Our Team

Gamtoos Water’s staff complement comprises approximately 130 personnel. Ninety of these operate in and around Patensie, focusing on the management of water from Kouga Dam to water users. The remainder are situated throughout the Eastern Cape and are involved in the management of the Expanded Public Works Programme (EPWP) projects entrusted to the Board by the Department of Environmental Affairs.

Nurturing skills development is critical in ensuring the sustainability and effectiveness of the organisation. Our policy is to identify talent and to promote from within.
