Wellington Water crews continue to respond to the heavy rain event and network impacts

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 access limits and road closures. 

UPDATE 3.30, 20 April 

Porirua

• The stormwater intake near Rangituhi Park is blocked, causing surface level flooding on Raiha Street. Necessary remedial work will be undertaken to clear the intake as soon as possible.

• Surface level flooding has been identified around Porirua City Centre and on Onepoto Road.

• Stormwater intake assessments and remedial works in the Plimmerton area have been completed.

Hutt Valley
