Service charges for water and sewerage, including access charges.
Our water charging structure consists of two components, a water access charge and a water usage charge.
The estimated income for 2025-26 from the two charge components is shown below.
Income source | 2025-26 Estimate |
---|---|
Water access charge | $5,406,906 |
Water usage charge | $10,543,420 |
Total | $15,950,32 |
The water access charge (ACw) is charged annually to all residential and non-residential properties. It is determined by the water service connection size, according to the formula:
AC = AC20 x D2/400
The water access base charge (AC20) is defined by the size of a standard residential 20mm water service connection.
The water access base charge (AC20) for 2025-26 is shown below.
Charge | 2025-26 $/connection |
---|---|
Water accs base charge (AC20) | $315 |
These are considered separately below.
Strata title properties are charged the water access base charge for each rateable parcel of land created under a strata title subdivision, regardless of water service connection size, or the number of water service connections, according to the formula:
ACw = AC20 – applied to each rateable parcel of land created under a strata title subdivision.
Multiple residence properties, where individual separate dwellings are situated on a single parcel of land (including but not limited to non-strata flats/units/villas, secondary dwellings and dual occupancies) are charged a water access charge based on the number of dwellings, regardless of water service connection size, or the number of water service connections, according to the formula:
ACw = AC20 x ND
Residential retirement villages and multi-residence affordable housing properties are charged a water access charge for each water service connection with a discount factor applied, according to the formula:
ACw = AC20 x D2/400 x DF
The discount factor (DF) for 2025-26 is shown below.
Charge | 2025-26 |
---|---|
Discount factor | 0.85 |
Eligibility for the residential categorisation and discount factor is determined on an application basis:
Connected properties for non-residential non-rateable community organisations are charged the water access base charge with a discount factor applied, according to the formula:
ACw = AC20 x DF
The discount factor (DF) for 2025-26 is shown below.
Charge | 2025-26 |
---|---|
Discount factor | 0.85 |
Mixed-use developments
Connected properties rated as mixed-use for commercial and residential use are charged a water access charge based on the water service connection size and a water access base charge for each residential dwelling at the same site, according to the formula:
ACw = (AC20 x D2/400) + (AC20 x ND)
Examples of such premises include a shop with a dwelling at the rear or upstairs, a commercial premise incorporating shop-top housing, or a caretaker’s unit in an industrial area.
No water access charge applies to approved dedicated fire service connections. This exemption is forfeited if metered water usage occurs outside of emergency use. An access charge based on increments of the water access base charge will then apply.
Unconnected properties within 225 meters of a water main are charged an unconnected water access charge.
The unconnected water access charge for 2025-26 is shown below.
Charge | 2025-26 $/connection |
---|---|
Unconnected water access charge | $315 |
The water usage charge is a variable charge based on the volume of water used and metered through a property water meter in kilolitres (kL). It is charged four times a year, according to the formula:
UCw = Q x UC
The water usage charge rate (UC) for 2025-26 is shown below.
Charge | 2025-26 S/kL |
---|---|
Water usage charge rate (UC) | $3.95 |
Connected properties with home dialysis and home care medical patients may obtain an allowance for water use. We require certification by a medical practitioner for this allowance to apply.
Our sewerage charging structure consists of a single-part residential sewer access charge and a two-part non-residential sewer access and usage charge.
The estimated income for 2025-26 from the two charge components is shown below.

---|---|
Discount factor | 0.85 |
Eligibility for the residential categorisation and discount factor is determined on an application basis outlining:
The non-residential sewer access charge (ACNR) is charged annually to all connected non-residential properties. It is a charge based on the non-residential sewer access base charge, water supply service connection size and a sewer discharge factor, according to the formula:
ACNR = ACNRS x D2/400 x SDF – for each connected water service
The non-residential sewer access base charge (ACNRS) for 2025-26 is shown below.
Charge | 2025-26 $/connection |
---|---|
Non-residential sewer access base charge (ACNRS) | $1,589 |
The sewer discharge factor is a percentage of metered water use deemed to discharge to sewer. It applies to both non-residential access and usage. The percentage is based on guidance material for different property types provided to us by the NSW government.
These are considered separately below.
Connected properties for non-residential non-rateable community organisations are charged the non-residential sewer access base charge (ACNRS) multiplied by a discount factor, regardless of water service connection size, or the number of water service connections, according to the formula:
ACNR = ACNRS x DF
The discount factor (DF) for 2025-26 is shown below.
Charge | 2025-26 |
---|---|
Discount factor | 0.85 |
Connected properties rated as mixed-use for commercial and residential use are charged a non-residential sewer access charge and the residential sewer access base charge (ACRS) for each residential dwelling at the same site, according to the formula:
ACNR = (ACNRS x D2/400 x SDF) + (ACRS x ND)
Examples of such premises include a shop with a dwelling at the rear or upstairs, a commercial premise incorporating shop-top housing, or a caretaker’s unit in an industrial area.
Unconnected residential and non-residential properties within 75 meters of a sewer main are charged an unconnected sewer access charge.
The unconnected sewer access charge for 2025-26 is shown below.
Charge | 2025-26 $/connection |
---|---|
Unconnected sewer access charge | $795 |
The non-residential sewer usage charge is a variable charge for non-residential properties. It is determined by the volume of metered water use in kilolitres (kL) multiplied by a sewer discharge factor and a charge rate. It is charged four times a year, according to the formula:
UCNR = Q x SDF x UC
The non-residential sewer usage charge rate (UCNR) for 2025-26 is shown below.
Charge | 2025-26 S/kL |
---|---|
Non-residential sewer usage chargeate (UC) | $5.70 |
A non-residential sewer bill is determined according to the formula:
B = ACNR + UCNR
Liquid trade waste (LTW) is all liquid waste other than sewage of a domestic nature discharged to the sewerage system from non-residential properties. LTW adds additional cost to transporting and treating sewage. To recover these costs and to remove cross-subsidies from residential customers, fees and charges are applied to LTW dischargers. LTW fees and charges are in addition to non-residential sewer charges and include general fees and charges, category-specific usage charges and non-compliance charges.
LTW general fees and charges are included in our 2025-26 Fees and Charges document. They include:
LTW dischargers are divided into four categories for usage charging purposes. The four categories and formulas used for LTW usage charges are outlined below.
Category 1: LTW dischargers requiring nil or minimum pre-treatment
No usage charge applies.
Category 2: LTW dischargers with prescribed pre-treatment
The LTW usage charge for category 2 dischargers is calculated according to the formula:
LTW2 = Q x LTWDF x UC2
The LTW discharge factor is a percentage of metered water use deemed to discharge to sewer as LTW. The percentage applied is based on guidance material for different discharger types provided to us by the NSW government.
The category 2 LTW usage charge rate (UC2) for 2025-26 is shown below.
Charge | 2025-26 $/kL |
---|---|
LTW usage charge rate - category 2 (UC2) | $2.40 |
Category 2S: LTW dischargers that transport sewage waste to sewage treatment plants
This category includes transporters that tanker human waste to sewage treatment plants from septic tanks, portable toilets, pit toilets, on-site sewage management systems and ship-to-shore pump-out facilities.
LTW2s = Q2s x UC2s
The category 2S LTW usage charge rate (UC2s) for 2025-26 is shown below.
Charge | 2025-26 $/kL |
---|---|
LTW usage charge rate - category 2S (UC2s) | $20.00 |
Category 3: Large (<20 kL/d) and industrial LTW dischargers
The LTW usage charge for category 3 dischargers is calculated according to the formula:
LTW3 = EMC
Excess mass charges (EMC) are for large and industrial LTW dischargers that discharge LTW above ‘deemed concentrations’ in domestic sewage. EMCs are based on NSW Government advice in the Liquid Trade Waste Management Guidelines 2021. The unit charging rates ($/kg) for each substance are obtained from guidance material provided to Council by the NSW Government.
Non-compliance charges are included in our 2025-26 Fees and Charges document. Non-compliance charges are for dischargers that have not installed or maintained pre-treatment equipment, or complied with a notice to install or maintain pre-treatment equipment.
High usage charges are additional charges levied on non-residential customers who have used more capacity in our water and sewerage networks than previously paid for. Capacity is expressed in terms of a ‘credit volume’ for water used and sewage discharged in kL/y.
For existing non-residential connections, a credit volume is determined by either previous section 64 developer contributions paid, or a 10-year 80th percentile water use from 2010-2019, according to the formulas:
CVw = ET x 205 kL/y
CVs = ET x 190 kL/y
CVw = u + Zs
CVs = (u + Zs) x SDF
For new non-residential connections, a credit volume of 205 kL/y for water and 190 kL/y for sewer are allocated where developer contributions have been paid previously. Where contributions have not been paid, a minimum credit volume of 205 kL/y for water and 190 kL/y for sewer must be purchased at rates within our 2025-26 Fees and Charges document.
High usage charges apply for water used and sewage discharged beyond the credit volumes assigned to a non-residential property. High usage charges are charged annually following the final water meter read in a financial year, according to the formulas:
HUCNRW = Q x HUCW
HUCNRS = Q x SDF x HUCS
The high usage charge rates for 2025-26 are shown below.
Charge | 2025-26 $/kL |
---|---|
High usage charge rate water (HUCW) | $3.00 |
High usage charge rate sewer (HUCS) | $4.54 |
The high usage charge rates are re-calculated annually. A net present value calculation is used where the developer charges for water and sewer are discounted over 30 years with a rate equal to the IPART Local Government Discount Rate (3.5% in December 2024).
Additional credit volumes can be purchased at any time at the section 64 developer contribution rate shown in our 2025-26 Fees and Charges document. No additional credit volumes will accrue through payment of the high usage charge.
Council will charge a single annual amount on rates and charges notices which helps fund OSM program required to manage the risk that onsite sewage management systems pose to human health and the environment. Program services include routine inspections of systems based on risk classification, inspections of voluntary upgrades to systems, administration, and advice/education.
Separate fees will still apply for Section 68 Approval to Install/Alter Systems of Onsite Sewage Management, and inspections of new systems.
Estimated income for On-Site Sewer Management in 2025-26 is $326,468. (Sec 608 [2])
Risk Category | Charge |
---|---|
OSM - Low risk (10 year cycle) | $47.00 |
OSM - High risk (3 year cycle) | $83.00 |
OSM - Critical risk 1 year cycle) | $185.00 |
