RAND WATER ANNUAL REPORT 2023

BULK SANITATION PROJECTS (SECONDARY ACTIVITIES) Ageing Infrastructure, sewage spillages into the Vaal River, and demand that exceeds the design capacity of the wastewater treatment capacity in the Sedibeng Region have necessitated the implementation of the Sedibeng Regional Sewer Scheme Project for both Midvaal and Emfuleni Local Municipalities. The objectives of the projects include the delivery of an effective solution that will eradicate pollution in the Vaal River and its tributaries and eradication of water and sanitation service delivery challenges, inhibiting both social and economic development in the region. Thus, the project aims to optimise the sanitation infrastructure within the Sedibeng Region as it is old, resulting in high maintenance costs and performance failures, align the design capacity of all Wastewater Treatment Works to the demand, and unlock 37 000 hectares of developable land previously constrained by the lack of bulk sanitation infrastructure. The following

projects are being implemented. Table 12: Bulk Sanitation Projects Project name
