Early Contractor nvolvement Upgrade of Four Water Tretament Plants in Southland
17/09/2014
The existing Water Treatment Plants (WTPs) in the Southland District Council (SDC) communities of Te Anau, Mossburn, Otautau, and Winton required improvements to comply with the Drinking-water Standards for New Zealand 2005 (Revised 2008) (DWSNZ). All existing supplies were similar, consisting of shallow bore water sources, primary pumping, and chlorine gas disinfection, followed by secondary pumping into the reticulation where needed.
