Case study – sustainable water supply

The Wakel River Basin Project, India
Key details	Located in Rajasthan, India, an arid region with water scarcity. Aims to improve water supply through sustainable methods including: taankas (underground storage systems to collect rainwater and prevent evaporation), johed (small earth dams to capture rainwater and recharge groundwater) and pats (irrigation channels to distribute water efficiently).
Benefits	Increased water availability for drinking and farming. Improved crop yields and reduced poverty. Low-cost and sustainable, using local materials.
Costs	Limited to small-scale use; cannot service large populations. Success depends on community participation/maintenance
