Council's Water and Sewer Responsibilities
Expand the sections below for information on the range of legislative requirements, obligations and responsibilities of Dubbo Regional Council related to water and sewer.
WATER USAGE
2023/2024 - Water usage compared to permitted water usage (PDF 9.3KB)
The solid red line shows the cumulative water consumption that would just meet Dubbo's existing water extraction licences. So that the City does not exceed the existing licence limits, the City water extraction must stay "below" this line. The actual cumulative City water extraction each month is shown by the dotted line.
WATER SUPPLY SERVICES POLICY
Council's Water Supply Services Policy deals with water connections from Council's water reticulation network supplying drinking water onto the property of the water supply customer. The policy also includes information on water meters, fire services, backflow prevention, water theft, technical administration, pricing and charges. It can be viewed at Council's dedicated webpage; A-Z Council Policies.
The fact sheets for the former Dubbo (PDF 1.3MB) and Wellington (PDF 1.4MB) regions provide an overview of frequently asked questions on water connection, types of services, water meters, water service access and usage charges.
The Water Responsibility (PDF 650.3KB) fact sheet provides information on your and Council's responsibility for water supply services.
ENVIRONMENTAL DISCHARGE MONITORING
WATER TREATMENT PLANTS
Dubbo Regional Council's Water Treatment Plants are licenced by the NSW Environment Protection Authority, and backwash water discharged to the Macquarie River must be monitored in accordance with the terms of the licences.

POLLUTION INCIDENT RESPONSE MANAGEMENT PLAN (PIRMP)
Council has developed Pollution Incident Response Management Plans that will guide Council's response in the event of any pollution incidents that may occur at the John Gilbert Water Treatment Plant (PDF 437.4KB), Wellington Water Treatment Plant. (PDF 579KB), Dubbo Sewer Treatment Plant (PDF 585.6KB) and Wellington Sewer Treatment Plant (PDF 591.7KB).
WATER MANAGEMENT AND SUPPLY
Council is responsible for providing a safe, reliable and cost effective drinking water supply which is customer focused, enhances the local area environment, and caters for the sustainable growth in the Dubbo Regional Council area.
WATER SOURCES
Council owns and operates its own water supply system and sources its potable water supply from the Macquarie River (100% for Wellington area) and for the Dubbo area the Macquarie River (typically 70%) and a total of 7 bores within the South Dubbo borefield (typically 30%). The water from is treated at the Wellington Water Treatment Plant and John Gilbert Water Treatment Plant (respectively) before being pumped to service reservoirs throughout the Wellington area and Dubbo area including the villages of Ballimore, Brocklehurst, Eumungerie, Mogriguy and Wongarbon.
MANAGEMENT OF WATER RESOURCES
The Drought Contingency and Water Emergency Response Plan (DCWERP) was prepared to ensure the community recognises the issues associated with drought management and their role in supporting Council's actions during drought or emergency incidents and a strategic mechanism for managing water supply in the Dubbo Local Government Area (LGA) during periods of drought or emergency incidents.
The DCWERP has been prepared to replace previous plans issued for both former Dubbo City and Wellington Council's.
The plan also includes:
- Clear protocols to assist Council in its decision making and governance processes during drought events.
- Emergency management processes and the appropriate high level responses.
- Incorporation of NSW State Government Audit feedback from the Drought Management Plan 2015.
- Integration of concerns identified in the NSW Advisory Integrated Water Cycle Management Issues Paper 2019.

OPERATIONAL ENVIRONMENTAL MANAGEMENT PLAN FOR WATER SUPPLY
Council supply treated water to the City of Dubbo and surrounding local government area, servicing a residential population of approximately 40,491 of which 34,130 are connected to the reticulated water supply. Water is sourced from a licensed intake on the Macquarie River and a borefield located in South Dubbo, and treated at the John Gilbert Water Treatment Plant prior to being pumped to service reservoirs throughout the urban areas of Dubbo.
An Operational Environmental Management Plan has been prepared to document the following:

WATER ENTITLEMENT MANAGEMENT AND TRADING STRATEGY
Council's Water Entitlement Management and Trading Strategy helps guide future urban water supply planning to ensure:
- Dubbo's long term security of water supply
- Efficient management of water entitlements
- Recognition that water entitlements are valuable community assets
- Effective water purchases and trading activities
- Transparency and accountability in water trading activities.
For a copy of our Water Entitlement Management Trading Strategy, please contact us.
Council is currently developing a process for selling unwanted water licences. Council's water trading process will be available on the website once plans are completed.
INTEGRATED WATER CYCLE MANAGEMENT PLAN
The NSW Government has strongly encouraged Councils to undertake Integrated Water Cycle Management planning for some time now.
The NSW Department of Planning, Industry, and Environment (formerly the Department of Water and Energy) published "Best Practice Management of Water Supply and Sewerage Guidelines" in August 2007 which recommended six areas of best practice:
- Strategic Business Planning
- Pricing and Developer Charges (including Liquid Trade Waste Approvals)
- Demand Management
- Drought Management
- Performance Reporting
- Integrated Water Cycle Management (IWCM)
Items 1 - 5 have been addressed in the past.
The IWCM process required extensive input from Council staff and the wider community.
For a copy of Council's IWCM, please contact us.
* A number of strategies are in place across different functions of Council. However, only strategies that have been adopted by the new Dubbo Regional Council will be available on the A - Z plans and strategies page.
SEWAGE TREATMENT AND MONITORING
Learn more about sewage treatment and monitoring by Dubbo Regional Council.
OPERATIONAL ENVIRONMENTAL MANAGEMENT PLAN FOR SEWERAGE SERVICES
Council provides sewerage reticulation and treatment services to 32,537 Dubbo residents and 687 Wongarbon residents. Sewage is transferred from the residential properties, through a series of pipelines and pump stations to the Dubbo and Wongarbon Sewage Treatment Plant.
An Operational Environmental Management Plan (PDF 1MB) has been prepared to document the following:
- Regulatory requirements
- Management system components including reporting, document control, training, complaints and review, and
- Environmental risk identification, monitoring and management strategies associated with the sewer operations.
SEWAGE TREATMENT
The following table indicates some parameters of sewage received at the Dubbo Sewage Treatment Plant, called "influent", and the quality of the water after treatment, when it leaves the plant, called “effluent”.

The unit “cfu/100 mL” refers to the number of colony forming units in a 100 millilitre sample. It is a biological measure of viable bacterial cells in the water.
Electrical conductivity is measured in units of micro Siemens per centimetre (µS/cm). It is an indication of the amount of nutrient, impurities or salts in solution.
