Duvauchelle Water Supply Treatment Plant

⁠⁠⁠Overview

Christchurch City Council is inviting Tenderers to submit tenders for the upgrade of the Kaitouna Duvauchelle Water Supply Treatment Plant.

About

The existing Duvauchelle Water Treatment Plant (WTP) utilises conventional media and cartridge filtration technology and does not consistently comply with the Drinking Water Standards for New Zealand. During high turbidity events, water must be brought by tanker from elsewhere to meet demand, at a significant cost.

Purpose

The purpose of the project is to upgrade the existing water supply treatment plant to ensure that Council provides a facility that meets the following outcomes.

Objectives

• Produces drinking water in accordance with the New Zealand Drinking Water Regulatory Framework
• Utilises membrane filtration to provide a minimum 4 log protozoa credit
• Has low total lifecycle costs, including by minimising energy use and chemical use
• Provides fully automated plant operation, with a high level of reliability, to minimise operational interventions and maintenance requirements and associated costs
• Has conforming electrical, instrument and controls system design and operation, including SCADA interface and telemetry system

Scope

The scope includes:

• Construction of the new treatment plant on the site of the existing treatment plant
• Maintaining the site as an operational water treatment plant in continuous service throughout the Contract
