Healthy Waters

West and Little Oneroa lagoons


Improving water quality

Auckland Council is working with the community to improve the water quality at Karekare, Piha, North Piha and Bethalls (Te Henga) lagoons on the west coast of Auckland and on Little Oneroa, Waiheke Island.

These lagoons are currently not safe for swimming due to faecal contamination from humans, and from animals like cows, ducks and dogs.

The source of the human contamination is poorly maintained on-site waste water treatment and disposal systems (septic tanks) and long drops.

Our water quality project will address the issue through:

  • an awareness programme focusing on better management of septic systems
  • subsidies, voluntary targeted rate schemes, and reduced consent fees for people upgrading their septic systems
  • better follow-up of known septic system issues
  • better management of council-owned wastewater systems in the area.

For information on how you can manage your wastewater effectively, see septic tanks, or download our Love our lagoons brochure (PDF 660KB).

Residents in the catchment areas can request a free on-site wastewater system inspection. For more information, see the EcoMatters website and the Waiheke Resources Trust website.

 


Voluntary targeted rate - pilot scheme

Residents within the targeted catchment areas can apply for a voluntary targeted rate of between $2,000 and $35,000.

For more information, see Onsite wastewater treatment system.



Consent fee subsidy

Residents undertaking a septic tank upgrade in the targeted catchment areas will be eligible for a consent fee subsidy. The consent application must meet the compliance requirements.

West coast lagoon septic tank upgrade

In 2015 and 2016 the Waitakere Ranges Local Board offered a $5000 subsidy to people living in the west coast lagoon catchment areas looking to upgrade their septic tanks to more modern systems.

Applications for 2016 are now closed. For more information on the subsidy, see West coast lagoons septic tank upgrade subsidy.
