mm

    $110.33
    50mm$172.40

    150mm$1,551.38
    200mm$2,758.00
    250mm$4,309.38
    300mm$6,205.50
    350mm$8,446.38
  • Water usage charge

    A water usage charge is applied to the volume of water used by an individual customer. Usage charges are calculated by a tier one charge (where <50,000 kilolitres total consumption is used during the year) followed by a zone based charge (for any consumption over 50,000 kilolitres during the year).

    During periods of drought, the water usage charge will increase to reward people for saving water when it matters most and to reflect the extra costs associated with drought related activities. The drought response water usage charge will start 31 days after water storage levels fall below 60% (the “on” trigger) and will remain in place until 31 days after water storage levels rise above 70% (the “the off” trigger)

    We publish current storage levels on our website and will communicate if the drought response water usage charge is to be introduced. View current water storage levels.

  • Zone based charges - Standard water usage

    For zone based charges the usage price varies according to where each property is located within our area of operations and is greater than 50,000kl consumption in a year.

    Water usageUsage charge (per kL of water used)
    0-50,000kl$2.89

    1 kilolitre (kL) - 1000 litres

Sewer charges

Decorative

Business customers using our sewer services, can incur a fixed service charge, a sewer usage charge (calculated using a sewer discharge factor) and environmental improvement charge.

  • Fixed sewer service charge

    Fixed sewer service charges fund most of the cost of operating the sewer system, and are calculated using the following equation:

    (Meter connection charge by meter size x Sewer Discharge Factor %)

    The Sewer Discharge Factor (SDF) represents the estimation of the proportion of water used that is discharged to sewer. A minimum sewer service charge applies to non-residential connections which is equivalent to the residential base sewer service charge of $696.78 per annum.

    Meter sizeMeter connection charges (per annum)
    20mm$929.04
    25mm$1,451.63
    32mm$2,378.35
    40mm$3,716.17
    50mm$5,806.52
    65mm$9,812.99
    80mm$14,864.68
    100mm$23,226.07
    150mm$52,258.50
    200mm$92,904.00
    250mm$145,162.50
    300mm$209,034.00
    350mm$284,518.50


  • Sewer usage charge

    Sewer usage charge$0.77per kL (1000 litres) used

    A sewer usage charge is applied to the volume of water used by an individual customer.

  • Sewer discharge factor

    What is the Sewerage Discharge Factor percentage?

    The Sewer Discharge Factor (SDF) percentage calculates fixed service and sewer usage charges for non-residential properties.

    How is the SDF percentage determined?

    For non-residential properties, the SDF has been broad banded into five bands. A property will fall within one of the bands based on use, which then determines the likely amount of water being discharged to the sewerage system as wastewater.

    Each SDF band has an allocation midpoint. This helps keep usage charges consistent for all customers who fall within the defined band. SDF's banding methodology categorises non-residential customers and allows for varying sewer discharge volumes, even within similar business types.

    A small number of large industrial customers may be required to have a dedicated meter installed to measure all wastewater discharge to the sewerage system.

    Table 1 SDF categories and band midpoints

  • Trade waste fees

    To be conscious of our environment, it's important to us that additional trade wastewater is properly disposed of. Learn more about the charges involved in its disposal in our trade waste guide.

  • Miscellaneous services

    On top of our general services, we offer a mix of miscellaneous services so that we can meet the needs of all of our customers. See what additional options are available to you and their accompanying fees as stipulated by IPART.

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 Retail Services
    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.

Frequently asked questions

  • What is the new drought price?

    The Independent Pricing and Regulatory Tribunal (IPART) has introduced a drought price for the first time. This means that if water storages drop below 60 per cent total capacity, the cost of water would increase from $2.89 per thousand litres to $3.39 per thousand litres.

    The price increase rewards people for saving water when it matters most. While there’s a low chance of the drought price being applied, a 15 per cent reduction in water use would fully offset the costs, if it were to be introduced. The price also reflects extra costs associated with delivering water during periods of drought such as higher treatment costs associated with the operation of the Tomago Sandbeds and increased water conservation initiatives.

IPART's final determination for prices

IPART has finalised its review of the prices we can charge for the water, wastewater and stormwater services provided to residential and non-residential customers. Learn more about the updated prices that commenced from 1 July 2020.
