Belle Isle is a lakefront city in southeast Orange County, built around Lake Conway, one of Greater Orlando's largest lakes, just northwest of the airport. Household water here is almost all municipal, so Belle Isle is not a well-water town in the usual sense.
Where the wells matter is irrigation. The lakefront lawns and landscaping that run down to Lake Conway and Little Lake Conway are very often kept green by a private irrigation well, separate from the household supply, drawing the Floridan Aquifer 100 to 400 feet down. That water runs through Central Florida limestone, so hardness and mineral scale build up inside pumps, tanks, and check valves, and a system working long dry-season cycles wears faster than owners expect.
