Major weather event - Heavy rainfall for the wider Wellington region until tomorrow night.

Wellington Water crews are continuing to respond to a band of heavy rain causing surface flooding and network impacts across the Wellington and South Wairarapa regions today.

With bad weather expected for the wider Wellington region from this afternoon until tomorrow night, crews are proactively checking hotspots and vulnerable sites, and clearing out stormwater intakes as it is safe to do so.

Crews are working as quickly as they can, but we are asking residents to be patient with us as response times in some locations are impacted by road closures. 

Projects

Every year we carry out over 200 different projects in our four cities. These projects range from renewing a stormwater pipe in a single street to building a new reservoir. 

 

We are working hard to meet the region's growing water needs

Now that’s what we call a deep clean!

Constructed over twenty years ago to address stormwater flooding in the CBD, the Harris Street syphon sits 16 metres under ground level. It’s meant to drain stormwater from around Willis and Victoria Streets and discharge it, using its own momentum, at Frank Kitts Park.
