Sea Water Desalination, Richards Bay, (South Africa)

Sea Water Desalination, Richards Bay, (South Africa)

South Africa suffers from severe drought in the past 5 years, facing an acute water shortage in the South-Eastern province of KwaZulu-Natal (KZN). The Provincial Cabinet issued a drought disaster declaration in December 2014, and the Emergency Water Transfer Scheme was activated in July 2014. The South African Department of Water and Sanitation (DWS) decided to look for a solution to improve access and security of drinking water supply within the King Cetshwayo District Municipality.

  • Location: Richards Bay, KZN, South Africa
  • Project: Engineering, Procurement, Installation Supervision, Commissioning, Start-Up, Training and Remote Monitoring & Consultation Service.
  • Solution: Seawater Desalination (Reverse Osmosis)
  • Capacity: 10,000 m3/day

Challenges

MEB completed a decentralized water desalination facility in 7 months. The innovative facility enables the communities in and around Richards Bay to avoid further hardship, following a prolonged drought.

 

The plant was delivered with centralized intake, post-treatment and remote monitoring, the smart design ultimately makes the plant both more efficient and less costly in terms of infrastructure, equipment and operation and maintenance.

 

The NIROBOX based plant is successfully desalinating seawater seven days a week, twenty-four hours a day to produce 10,000m3/d of potable, high quality drinking water to serve the local community of about 150,000 households.

Solution

Based on needs for rapid delivery, fast set-up, and immediate deployment, a plant based on 10 NIROBOX containerized SW RO (Sea Water Reverse Osmosis) units was contracted in August 2016. Because the entire plant is based on ten 40-foot shipping containers, it has an extremely small footprint and was rapidly deployed.

The NIROBOX SW desalination system is a modular, pre-assembled, containerized solution that’s ideal for a compact area with minimal infrastructure. It comes ready for integration with other systems and equipment and it completely modular, allowing for staged expansion to support capacity upgrades, if desired.

A Critical Link: Water and Public Health Facilities

The deficit of water and sanitation infrastructure is a major issue that directly impacts hospitals and clinics – without enough water, disease in the population grows, because of the lack of basic water, sewage and waste disposal services. Combining a semi-arid country like South Africa with rapid urbanization and industrialization, a heavily biased population migration pattern toward the cities and peri-urban suburbs, and the eminent negative impact of climate change – make long-term planning for water security a very complex matter that needs urgent addressing
