T T to page 12 REGIONAL DEVELOPMENT In October 2023, Hastings District Council (HDC) completed the staged delivery of its ambitious, but critical, Drinking Water Capital Upgrade Programme that commenced in 2018. Graeme Hansen, Council’s Director of Major Capital Projects has overseen the project since its inception, and says that while HDC faced a number of challenges impacting the project; including a highly competitive construction market, inflation, Covid, and a major cyclone event, the project has been a triumph on many levels. The journey began in 2016 after Havelock North suffered a major water contamination event that resulted in wide spread sickness through campylobacter, and contributed to the deaths of four people. Hastings’ water is supplied from the giant Heretaunga Plains aquifer accessed from bores, some under artesian pressure. Until 2016, the water was taken from the ground, put into the network and consumed without any treatment. Havelock North sits just 2 kilometres south-east of Hastings City, and shares the same water source. Following the water contamination event, HDC adopted a new drinking water strategy embracing a complete change in how drinking water is accessed, processed and delivered to its urban population. That new strategy resulted in projects to develop two major water treatment plants in Hastings; one at Frimley Park, while the other, known as the Waiaroha plant, sits on Council-owned land on the corner of Southampton St East and Hastings St South. Collectively, the two plants embraced a significant share of the HDC $95 million Drinking Water Capital Upgrade programme, and formed part of HDC’s multi-barrier approach to drinking water safety, which included treatment of the source water using UV treatment, chlorination disinfection, and fluoridation. The upgrade programme also included treatment plant upgrades for eight small community water supplies, and a five-kilometre pipeline from Hastings to Havelock North supplying a new booster pump station. Graeme says when selecting sites for the new plants that collectively service Hastings’ urban population of 55,000 people, the Council looked to retain as much of the existing infrastructure as possible. · Water Treatment · Design & Build · Pump Stations · Shutdowns · Wastewater Treatment · Chemical Dosing · Mechanical Engineering · Maintenance www.maxtarr.co.nz | 0800 363 888 | enquiries@maxtarr.co.nz NEW ZEALAND'S BOLTED STEEL PANEL TANK EXPERTS Whether its potable water storage, containment for a dairy factory, effluent storage for a farm or sludge tank for a wastewater treatment plant, Reliant Solutions has the storage solution for you. + GLASS FUSED TO STEEL + EPOXY COATED STEEL + STAINLESS STEEL + LINER TANKS
