Is the tank half full or half empty?

Rainwater harvesting can be an effective solution
“Africa is not water scarce. The rainfall contribution is more than adequate to meet the needs of the current population several times over”
UNEP/World Agroforestry Center report Nov, 2006
– Suitable wherever it rains– Simple technology: adaptable to local context and materials– Decentralised approach and local ownership– Rainwater needs (little to) no treatment → with basic
maintenance measures: WHO standards– Environmentally sustainable

Geographic focus of the RAIN Foundation
Target countries:
– South Asia
– Sub-Saharan Africa

RAIN's approach to implementation
− Site selection: regions where RWH has greatest positive impact− Selection & training of implementing organisations− Pilot phase large-scale implementation− Identify a Rainwater Harvesting Capacity Center− Continuous learning, exchange & innovation, monitoring, evaluation,
fundraising

RAIN achievements– Since 2004 active in five countries– 1,800,000 liters of RWH capacity reaching 12,000 people– Financial commitment from important donors
RAIN strengths– Focus on implementation – Dedicated and flexible – Clear strategy, including long-term sustainability– Broad network (local partners; expertise; donors)– Systematic monitoring, evaluation and continuous learning
![Page 11: RAINWater Harvesting, Multiple Use Water & Livelihoods Is the tank half full or half empty?](https://reader035.fdocuments.in/reader035/viewer/2022070411/568148ea550346895db60734/html5/thumbnails/11.jpg)
Critical success factors for RWH
Success depends on:– Initial sites only where other water supply systems ‘fail’– Appropriate technology and low cost– Local ownership & maintenance (communal → household)– Responding to demand, marketing, capacity and ‘critical
mass’ (communities, NGO’s, government, donors and private clients; financial mechanisms)
– Systematic monitoring & performance measurement

Purposes of rainwater harvesting
Domestic use – Drinking water– Hygiene & Sanitation
Productive use– Agriculture – Livestock – Other livelihood/income-generating activities
Groundwater recharge … Integrated Water Resources Management

Types of RainWater Harvesting?
− Roof top water harvesting− Surface run-off harvesting− Sand dams
… Sub-surface dams, pond reservoirs, terracing …

RAIN: from drinking water to multiple use
Points of Discussion
– Water quantity– Water quality– Techniques used & in combination with other water supply – Financing mechanisms– Partnerships & learning
The long-term– Multiplier effect: RWH / financing mechanisms– RWH for livelihood protection & productive use
