Location: tentative, at best
Mosquitoes are controllable with screens / filters and by lengthening and putting a few angles in the pipe leading into the cistern - they are not masters of mazes. I do agree that mosquitoes are a problem to be reckoned with; although I'm more concerned about my dogs getting heartworms than me getting West Nile Virus or Dengue Fever.

This also helps prevent the other unwanted entity - light - from entering the cistern directly. With light, you get algae. Cisterns must be opaque, and I know of a few brands whose lighter colors just don't get the job done. In hotter regions, it's also not a bad idea to shade the structure with a vine trellis or a "living wall." This not only reduces the amount of light falling on the cistern; it also reduces the temperature of the water inside. You don't really want to be irrigating plants with 110 degree water - a drawback to above-ground storage tanks in the Southwest. Of course, it helps if you can put the storage tank on the north side of a house, but there are many factors in locating the cistern that may outweigh that. When I get around to installing mine, it's going at the SW corner of my house, so I can sit on my back porch without constantly being reminded that my next-door neighbors have a 2-story house only 15 feet from my wall. It'll make a nice visual and sound screen, and keep the late afternoon sun off the south and west corner of the house. That also happens to be where the irrigation valves for the back yard are located, so it makes integrating the systems easier.
