What's stormwater?

Stormwater is rain which has run off hard surfaces such as roofs, roads and carparks. Stormwater is not treated and the water ends up in streams and harbours. Stormwater and wastewater use two different pipe systems - wastewater pipes take the wastewater to a treatment plant while stormwater pipes take stormwater to the nearest waterway.   Read more

Why is my water out?

Water supply interruptions are either planned or unplanned. Planned outages usually happen when we’re replacing a section of pipe, rather than fixing a burst or leak. You should have received a letter explaining this would happen and when. If you didn’t, chances are it’s an unplanned outage. Unplanned outages usually result from water main bursts.  

When there is a significant water burst the auto shut-off valve (ASV) is triggered.   Read more

Bursts and overflows

We are providing regional (all city/district) figures for service requests (all waters); bursts where drinking water supply is interrupted; leaks where there is no loss of supply; and overflows where wastewater has ended up outside of the system (like in gully traps, driveways, roads, gardens and homes).   Read more

Stormwater or wastewater?

Stormwater is rainwater that flows across roofs, roads and driveways into the stormwater system. Stormwater is not treated to remove any pollutants. Wastewater is the dirty water from houses and businesses that is flushed or sent into the wastewater system. Wastewater ends up at a wastewater treatment plant where the wastewater is treated, solids removed and the liquid or effluent is discharged to the sea.   Read more

Titahi Bay water quality 2021

This page is a pilot. We are currently working on how we present information about water quality monitoring for the Wellington region. SamplingFrom the 31 March 2021, this schedule will be fortnightly and only at Toms Beach Road. Any significant change in results will trigger a detailed investigation. The regular sampling programme may be supplemented by one-off sampling in accordance with resource consent conditions, should we experience an incident with the network or the Porirua Wastewater Treatment Plant.   Read more

How long will my water be off for?

Across the Wellington region, there are around 30-40 instances per week when the water needs to shut off.  Most water main bursts are fixed within a couple of hours. However, a range of factors can affect how long it takes:

Where the burst is. A burst in the middle of a busy road means traffic management has to be organised. In some cases, eg during rush hour, repairs may be delayed until traffic volumes reduce.   Read more

Why do I need to stay out of flood water?

It's best to stay well clear of any floodwater. There's a good chance that the floodwater is not clean as it may be contaminated with wastewater or surface pollution. There may also be unseen hazards lurking under the floodwater such as open manholes (where the manhole cover has been lifted away), ditches or obstructions such as trees or debris. If you come into contact with floodwater, please wash your hands carefully as soon as you can.   Read more
