This page is a pilot. We are currently working on how we present information about water quality monitoring for the Wellington region.

Sampling

From 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.

Dry weather recreational testing standards:

  • Green: <140
  • Amber alert: 140> (re-test)
  • Red alert: 280> (re-test, open signs and public warnings)

Yesterday evening the Wellington Water team
was called out to a wastewater overflow near
South Beach Access Road in Titahi Bay.

They worked fast and were able to prevent
any wastewater going into the beach, but
what they did discover was a… fatberg!
For more information on what a fatberg is, go here.

This morning we identified that the ultra-violet (UV) treatment equipment
was not running at the Porirua Wastewater Treatment Plant. It was reactivated
as soon as it was discovered; however, it had been off since 3pm yesterday.

The risk to health from this bypass is very small, as the tidal current will dilute
and disperse the un-UV-treated wastewater. We have done some shoreline
monitoring and have shared the results on our website below.

Ultra-violet (UV) light disinfection is the final stage in treating wastewater.
The treatment process removes solids most of the harmful bacteria before
it gets to the UV stage. UV disinfection destroys remaining bacteria and viruses
before it is discharged to the sea.

We are treating this extremely seriously, particularly given the lessons learnt
after the incident in January. We sincerely apologise that this has occurred and
will do everything we can to prevent it happening again.
