Report summary

The review has highlighted that the management and operation of the wastewater treatment plants, and the ability to effectively deliver public health and environmental objectives, has not been consistently achieved by Veolia.

However, the review has also highlighted improvements that Wellington Water can make as well. While Veolia is responsible for its failure to meet the expectations of Wellington Water in its delivery of operations and maintenance of the four WWTPs, the contractual environment has also played a role Veolia’s performance.

In taking all these factors in consideration, the review panel has recommended that we retain Veolia as our contractor. This is on the proviso that Veolia commits to, and delivers, on several significant improvements in its planning, delivery, and resourcing, and that we work to enhance our capability, systems, and processes to allow better management of Veolia.

Our next step is to implement the recommendations in the final report. We have developed an implementation plan, which has been endorsed by Wellington Water’s Board and we will keep you, our community, and mana whenua informed as this work progresses.

Background

The review was initiated in October following 10 warnings, infringement, and abatement notices across wastewater operations since May 2020.

It aimed to identify actions and improvements to the wastewater treatment plant operating model that will ensure all the plants are operated in a professional, proactive, modern, fully compliant, and environmentally responsible way, and meet the expectations of Wellington Water, our communities, our client councils and mana whenua.

It was led by independent reviewers Roly Frost and Raveen Jaduram alongside Wellington Water’s Chief Advisor - Service Delivery, Euan Stitt.

A Steering Group, made up of Porirua City Council’s Deputy CEO/GM Infrastructure Andrew Dalziel, Ngati Toa’s Helmut Modlik, Veolia’s Alex Lagny and Wellington Water’s Chief Executive Colin Crampton, was also established to provide input to the review process.
