VAAL TRIANGLE - Vaal Triangle and other SA consumers could face a water tariff hike of up to 16% in the next financial year. Water and Sanitation spokesperson, Sputnik Ratau, says the department invests more than R50 billion per year in water infrastructure and treatment. Ratau adds that in setting the tariffs, they take the state of the economy and affordability into account. But they have to be able to do the important work in their mandate. Chief Water Resource Planner in the department, Tendani Nditwani, emphasised the need for properly managing water and sanitation services while ensuring financial sustainability. Nditwani said this can be achieved by implementation of accurate billing and effective revenue management systems in all entities, including for the agricultural, industrial, commercial and domestic users. Acting Deputy Director-General for Infrastructure Development in the department, Leonardo Manus, said the department is working behind the scenes to ensure that water supply is not disrupted.
