Parkes Shire Council is committed to investing in a sustainable water future. From mid- 2022 onwards, we will be upgrading existing water infrastructure and adding additional water supply assets to preserve, protect and sustainably manage our key water sources.

Council’s water supply network is ageing and needs to be upgraded. Parts of our water supply network pipework is leaking and many of our bores are over 50 years old which affects our ability to efficiently extract, treat, pump, store and supply water through the existing water supply network. Currently, we can only supply around 70% of our total water capacity. Climate change forecasts predict that rainfall will decline, while severe fires and extreme weather events are likely to increase, affecting demand for water in a changing climate.

Parkes Shire Council has secured funding worth approximately $65M from State and Federal government sources as well as accumulating our own reserves.  This includes state government funding from the Safe and Secure Water Program ($22M), Critical Drought Relief - Restart NSW Fund ($3.4M) and Department of Planning and Environment ($600k), and federal government funding from the Building Better Regions ($6M) and Regional Recovery Partnerships ($5M). The project is fully funded and will not impact water rates and charges.

 

The Parkes Water Security Program involves a package of current construction projects to ensure Parkes Shire has a reliable water supply to meet forecast demand.

Lachlan River Pump Station Augmentation

The works for the Lachlan River Pump Station (LRPS) Augmentation include:

  • The replacement of the existing LRPS intake screen to provide a higher inlet capacity,
  • The removal of two existing pumps, and installation of three replacement pumps,
  • The installation of new pipes, valves, rising main, and electrical cabling to support the additional pump, and
  • The augmentation of the above ground power line.

Lachlan River Pre-Treatment Plant

The Lachlan River Pre-Treatment Plant (LRPTP) will be located on Council-owned land, approximately 12km east of the township of Forbes on The Escort Way in the Forbes Local Government Area. 

The new LRPTP will allow Council to pre-treat raw water from the Lachlan River before being transferred to the Water Treatment Plant in Parkes.

The pre-treatment process will reduce water turbidity and remove suspended impurities and solids from the raw water. The construction of two sediment lagoons will provide additional water treatment capacity.

A Review of Environmental Factors(PDF, 8MB)  was carried out to assess any potential environmental impacts associated with this project. An Addendum(PDF, 18MB)  was also prepared to supplement this review. 

Raw Water Storage Lagoon

An additional 20ML of raw water storage upstream of the Water Treatment Plant.

Benefits

  • Additional water storage for future growth
  • Increases raw water storage to manage drought conditions
  • Allows for the transfer and treatment of raw water during energy off-peak times

New Pump Stations

Two new pump stations, one on Eugowra Road and the other on Akuna Road.

Benefits

  • The new pump station at Eugowra Road will receive raw water from the Parkes Shire bores
  • The Lachlan River Pump Station will treat the water and pump it to the Akuna Road Pump Station.
  • Akuna Road Pump Station will receive raw water from the Eugowra Road pump station
  • Pump stations will increase our raw water extraction within our current water supply entitlement

Lachlan Pipeline Duplication

Duplication of 35km of raw water transfer pipeline from Eugowra Road Pump Station to the Parkes Water Treatment Plant.

Benefits

  • Duplication of existing pipelines to improve water quality and quantity
  • Efficiently transport water to meet future water demand for growing townships
  • Reduces water lost to leaking pipes and ageing water supply infrastructure

Additional Bore and Bore Refurbishments

The refurbishment of existing bores 1,3,4 & 5, site investigation for an additional Lachlan aquifer bore and the development of under bores for planned future pipelines.

Benefits

  • The sustainable management of the Lachlan aquifer by spreading the water take across a wider area. The additional bore will be located away from existing bores to promote a more sustainable yield.
  • Increased efficiency in supplying raw water to the pump stations.

Solar Energy Systems

Sustainable energy to power key water security assets.

Benefits

  • Solar energy systems provide sustainable energy to the new pump stations at Eugowra Road and Akuna Road
  • Reduces energy costs and provides operational flexibility and reliability
  • Sustainable energy offsets costs for the sediment ponds and water treatment plant at the Lachlan River
  • Water transfer in the off-peak electricity periods or during daylight hours
  • Reduces Council’s carbon footprint
