Overview

City West Water Corporation (integrated Western Water) has applied for a development licence permission to upgrade their sewage treatment plant (STP) in Haywood Drive, Gisborne. The upgrade to the plant is needed to increase capacity to manage demand for sewage and wastewater treatment until 2035.

The upgrade will increase the plant’s capacity, improve the quality of recycled water produced, reduce energy consumption and reduce impacts on Jacksons creek.

What does the application propose?

Western Region Water Corporation is proposing to upgrade the Gisborne Recycled Water Plant situated in Haywood Drive, Gisborne, to increase capacity to service the growing population, improve treated water quality and reduce environmental impacts.

The proposal is for the installation of new technology and to increase the plant capacity to meet a service demand from 14,000 to 29,000 persons. The current Licence discharge limit is proposed to increase from 2.4ML/day to 3.5ML/day. This stage 1 upgrade would also reduce plant energy consumption and improve the quality of recycled water available from the plant. Further, on 1 July 2021, Western Water and City West Water will integrate to form a new water corporation – Greater Western Water.

Updates

Development licence issued

On 15 September 2021, EPA has issued a Development Licence to City West Water for the Concept Design (Stage 1) upgrade to the sewage treatment plant in Haywood Drive, Gisborne Victoria, subject to conditions. The upgrade to the plant will increase capacity to manage demand for sewage and wastewater treatment until 2035.

The upgraded plant will be subject to conditions that require approval of plans and specifications with new technology that meets best practice. All final plans including for human health and environment management are required to be approved prior to commencement of construction.

City West Water must notify EPA when they intend to start and finish the construction associated with the development activity and must not commission or operate components of the development activity without approval of EPA. The Development Licence will not take effect until any permit that is required under the Planning and Environment Act 1987 has been issued by the Responsible Planning Authority.
