Water services - Supply charges

Council collects revenue from the people who benefit from access and use of our water supply - our customers. Customers are charged in two parts - an annual fixed water access charge and a variable water usage charge based on metered use.

Income source	2024-25 Estimate
Water access charge	$5,111,899
Water usage charge	$9,080,181
Total	$14,192,080

 

Water access charges

The water access base charge (AC20) is for a 20mm connection to our water supply system. This is the standard residential meter size.

Connection Type	Charge
20mm water connection, strata title (per unit), unconnected properties able to connect (e.g vacant land)	$300
Water access base charge (AC20)	$300

 

Access charges for larger water connections (AC) are based on increments of the base charge according to the following formula: AC = AC₂₀  x  D²/400

• AC = Water access charge - connections larger than 20mm ($)
• AC₂₀ = Water access base charge ($)
• D = Meter size (mm)

The water access charge is shown on the annual rate notice and is independent of water usage.

All approved dual occupancy and secondary dwellings will attract a minimum of 2 water access charges and 2 sewer access charges.

Non-rateable community organisation water access

Water access charge for non-rateable community assessments equal to the 20mm non-residential water access charge applied per assessment regardless of meter size.

Water usage charge

The water usage charge for 2024-25 is $3.77 per kilolitre. Water usage is charged four times a year based on actual meter readings.

Allowances

An allowance may apply to home dialysis and home care medical patients. Council requires certification by a medical practitioner and registration with Council for this allowance to apply. Properties with an approved dedicated fire service will have no water access charges applied. If metered water usage occurs outside of emergency use, this exemption will be forfeited.

Sewerage services - supply charges

Council collects revenue from the people who benefit from access to our sewerage infrastructure – our customers.

Income source	2024-25 Estimate
Sewer access charge	$21,145,20
Sewer usage charge	$2,338,665
Total	$23,483,885

 

Residential sewerage charges

Residential sewerage is charged through a single fixed cost. There is no usage charge.

Connection Type	Charge
Residential sewerage Residential strata and non- strata sewerage	$1,515
Unconnected properties able to connect	$758

 

Non-rateable community organisation sewer access

Non-rateable community assessments charge is based on a non-residential 20mm connection with a 95% discharge factor to be charged per assessment.

Non-residential sewerage charges

Non-residential customers are charged in two parts. An annual fixed sewerage access charge and a variable sewer usage charge. Sewer use is based on metered water use, and a sewer discharge factor for your property type

Council has adopted this charging structure based on NSW Government advice which can be found in Liquid Trade Waste Management Guidelines 2021, Chapter 8 – Non-residential sewerage and liquid trade waste fees and charges.

Non-residential sewerage access charge

Connection Type	Charge
Non-residential sewerage Non-residential strata and non-strata sewerage	$1,515
Unconnected properties able to connect	$758
Non-residential sewerage access base charge (ACs20 )	$1,515

 

Sewerage access charges are linked to the size of your water connection. Charges for larger water connections (ACS) are based on increments of the base charge according to the following formula:

AC_s = AC_s20 x D²/400

• AC_s = Non-residential sewerage access charge ($)
• AC_s20= Non-residential sewerage access base charge ($)
• D = Water supply service connection size (mm)

Non-residential sewerage usage charge

The non-residential sewerage usage charge for 2024-25 is $5.47 per kilolitre.

Sewer discharge factor (SDF)

The sewer discharge factor is a percentage of metered water usage deemed to discharge to sewer. The percentage applied is based on guidance material for different property types provided to us by the NSW Government.

Working out your total non-residential sewerage bill

A non-residential sewerage bill is worked out from this formula:

B= SDF x (AC_s + Q_w x UC)

• B = Annual non-residential sewerage bill ($)
• SDF = Sewerage discharge factor
• AC_s = Non-residential sewerage access charge ($)
• Q_w = Your annual water consumption (kL)
• UC = Sewer usage charge ($/kL)

Liquid trade waste - charges

Liquid trade waste (LTW) discharged to the sewerage system from non-residential customers impose additional costs on transport and treatment facilities. To recover these costs and to remove cross-subsidies from residential customers, fees and charges are levied to LTW dischargers. LTW fees and charges are in addition to non-residential sewerage charges and include general fees and charges and category-specific usage charges.

General fees and charges

These are included in our fees and charges document. They include application fees, inspection fees and non-compliance charges.

Category specific charges

LTW dischargers are divided into four categories for charging purposes. The four categories and calculations used for LTW billing are outlined below.

Category 1: LTW dischargers requiring nil or minimum pre-treatment

No usage charge.

Category 2: LTW dischargers with prescribed pre-treatment

LTW₂ = A₂ + Q_LTW x C₂

• LTW₂ = LTW bill for category 2 dischargers
• A₂ = Annual LTW fee for category 2
• Q_LTW = Total LTW discharge volume (kL)
• C₂ = LTW usage charge $2.25 per kilolitre

The LTW discharge volume QLTW is estimated by applying a LTW discharge factor (LTWDF) to the total water consumption. The percentage applied is based on guidance material provided to Council by the NSW Government.

Category 2S: Transported sewage waste, dump points and ship-to-shore pump-outs

This category includes human waste tankered to sewage treatment plants from septic tanks, ablution blocks, portable toilets, pit toilets and sludge from on-site aerated sewage management systems. It also includes waste from dump points and ship-to-shire pump-out facilities.

LTW_2s = Q_2s x C_2s

• LTW_2s = LTW bill for category 2S dischargers
• Q_2s = Total LTW discharge volume (kL)
• C_2s = LTW usage charge $20.00 ($/kL)

Dump point owner/operators are only required to pay the annual fee A2s.

Category 3: Large (<20 kL/d) and industrial LTW dischargers

LTW₃ = EMC

• LTW₃ = LTW bill for category 3 dischargers
• EMC = Excess mass charges ($)

Excess mass charges (EMC) are for discharges above the ‘deemed concentrations’ in domestic sewage. EMCs are based on NSW Government advice which can be found in 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

Category 1  dischargers that have not installed or maintained pre-treatment equipment or complied with a notice to install or maintain pre-treatment equipment, may be charged a non-compliance charge using the usage charge formula for category 2 dischargers.

Category 2 dischargers that have not installed or maintained pre-treatment equipment or complied with a notice to install or maintain pre-treatment equipment may be charged a non-compliance charge of nine (9) times the usage charge (C2).

Category 3 discharges that fail to comply with acceptance limits in approval conditions may be charged noncompliance EMC’s using the formulas provided in the Liquid Trade Waste Management Guidelines 2021.

Supply charges - high usage

The high usage charge is a charge that replaces up-front Section 64 water and sewer developer charges. The charge instead incurs a higher rate per kilolitre (kL) for water used and sewage discharged where annual usage exceeds credit volumes established for each non-residential property. One equivalent tenement (ET) credit volume for water is 205 kL/y and for sewer is 190 kL/y.

Existing non-residential properties that are being redeveloped will be assessed for water and sewer ET loads using an assessment of historical water use to establish credit volumes for water and sewer. Previously paid section 64 contributions will be included when establishing credit volumes for the redeveloped property.

Credit volumes for new non-residential developments will be based on section 64 developer contributions paid on the property.

No additional credit volumes will accrue through payment of the high usage charge. Additional credit volumes can be purchased at any time at the section 64 developer contribution rate.

The high usage charge rates are re-calculated annually. A net present value calculation is used where the developer charges for water and sewer which are discounted over 30 years with a rate equal to the IPART Local Government Discount Rate (3.2% in January 2024).

High usage charges non-residential	Charge
Water	$2.75
Sewer	$4.16

 

Mixed Use Development Water and Sewer Charges

Where a property includes both a commercial and residential component, the following charges shall be made:

• Commercial water and sewerage access charges, and
• Separate water and sewerage access charges for each residential occupancy at the same site.

Examples of such premises include a shop with a dwelling at the rear or upstairs, a premise incorporating shop top housing, or a caretaker’s unit in an industrial area.

Supply charges - on-site sewer management

Council charges for the administration of the Shire’s existing On-Site Sewer Management network. Council will continue to charge a single annual amount for all existing On-Site Sewer Management.

Estimated income for On-Site Sewer Management in 2024-25 is $303,838.

Risk Category	Charge
Low risk (10 year cycle)	$44.00
Low risk (3 year cycle)	$79.00
Critical risk (1 year cycle)	$175.00
