Wellington Water is working to identify the cause of a brief spike in the fluoride levels at Waterloo Treatment Plant.

Recent data from Wellington Water shows leaks in the Wellington metropolitan region (Wellington City, Porirua, Lower Hutt and Upper Hutt) have hit a 4-year low this month, dropping from 1,720 leaks on January 1, 2024 to just under 400 leaks on January 6, 2025 on the public network – a reduction of over 75%.
Council’s increased investment in leaks enabled Wellington Water to ramp up leak repairs, with all councils leaks at or nearing a sustainable level.

High water use in Martinborough has increased the risk of the town triggering Water Restriction Level 2 in the coming weeks.

A key upgrade to the region’s critical water infrastructure has been delivered ahead of schedule and is already having a positive effect on the region’s water supply.

“The Te Mārua Water Treatment Plant is a critical piece of the region’s water supply as it provides around 45% of the region’s drinking water,” says Greater Wellington councillor and Te Awa Kairangi Subcommitee chair Ros Connelly, whose council fund and own the region’s water treatment plants.

“The first of two stages of recent upgrades completed by Wellington Water mean the plant is now able to treat and supply an additional 20 million litres of drinking water per day.

“This milestone is great news and an important step towards increasing Wellington’s water supply resilience, especially as the region enters summer, when we experience tighter water restrictions.”

Wellington Water advises that the boil water notice has been lifted for residents in 81 - 125 (odd numbered) and 90 - 118 (even numbered) Montgomery Ave, all of Cathie Place, and all of Stockden Place in Karori.

Wellington Water advises that residents in 81 - 125 (odd numbered) and 90 - 118 (even numbered) Montgomery Ave, all of Cathie Place, and all of Stockden Place in Karori must boil their drinking water before being used for drinking, food preparation or brushing their teeth.

Today’s karakia ceremony for the Kaitoke Pipe Bridge marks the project’s completion and the official handover of the bridge to Greater Wellington Regional Council and the public.

Wellington Water’s latest modelling shows that work to reduce water loss on the public network has had a significant impact on the risk of tighter water restrictions this year, but continued investment is needed to hold the risk at bay.

Current modelling shows the risk of Water Restriction Level 2 has gone from 100% last summer to 40% this summer, Level 3 from 70% to 14%, and Level 4 from 33% to 4%.
