Cambi signs contract for THP at Rosedale wastewater treatment plant in Auckland, New Zealand

29 Apr 2026 06:58 CEST

Cambi has entered into a contract with Watercare Services Limited to supply two
thermal hydrolysis process (THP) systems for the Rosedale wastewater treatment
plant in Auckland, New Zealand.

The contract begins with an engineering phase. Manufacturing is expected to
commence following a later notice to proceed and no earlier than 12 months from
now.

Thermal hydrolysis will increase digestion capacity at Rosedale without the need
for new digesters, support higher biogas production, improve dewatering, reduce
biosolids volumes for disposal, and reduce carbon footprint and waste while
lowering asset life-cycle costs.

Per Lillebø, CEO of Cambi, remarked:

"Rosedale is a strategically important project in a growing market and marks an
important contract for Cambi. Watercare, New Zealand's largest water utility, is
investing in long-term treatment capacity, improved performance, and reduced
emissions at a major wastewater treatment plant in Auckland. Cambi appreciates
the opportunity to support that programme with thermal hydrolysis technology
tailored to the site's requirements."

Watercare provides water and wastewater services to 1.7 million people in
Auckland and is upgrading the Rosedale plant as part of a broader investment
programme to support growth, improve treatment performance, and reduce
emissions. Rosedale is Watercare's second-largest wastewater treatment plant,
and the wider upgrade programme will increase wastewater flows reaching the
site.

The value of the engineering phase is equivalent to a small contract for Cambi,
while the total project value is equivalent to a large contract.

The project's current timeline has equipment delivery scheduled for 2028, with
operations starting in 2030.
