Potable water supply for Muchea Employment Node and Riverside Residential Estate
Arris and GromEng have partnered to project manage the design and construction of a new water treatment plant and water supply network in Muchea, Western Australia. The treatment plant will provide potable water to the new Muchea Employment Node (MEN) and a rural residential Estate at Riverside.
High quality potable water treatment plant design, management, and construction
As part of delivery for this project, Arris completed a Drinking Water Source Protection Plan for approval by the Department of Water and Environmental Regulation. As part of the DWSP Plan, Arris:
- Defined the groundwater influence zone for the Leederville water supply bore;
- Assessed the risks to the groundwater supply from neighbouring land use activities;
- Analysed water quality to determine treatment methods;
- Developed a groundwater monitoring program to manage and protect water quality; and
- Identified required water supply protection zones.
Arris and GromENG have managed and delivered:
- All contractors and subcontractors including quoting;
- Site preparation works including construction pads, access tracks and security fencing;
- Construction of treated water storage tanks;
- Construction of treatment plant shed including approvals;
- Pipeline delivery route;
- Bore construction, pump testing and approvals; and
- Infrastructure inspection and handovers.
The treatment regime designed includes the use of chlorine to oxidise iron and manganese, deep-bed sand filtration, green sands for further polishing to remove any remaining iron and manganese, sodium hypochlorite to pH trim, and chlorine and UV disinfection.
