The city of Orange draws its water from a number of sources.
The Orange Raw Water Supply System is the industry standard term that describes these different sources of untreated ‘raw’ water and how they are managed by the Council to be used by the community of Orange.
- the natural catchments of Suma Park, Spring Creek and Gosling Creek dams
- the Blackmans Swamp Creek and Ploughmans Creek stormwater harvesting schemes
- the Macquarie River to Orange Pipeline
- Underground water bores
HOW MUCH WATER IS ORANGE CURRENTLY USING?
This graph shows the average daily water consumption of residential households (expressed in litres per person per day) in the Orange City Council area. The light shaded areas provide a comparison of water usage during the corresponding three months of 2020 and 2021. The target water usage under the current Permanent Water Saving Standards is 180 litres per person per day.

PREVIOUS MONTHLY AVERAGES
Orange City Council has developed a plan aimed at ensuring that the environmental requirements and commitments made during the approvals process for the Macquarie River to Orange pipeline as well as other relevant licensing conditions, are implemented, monitored and reviewed as Orange’s (raw) water supply system is operated.
The Operation Environmental Management Plan (OEMP) for the Orange Raw Water Supply System was formally approved by the NSW Department of Planning and Environment on 7 September 2016. Here is the formal Letter of Approval.
The latest version of the OEMP Orange Raw Water Management Plan from June 2018 is available here.
The OEMP is a large document. It can be downloaded from these links in its component parts.
It’s intended that the OEMP will be reviewed each year. The following document is the fourth annual review of the OEMP.
Decision Support Tool
Part of the OEMP, the Decision Support Tool (DST) is a document which determines how the raw water supply system will be operated, year to year, and particularly which sources of water will be used.
Using this document to guide its meetings, a water management team meets every three months to review a number of factors including :
- climatic conditions
- water supply levels
- potential water sources
The group then recommends the mix of water sources to be used.
After each meeting, this team produces a report – Decision Support Tool Quarterly Report April 2021
An annual analysis of the year ahead has been completed – Decision Support Tool Water Year report 2020-21
The quarterly reviews of the DST contain the Current Operating Rules.
Water Access Licences (Statement of Conditions)
The Orange Raw Water Supply system operates under a number of NSW Government-issued water licences. These documents include the conditions that govern how water from each source may be used.
Integrated Water Cycle Management Plan
Integrated Water Cycle Management (IWCM) is a planning process developed by the NSW Department of Planning, Industry and Environment – Water (DPIE Water), with defined steps to effectively integrate water supply, sewerage and stormwater to achieve sustainable management of these services. The Orange IWCM Evaluation Study has followed these guidelines.
IWCM is a way of managing water in which all components of the water system are integrated so that water is used optimally. For a local water utility such as Orange City Council (OCC), this means that the three main urban water services – water supply, sewerage and stormwater – should be planned
and managed in an integrated way to ensure that the maximum value is obtained from the resources and that benefits to the environment and community are realised.
IWCM deals with the complex linkages between the different elements of the water cycle. It addresses issues facing local water utilities as well as the more general issues facing the environment. IWCM considers issues such as:
- The future urban water service needs and customer expectations;
- The availability of water including water sources such as surface water, groundwater, rainwater, effluent and stormwater; and
- The impact of water, sewerage and stormwater on other water users including the environment and future generations.
Ever wondered how water from different sources, finds its way into Orange’s main water supply storage dam, Suma Park Dam? And, how it gets to your home?
And then what happens to the waste water after it leaves your home?
The water in the dam is pumped to the water treatment plant or, released as an environment flow, into Blackmans Swamp Creek, downstream of the dam.
After leaving the treatment plant, water flows into reservoirs around Orange through pipes and then to residents’ homes and businesses.
A network of sewers then takes waste water to the Sewerage Treatment Plant before the treated effluent is used by the mining industry or returned to the environment.
WATER SUPPLY STORAGE LEVELS
The combined storage of Suma Park and Spring Creek Dams.
The combined storage of Suma Park and Spring Creek Dams is currently 100%.
