4. Aircraft
If WSPs at the airport and transfer points have been developed and implemented correctly,
the water provided to the aircraft should be of acceptable quality. If the available water being
provided to the aircraft does not meet the GDWQ or national requirements, then the aircraft
operator must take measures to ensure that water on board is safe. These may include, for
example, a decision not to board water at that location or to obtain water from an alternative
source, such as a contract provider.
