South Africa has begun the process of establishing a new utility to help it entice private investment in infrastructure needed to head off potentially crippling water shortages. The Department of Water and Sanitation plans to submit a bill to the cabinet by the end of April that sets out proposals for the creation of the National Water Resources Agency, according to Sean Phillips, its director general. It will be created by combining the department’s Water Trading Entity and the Trans-Caledon Tunnel Authority, or TCTA, and could be operational next year.
