Isa Town
In 1958, the municipality started water purification projects. In 1960, Bahrain comprised four municipalities: Manama, Hidd, Al Muharraq, and Riffa. Over the next 30 years, the four municipalities were divided into 12 municipalities as settlements such as Hamad Town and Isa Town grew. These municipalities were administered from Manama under a central municipal council whose members are appointed by the king.
