I've never seen that. It seems like it would be an eyesore. Must be for the plants...which makes no esthetic sense.
Maybe to water their plants? Or to keep them cool (if frozen bottles). Some nurseries recommend stuff like this in really hot weather.
Maybe they're trying to get rid of crows by breeding mosquitos with the west nile virus...
