Alan Fortenberry is CEO of Beaver Water District. I've had the opportunity to photograph many projects for BWD over the years. This shoot was for a national engineering magazine. I always walk away from BWD more educated about the work that goes into making the water for NWA clean and safe to drink. Just so happens that this day I was able to view the bottom of one of the Sedimentation Basins (bottom image). You can see one full in the background of one of Alan's photos, the purpose of this is rid the water of sediment and done so with he 'paddles' or boards that slowly work across the bottom, pulling the sediment towards the middle of the long pool, then that is transported out to another container. This is just one of the several stages to make the water clean. Normally it's hard to see the boards, this particular day they were cleaning out the bottom and examining for any needed repairs.
