Overview

IChemE Wellington regional group invites members to a tour of Te Mārua Water Treatment Plant.

The Te Mārua Water Treatment Plant is a critical infrastructure asset to Wellington region. It currently provides up to 80 million litres of drinking water per day (MLD), at an average of 60 MLD - approximately 45% of the Wellington region’s 135 MLD drinking water demand. The plant is designed for a maximum plant flow of 140 MLD, however is currently limited to 80MLD under specific raw (untreated) water conditions. 

Recent population growth forecasts and water consumption data indicate that over the next two years the risk of water supply restrictions to customers could increase significantly. Upgrades will allow the plant to provide a larger amount of water to meet the needs of the region, while also improving the plant’s ability to remove algae, sediment, and odour from the water.

Time:

• 16:30 - 17:30 Greig Wilson, Senior Project Lead at Beca, will guide around the site and discuss the capacity upgrade.
