Carex of Sweden plans to install their TreeWell biological wastewater system with integrated off-grid water purifying technology. They are aiming to build a showcase of how innovative Swedish technology can supply an off-grid circular water system, saving energy and water. Wastewater from toilets will be purified through several steps where the last step provides Safe Drinking Water according to WHO standard.
This showcase is already built in Kungsäter, Sweden. In this case, Carex of Sweden will deliver solutions that are solving the real challenges that exist in the rural areas of Rwanda. Technical sampling and methods of survey of both technical as well as socio-economic aspects, are being discussed.
