Special purpose districts are local governments designed to meet a specific need. They are separate governmental entities that have been created to provide specific services or address specific issues within a particular geographical area. These districts usually have their own governing bodies and are responsible for providing and managing a specific service, such as water and sewage treatment, fire protection, or school districts. They have the authority to collect taxes or fees to fund their operations and have the power to make decisions and policies related to their specific purpose.
