Regulatory context

Partial review. This is not an exhaustive review of applicable law.

South Africa: National Water Act, uses and authorizations

Partial documentary review; human legal review pending. Section 21 water uses include waste-containing discharges and other disposal that may affect water resources. Section 22 provides different routes, including a licence, general authorization and other lawful cases. A missing individual licence in an inventory does not establish unlawful use.

Determine the section 21 use, authorization route, conditions and competent authority.
Do not confuse user registration with a licence or assign one route to discharge, irrigation and land disposal.
