What are the primary requirements for water quality aboard aircrafts?

EPA published the Aircraft Drinking Water Rule in 2009 to facilitate safe drinking water for passengers and crew. 

The major components of the rule are:

  • Developing and implementing operations and maintenance plans and coliform sampling plans.
  • Routine disinfection and flushing based on manufacturer recommendations and routine monitoring.
  • Self-inspection of the aircraft water system every five years.
  • Corrective action in response to sample results or other situations that may be a public health risk.
  • Public notification in response to situations that may be a public health risk.
  • Periodic compliance audits by EPA.
