Overview

Whakatane District Council wishes to develop a new water source for Edgecumbe and Te Teko Water Supplies called the Otumahi (Paul Road) Water Supply that meets the Drinking Water Standards for New Zealand (DWSNZ). Currently, these townships are supplied by Braemar, Johnson Road and Tahuna Road water sources which do not meet DWSNZ due to either elevated levels of arsenic and antimony and/or because they are not a secure water source. The aim of the whole project is to isolate Edgecumbe Township and Te Teko Township and some of the neighbouring areas from Johnson Road and Braemar Sources and to supply these areas from Paul Road and Tahuna Road Sources.

A new bore site will be developed (with associated treatment plant and pump station) at a site on Paul Road and the existing Treatment Plant at Tahuna Road will be upgraded. The Paul Road site has an existing bore, 169 m in depth, with suitable water characteristics to meet DWSNZ. The water abstracted from this bore will be treated through chlorination and pH adjustment before being pumped via an 8.0 km pipeline to Edgecumbe. The treatment plant at Tahuna road Source, which is currently being treated with chlorination only will be upgraded to meet the Drinking Water Standards for New Zealand (DWSNZ).

The construction works consist of three distinct packages described below. This contract is for the construction of the Bore Site Development.

• Contract 17-011: Otumahi (Paul Road) Water Supply: Delivery Pipeline
• Contract 2 17-016: Otumahi (Paul Road) Water Supply: Bore Site Development
• Contract 3 (TBC): Upgrading of the Tahuna Road existing treatment plant
