Drinking Water for Seddon Water Treatment Plant
Marlborough District Council
Safe Drinking Water
Boil water notices was part of life if you lived in Seddon, a south Marlborough town in New Zealand. The water quality there was unsatisfactory as the town sources water from the Black Birch Stream where there is a presence of algae; during heavy rain flows, the water would turn cloudy and the old water treatment system could not cope with the runoff.
Furthermore, the Kaikoura earthquake allowed previous unseen organics to enter the water source causing significant taste and odour issues. With Seddon being in the earthquake zone, the town needed a new water treatment plant that is reliable and resilient to provide clean and safe drinking water.
What We Did
The water treatment plan was a huge milestone for Seddon. For the first time in decades, they have clean and safe drinking water straight from their taps. Furthermore, an emergency water supply was factored in to cope with reduced flow, meaning the town will still have clean water should another earthquake happen.
