Convert water tower node to area / Maproulette Challenge Feedback

It wouldn’t be fair to assign any blame to the actual mapper here. They’re trying to improve the data in OSM, and the Maproulette challenge - which is listed as “Easy” - simply states:

Convert man_made=water_tower nodes to areas:

• Use aerial imagery to draw area
• Be sure to copy every node tags to the area (the easiest way is to merge the node into the new area)
• If possible, merge the node with the existing area

Even if the tower is clearly visible in aerial imagery it can be difficult to map it.
Have a look at this one, that I do know very well:

mapped as area, not through this challenge.
