Updates to the wastewater network in the Upper Clutha as part of this project include: Construction of a new wastewater pump station (WWPS) at Domain Road in Hāwea, and a 12.5km, 315mm-diameter pipeline from Domain Road to existing infrastructure at the Albert Town WWPS. Upgrades to the existing Riverbank Road WWPS, and construction of a 7.4km 630mm- diameter pipeline rising main in the road reserve using easements from Riverbank Road WWPS to the Project Pure wastewater treatment plant (WWTP). Upgrades to the Project Pure WWTP inlet. Decommission the Hāwea WWTP - issues with nitrate into the field Simon says there have been no major challenges encountered to date, but crews have had to contend with working close to the road corridor and at times, in very narrow areas, all while juggling traffic management and trying to minimise how this affects road users. The Hāwea WWTP will be decommissioned over 12-18 months once the new pump stations and pipelines are operating.
