Orange's Raw Water Supply System


The Orange Raw Water Supply System is the name used for managing the sources of untreated 'raw' water for the community of Orange.

It includes :

  • Spring Creek and Suma Park dams
  • the Blackmans Swamp Creek stormwater harvesting scheme
  • the Ploughmans Creek stormwater harvesting scheme
  • Water supply bores
  • the Macquarie River to Orange Pipeline



Management Plan

A document has been developed which will help ensure that the envionmental 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 for the Orange Raw Water Supply System (OEMP) was formally approved by the NSW Department of Planning and Environment on 7 September 2016. Here is the formal Letter of Approval.

The OEMP is a large document. It can be downloaded from these links in its component parts.

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.

The quarterly reviews of the DST contain the Current Operating Rules.

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, such as this Decision Support Tool Second Quarterly Review produced in February 2017.

Statement of Conditions – Water Access Licences

The Orange Raw Water Supply system operates under a number of NSW Government-issued water licences.


Stream Gauges

A number of stream gauging stations provide information about the amount of water at key points in local river systems. These include :

  • Station 421192 Macquarie River downstream of Long Point (Pump offtake point)
  • Station 421185 Summer Hill Creek at Icely Road and
  • Station 421197 Summer Hill Creek at Third Crossing bridge
  • Station 421051 Blackmans Swamp Creek at the Sewage Treatment Plant 
  • Station 421186 Ploughmans Creek at North Orange 1 Sewage Pump Stati

Data from these stream gauge sites is managed by DPI Water and is available at http://realtimedata.water.nsw.gov.au
