West coast lagoons


Improving the water quality

Auckland Council is working with the community to improve the water quality at Karekare, Piha, North Piha and Te Henga lagoons.

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 septic tanks, long drops and hi-tech systems. These maintenance issues allow untreated wastewater from showers, baths, washing machines and toilets to get into waterways. This can happen even when the systems are a long way from streams.

Our water quality project will address the issue through:

  • an awareness programme focusing on better management of septic systems
  • subsidies 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 also request a free on-site wastewater system inspection. For more information, see the EcoMatters Environment Trust website.
