Although technology plays a vital role in getting clean water and toilets to people, the problem is not one that can be fixed with a ‘silver bullet’ technology. Charitable distribution of inventions – such as filters, pumps, purifiers, water condensation units, rolling water butts or similar – has been tried many times in the past, but only ever achieves limited short-term impacts. Instead, the crisis is largely a management problem – one where governments and the local private sector don't have the finances, skills, coordination and dedicated institutions to provide water and sanitation services to citizens. We want to see the eventual establishment of permanent services like these through governments and service providers. This is where real innovations in approach need to happen. In our community work, we use reliable, simple technologies that are sourced locally, so that people and their governments are better able to maintain them sustainably in the future.
