Design and construction of a new water treatment plant on a greenfield site. The project was designed to resolve the increasing water supply demand in Te Awamutu and the Waipa district and to future proof water supply against the projected growth in the area.

The plant can produce a flow of 12,000m3/day net treated water, readily expandable up to 16,000m3/day.

The project included:

• A water treatment building to house membranes, UV, chlorine gas, peroxide, chemical dosing system, electrical & control room, operational offices, kitchen, shower, and bathroom facilities.
• A treatment process to comply with the treated water quality requirements inclusive of all chemical dosing, pre-treatment, backwash, instrumentation, services, and compressed air.
• Above and below ground civil works, landscaping, planting, roading and water networks.
• Reservoir and storage Tanks – 1.5ML treated water storage tank and a 275m³ flocculation tank.
• Two waste sludge ponds
• Inface connections with the existing water treatment plant, potable water network, and utility services.
