The airport takes steps to minimise the impact of its activities
on groundwater quality and quantity.
Minimising the Impact on Groundwater
Christchurch International Airport lies over an alluvial
fan which is part of the recharge zone for supplying
the city's drinking water. The protection
of groundwater is of major significance as a resource to
be sustainably used and protected. Groundwater provides
the airport's water supply requirements, including the public
drinking water supply and an energy source for air conditioning of
All stormwater at the airport ultimately discharges to ground.
These discharges are regulated under the RMA by Environment
Canterbury through the issuing of resource consents. The consents
set out specific requirements that can be undertaken in a
stormwater catchment and the stormwater systems.
- Implementation of an Environmental Compliance and Monitoring
- Stormwater maintenance and monitoring requirements, and
programs linked to resource consent requirements
- Labelling of stormwater inlets on operators' sites and public
carparks as "rainwater only"
- Monitoring of drinking water wells
- Environmental awareness training
