On Sunday 16 May 2021, Tanker 74 participate in the Tri-County Water Supply drill in Valley Lee. Units throughout the three Counties completed several drills and discussed numerous water supply options that can be used on incidents. The apparatus was involved in a Water Supply Relay Operation and a Tanker Shuttle Operation. This was a great experience for all the Departments involved and an opportunity to learn something new. Thanks for allowing us to take part in this drill.
