Wastewater Treatment

Water and wastewater treatment is critical to our standards in maintaining sustainable continuity and green compliance in constrained environments where we need to treat, and stabilize effluent quality and safety.
Clean water treatment process

Thanks to its technological expertise and local presence, Veolia supports municipalities, industries and mining operators at every stage of the water cycle: abstraction, treatment, distribution, collection and purification. 

Our solutions integrate the most advanced processes to reduce energy consumption, maximise reuse and limit discharges into the environment.

 

Comprehensive Solutions
Across the Entire Water Cycle

 

Veolia has supplied water and wastewater treatment solutions for municipalities across South Africa for over 20 years. 

The company develops customised drinking water and wastewater treatment plants designed to effectively handle the growing volumes linked to urbanisation. These facilities ensure water quality in line with international standards while contributing to public health and local development.

Through its operations across the country, Veolia helps local authorities strengthen access to essential services, secure water supply and protect fragile ecosystems. The Group also provides technical support and long-term operation services to guarantee sustainable performance of treatment infrastructures.
