Rainwater harvesting offers a high-potential solution for safe (drinking) water, thereby empowering people to improve their livelihoods due to more water security and new choices. Being a decentralised and low-cost technology, rainwater harvesting enables people at household and community level to manage their own water. Furthermore, RWH provides “water without walking”: the water being collected where it is used, at households or community buildings. This saves time and energy which can be spent on social and economic activities that can contribute significantly to poverty alleviation and sustainable development.
Rainwater harvesting has proven to be an attractive alternative water source in areas where other means of water supply have no or very little potential. Of increasing relevance is the solution offered by (rain)water harvesting in protecting vulnerable communities from the expected negative effects of climate change.
