Kusini Water

Pure water every community deserves.
2019 SEED South Africa Award Water, Sanitation & Health (WASH) Johannesburg, South Africa

Kusini water is a social enterprise that works with local companies to get off the municipal water grid. Kusini water uses locally sourced macadamia nut shells that would otherwise be waste. Kusini filters are low pressure and low energy, meaning that they use solar power at large scale and zero grid electricity.

Kusini uses locally sourced material. The organisation is innovative not only in the way it purifies water, but also through its decentralising treatment that ensures a more local distribution of water. Kusini systems produce more water while using less energy than comparable practices.

Eco-Inclusive Impacts

Kusini offers improved overall quality of drinking water for the community using solar and gravity feed, the main target is to reduce greenhouse gases and water pollution caused by coal-fired stations.

  • Improving overall quality of drinking water for the community: thereby reducing child mortality (studies show that waterborne diseases are the 3rd biggest cause of child mortality for the developing world)
  • Shortening the distance to the nearest tap (safe drinking water source)
  • Electricity constitutes up to 60% of operating costs for water production, by using solar and gravity feed. The main target is to reduce greenhouse gases and water pollution caused by coal-fired stations. Kusini is able to measure the amount of water produced on renewable energy.
  • Kusini Water has 7 team members and has generated revenue of over R500,000 in the last year.
  • Job creation and growth: Kusini aims to create both farming and filter production jobs through the business.
