Project Announcement – Mt Walker (Mt Roe Dam) Chlorine Dosing Upgrades, WA


WestWater have successfully won a tender with the Water Corporation for the design, construction, installation and commissioning of upgrades to the Chlorine Dosing System at the Mt Roe Dam in Mt Walker, WA. Mt Walker is a small rural town located approximately 300km east of Perth, in Western Australia’s Wheatbelt region.

The following new equipment will be installed onsite during these upgrades:

  • Hyprolyser Electrochlorinator with water chiller and softener.
  • Hydrogen Gas Leak Detector.
  • Sodium Hypochlorite Storage Tank and Bund, with level transmitters and level switches.
  • Prominent Chlorine Analyser and water recovery system.
  • Magnetic Flowmeter and Transmitter.
  • Duty/standby Chemical Dosing Pumps.
  • Eyewashing station, with 3kL potable water tank and pump.
  • New pipework and supports.
  • Barrier protection (to meet DS79.3 requirements).

The upgraded Chlorine Dosing System will be housed in an insulated sea container building positioned on a gravel hardstand, and will include a solar renewable energy system to ensure the Chlorine Dosing System will be able to continue to operate in the unlikely event of a power failure.

All aspects of the upgrades to the Chlorine Dosing System at Mt Roe Dam will be completed in accordance with the Contract, Water Corporation Standards and Australian Standards.

The project is expected to reach Practical Completion by mid-October 2020.
