The Te Marua water treatment plant requires an upgrade to increase capacity to 140 ML/d, improve redundancy and resilience, and continue to meet the requirements of the Drinking-Water Standards for New Zealand 2005 (Revised 2018) (DWSNZ). This will be achieved by the installation of a new Dissolved Air Flotation (DAF) system and increasing the capacity of the existing chemical dosing and solids-handling systems.

This contract is for the design and supply of a new Dissolved Air Flotation (DAF) plant. This includes the design (of specified items), supply, manufacture, acceptance testing (including commissioning and performance testing), and defects liability of the DAF plant and ancillaries. The Respondent shall allow for coordination and cooperation with Wellington Water’s Design Consultant who is responsible for the balance of design.

The DAF shall be delivered to the Te Marua WTP site for installation by the Site Installation Contractor. The installation of the DAF will be carried out by the lead Installation Contractor under separate contract.
