Environmental Management

We occupy a unique location on the Manukau Harbour, a location that includes habitats, heritage and environments that need protection. We recognise the need to manage significant impacts such as aircraft noise on the local community and environmental risks such as stormwater or groundwater contamination from airport operations.

Auckland Airport has an environmental policy in place that is supported by a comprehensive environmental management plan (EMP).  The EMP includes an assessment of environmental risk that will be reviewed on an annual basis to ensure continual improvement in environmental performance.

Environmental Risk Management

We have developed an environmental management system based on the need to manage key environmental risks such as:

Aircraft noise and its impact on local communities;

The protection of both stormwater and groundwater;

The need to avoid contamination of the ground;

Waste minimization, recovery and recycling;

Pollution prevention

The aim of stormwater and groundwater management at the airport is to prevent contaminants of any type entering the stormwater system and being discharged into our Manukau Harbour. We have a stormwater management plan to achieve this.

Stormwater consents and ponds

Stormwater management is based on catchment management including the installation of stormwater ponds.

There are six stormwater ponds on airport land. Their main role is to protect the water quality of the Manukau Harbour, by providing treatment of airport stormwater before it enters the harbour. Some ponds have important secondary purposes, including balancing peak flood flows and providing a visual and recreational feature and a wildlife habitat.

Stormwater management also includes a strong focus on good housekeeping, such as the regular cleaning of roads, cesspits and interceptors around the airport to check water quality. This prevents contaminants like dirt and rubbish being flushed into and through the stormwater system.

Spill planning and response

Stormwater and groundwater are protected by planning for and responding to spills. We discourage spills and ensure any spills are cleaned up before contaminants enter the airport drainage system. Education and training of operational and monitoring staff is a top priority. An airport specific spill management handbook raises awareness of issues and procedures for all airport workers and property tenants.

A range of purpose-built wash facilities have been developed so vehicle and aircraft wash water does not enter the stormwater system. The wash water instead enters the sanitary sewer system.

Wash facilities include public facilities for washing cars and trucks. Car washes are available at the two Shell stations on George Bolt Memorial Drive and Tom Pearce Drive.  A truckwash is available on Laurence Stevens Drive.
