New Appointments and Variations

New Appointments and Variations (NAVs or new appointees) allow companies to offer water, sewerage, or water and sewerage services to a specific geographic area instead of the existing incumbent company. As a result, developers and large business customers can choose their supplier for these services. 

New appointees have the same duties and responsibilities that apply to all existing appointees.
