 MCAS Iwakuni Utility Marines gathered at Penny Lake for a water purification exercise. You may be surprised to learn that purifying water is a job that can't be done without the expertise of some other Marines. Well, as any Marine in the utilities between such as us, you have electrical side and water side. And see, we're working hand in hand. We have our generators powering up their water purification systems. If they don't have the generators to provide power, they can't provide clean water. The electrical repair and water purification Marines work together throughout the week to convert lake water into clean water as part of an exercise. We bring our tactical water purification system, a lightweight purification system, to be able to provide water for the Marines. And generators, we have the generators out here so we can provide clean water, light and heat in the tents, as well as our AC units out here.
