The town where I live has a rule, which you must meet when putting a swimming pool or pond in your yard. You must have a fence installed around the area for protection. I suppose the chance of a small child falling in is the reason for the rule. The outdoor garden fountains are very lovely and give us a feeling of tranquility that only a work of art like these can do. I would love to have one, but I'm sure the city would give me fits with all the different permits I would have to meet and buy.
