1 Introduction
Section 64 of the Local Government Act 1993 enables a local government council to levy developer charges for water supply, sewerage and stormwater. This derives from a crossreference in that Act to Section 306 of the Water Management Act 2000
A Development Servicing Plan (DSP) details the water supply, sewerage and/or stormwater developer charges to be levied on development areas utilising a water utility’s water supply, sewerage and/or stormwater infrastructure.
This DSP covers water supply and sewerage developer charges for areas served by MidCoast Council (Council).
This DSP has been prepared in accordance with the 2016 Developer Charges Guidelines for Water Supply, Sewerage and Stormwater issued by the Minister for Lands and Water, pursuant to Section 306 (3) of the Water Management Act 2000
This DSP document supersedes any other requirements related to water supply and sewerage developer charges for the areas covered by this DSP. This DSP takes precedence over any of Council’s code or policies where there are any inconsistences relating to water supply and sewerage developer charges.

7 Developer Charges Calculation – Water Supply
All new properties and properties with change in use which are subject to payment of water supply charges are liable for payment of developer charges for water supply. An ET is the basic unit to determine the demand that the development will place on the water supply system. One ET represents the equivalent demand from a single, detached residential dwelling.
Credit for existing use is applied in the calculation of the ET loadings, as the developer charges are levied for additional ET loading only. For example, the first lot in a residential subdivision is exempt from developer charges where the lot is already connected to the water supply system. Properties not already rated for water supply do not receive the one lot credit.
7.1 Summary
The developer charges for the areas covered in this DSP document are summarised in Table 3.
Table 3: Summary of Proposed Water Supply Developer Charges for Water Supply
7.2 Service Areas
The water supply service areas and the basis of determining the service areas are presented in Table 4
Table 4: Basis of Determining Water Supply Service Areas
Bulahdelah Area serviced by a separate water supply distribution system. Gloucester Area serviced by a separate water supply distribution system. Manning Area serviced by a separate water supply distribution system.
North Karuah A separate town or village (supplied with water from Hunter Water).
Tea Gardens Area serviced by a separate water supply distribution system.
Stroud Area serviced by a separate water supply distribution system
7.3 Equivalent Tenements
For each service area, the current number of serviced ETs is estimated as the total annual water supplied to the service area divided by average residential water consumption. Average annual residential water consumption varies across each service area, ranging from 120 to 140 kL/property/yr.
The number of future ETs was estimated based on population projection data from forecast.id, as well as information on known growth areas. For future ETs, average water consumption was assumed to be 185 kL/ET/yr as recommended by Council’s AUS-SPEC guidelines (AUS-SPEC 2022 Infrastructure Specifications 0071 Water Supply – Reticulation (Design)).
ET projections for each service area are shown in Table 5. The ETs in January 1996 are also provided. There were no projected additional ETs for North Karuah and so these have not been shown and, subsequently, there are no further calculations for North Karuah.
Table 5: ET Projections for Water Supply
ET calculation details for each service area are shown in Section 14
7.4 Capital Charge
The capital charge for each service area covered by this DSP document has been calculated using the NPV spreadsheet method.
Under the NPV spreadsheet method, the capital cost of relevant assets and projected ETs served in a service area are entered into a spreadsheet. These capital costs are only for the share of the asset capacity used in the service area. The PV of capital cost and the PV of new ETs are calculated, and the capital charge per ET is the PV of the capital cost divided by the PV of the ETs. A 3% discount rate was applied for pre-1996 infrastructure and a 5% discount rate was applied to post 1996 and future assets, in accordance with the DPI guidelines.
Calculation details for PV of ETs and PV of capital costs for each service area are shown in Section 17. The summary of the capital charge calculations is shown in Table 6
DSP Area
Table 7 shows the agglomeration of service areas into DSP areas of within 30% of the highest capital charge.
• Gloucester and Bulahdelah service areas are agglomerated into a single DSP area (Area A) as the Bulahdelah capital charge is within 30% of the Gloucester capital charge.
• Stroud, Manning and Brimbin service areas are agglomerated into a single DSP area (Area B) as the Manning and Brimbin capital charges are within 30% of the Stroud capital charge.
Table 6: Capital Charge Calculation for Water Supply
Table 7: Agglomeration of Service Areas for Water Supply
Weighted average capital charge for each DSP area is calculated by weighting by the PV of new ETs in each service areas. The calculation is shown in Table 8.
Table 8: Weighted Average Capital Charge for Water Supply
7.6 Reduction Amount
MidCoast Council has adopted the NPV of Annual Bills method to calculate the Reduction Amount. This method involves calculation of the PV of the future net income, which is the difference between the revenue from annual bills, and annual OMA cost, projected for new development over the next 30 years. This is divided by the PV of the new ETs over 30 years to give the reduction amount. The reduction amount calculations are shown in Table 9. The annual bill and OMA costs were calculated using data from the Special Purpose Financial Statements - Income Statement of water supply business activity and the Local Water Utility performance monitoring data submitted to DCCEEW for the year ended June 2024 and are summarised below.
Annual bill at the commencement of the DSP = $828 per ET
OMA Cost at the commencement of the DSP = $610 per ET
Net income = Annual bill – OMA cost = $218 per ET
Table 9: Calculation of the Reduction Amount for Water Supply
Calculation details for reduction amount are shown in Section 18.
7.7 Cross-Subsidy
The cross-subsidy is the difference (%) between the annual bill with the calculated maximum developer charge and the proposed lower developer charge.
LWUs may elect to cap the developer charges for small villages in order to maintain affordability and to avoid ‘stranded’ assets in such villages. LWUs may also cap other developer charges to maintain affordability, subject to adopting a commercial developer charge which recovers a significant proportion of the capital cost of the infrastructure.
The cross-subsidy, resulting from capping of developer charges must be disclosed in the DSP and in communication materials for consultation with stakeholders as noted above.
It is proposed that MidCoast Council does not apply a cross subsidy (Option 1) for water supply to reduce the water developer charges in Gloucester and Bulahdelah Applying a cross subsidy, under Option 2, would result in average annual water bills increasing by $112.69 or approximately 14% across the LGA (refer to Table 11).
Two options were developed and examined as follows:
• Option 1 - No cross subsidy
• Option 2 - Cross subsidy (AB)
A summary of the developer charge options and cross-subsidies are shown in Table 10.
Table 10: Developer Charge Options and Cross-Subsidy for Water Supply
Option 2 - Cross subsidy (AB)
The impact of the cross-subsidy options on the annual water supply bill are summarised in Table 11

8 Developer Charges Calculation – Sewerage
All new properties and properties with change in use which are subject to payment of sewerage charges are liable for payment of developer charges for sewerage. An ET is the basic unit to determine the loading that the development will place on the sewerage system. One ET represents the equivalent loading from a single, detached residential dwelling.
Credit for existing use is applied in the calculation of the ET loadings, as the developer charges are levied for additional ET loading only. For example, the first lot in a residential subdivision is exempt from developer charges where the lot is already connected to the sewerage system. Properties not already rated for sewerage do not receive the one lot credit.
8.1 Summary

8.3 Equivalent Tenements
For each service area, the current number of serviced ETs is estimated as the total annual water supplied to the service area divided by average residential water consumption. Average annual residential water consumption varies across each service area, ranging from 120 to 140 kL/property/yr.
The number of future ETs was estimated based on population projection data from forecast.id, as well as information on known growth areas. For future ETs, average loadings were calculated as outlined in Council’s AUS-SPEC guidelines (AUS-SPEC 2022 Infrastructure Specifications 0076 Sewerage Systems – Reticulation (Design)).
ET projections for each service area are shown in Table 14. The ETs in January 1996 are also provided. There were no projected additional ETs for North Karuah and so these have not been shown and, subsequently, there are no further calculations for North Karuah.
Table
ET calculation details for each service area are shown in Section 14.
8.4 Capital Charge
The capital charge for each service area covered by this DSP document has been calculated using the NPV spreadsheet method.
Under the NPV spreadsheet method, the capital cost of relevant assets and projected ETs served in a service area are entered into a spreadsheet. These capital costs are only for the share of the asset capacity used in the service area. The PV of capital cost and the PV of new ETs are calculated, and the capital charge per ET is the PV of the capital cost divided by the PV of the ETs. A 3% discount rate was applied for pre-1996 infrastructure and a 5% discount rate was applied to post 1996 and future assets, in accordance with the DPI guidelines.
Calculation details for PV of ETs and PV of capital costs for each service area are shown in Section 17. The summary of the capital charge calculations is shown in Table 15.

This is divided by the PV of the new ETs over 30 years to give the reduction amount. The reduction amount calculations are shown in Table 18. The annual bill and OMA costs were calculated using data from the Special Purpose Financial Statements - Income Statement of sewerage business activity and the Local Water Utility performance monitoring data submitted to DCCEEW for the year ended June 2024 and are summarised below.
Annual bill at the commencement of the DSP = $1140 per ET
OMA Cost at the commencement of the DSP = $728 per ET
Net income = Annual bill – OMA cost = $412 per ET
Table 18: Calculation of the Reduction Amount for Sewerage
Calculation details for reduction amount are shown in Section 18.
8.7 Cross-Subsidy
The cross-subsidy is the difference (%) between the annual bill with the calculated maximum developer charge and the proposed lower developer charge.
LWUs may elect to cap the developer charges for small villages in order to maintain affordability and to avoid ‘stranded’ assets in such villages. LWUs may also cap other developer charges to maintain affordability, subject to adopting a commercial developer charge which recovers a significant proportion of the capital cost of the infrastructure.
The cross-subsidy, resulting from capping of developer charges must be disclosed in the DSP and in communication materials for consultation with stakeholders as noted above.
It is proposed that MidCoast Council applies a cross subsidy (Option 2) to reduce the sewer developer charges in Lansdowne to be the same as the calculated charge for DSP Area B (which covers Bulahdelah, Tea Gardens, Manning Point, Wingham, Forster, Coopernook, Hawks Nest, and Stroud). The rationale for applying the cross subsidy is to maintain affordability in villages and small towns. This cross-subsidy option results in an increase of $0.47 or 0.04% to the average annual sewerage bill across the LGA.
Three options were developed and examined as follows:
• Option 1 - No cross subsidy
• Option 2 - Cross subsidy (AB)
• Option 3 - Cross subsidy (ABC)
A summary of the developer charge options and cross-subsidies are shown in Table 19.
Table 19: Developer Charge Options and Cross-Subsidy for Sewerage
The impact of the cross-subsidy options on the annual sewerage bill are summarised in Table 20.
Table 20: Impact of Cross-Subsidies on Annual Sewerage Bill
9 Reviewing/ Updating of
Developer Charges
Developer charges will be adjusted on 1 July each year based on movements in the CPI for Sydney, in the preceding 12 months to December, excluding the impact of GST.
Developer charges will be reviewed by Council after a period of 4 to 8 years.

MEERA Modern Engineering Equivalent Replacement Asset. An asset value calculated on the basis that the asset is constructed at the time of valuation in accordance with modern engineering practice and the most economically
viable technologies, which provides similar utility functions to the existing asset in service.
ML Megalitre (1,000,000 litres, or 1,000 kilolitres).
Net income Annual bill minus OMA cost per ET.
NPV
Net present value means the difference between the Present Value of a revenue stream and the Present Value of a cost stream.
