Buller District Council

Conns Creek Upgrade to proceed for Waimangaroa Water

1st April, 2021

Waimangaroa currently has an untreated water supply sourced from Conns Creek. It is under a permanent ‘Boil Water Notice’ due to public health risk, and is also vulnerable to loss of supply, poor water quality and maintenance hazards. There are 140 connections serving a population of approximately 250 residents.

Council resolved at its meeting yesterday to proceed with the Conns Creek Upgrade project to provide a safe, reliable and adequate drinking water supply for Waimangaroa, compliant to Drinking Water Standards New Zealand.

The first stage will be the raw water system to upgrade the existing intakes, settling tanks and install 2.8km of new pipeline to connect to the town reticulation.

This first stage will be funded from the $1.45M project budget approved by Council in September 2020 and delivered under an Early Contractor Involvement (ECI) design and build appointment. Local specialists experienced in civil construction and waterworks infrastructure across difficult terrain will develop the detailed design and firm pricing.

A recommendation for the raw water system will be brought to Council for final approval as part of the normal procurement process. Additional scope of town reticulation priority renewals will also be considered in the first stage should there be sufficient budget.

The second stage which includes the Water Treatment Plant and treated water storage will proceed subject to receiving $1.23M of external funding through the Ministry of Health CAP subsidy and any additional tranches of Three Waters Reform funding.

Affordability remains the biggest challenge for rural water supplies such as Waimangaroa with a small ratepayer base. Council acknowledges that the competing tensions of meeting compliance and keeping rates low is difficult without external funding.

Mayor Jamie Cleine says “A compliant and reliable water system for Waimangaroa has to be achieved in an affordable way for residents. The decision to proceed with the project in a staged delivery maximises the potential for external funding to be secured, and hence assists the affordability.”

“The community have been very consistent in their desire to utilise Conns Creek as the raw water source and I think the first stage of renewing the intakes and trunk main will serve the community well whilst work continues to procure and fund the other stages”
