Fonterra Reporoa Water Use and Wastewater Treatment Strategy

Fonterra Reporoa

Water Use and Wastewater Treatment Strategy



Water Demand Reduced by 1,000 m³/d at Peak

Problem

As part of a nationwide strategy, Fonterra were looking at ways to reduce their water usage over a number of key sites.

Solution

DETA assisted Fonterra to identify a shortlist of water minimisation and reuse opportunities at the Reporoa site, based on their potential to reduce wastewater volumes.

Outcome

The shortlisted projects were expected to reduce the water demand at peak by roughly 1,000 m³/d and included opportunities to recover, treat and reuse washwater, CIP and tanker rinse water, as well as projects to eliminate once-through water cooling systems. DETA then carried out a high level feasibility review of each shortlisted project to assess its likely costs, benefits and other implications.
