Prolonged droughts and water scarcity are becoming increasingly common in many parts of the world. This severely affects drinking water availability, irrigation for agriculture, and overall development in drought-prone regions. In such a context, adopting affordable technologies like screw pumps can help improve water access and sustainability.
Screw pumps are positive displacement rotary pumps suitable for reliably lifting large volumes of water from both underground and surface sources. They can efficiently pump viscous fluids containing suspended grit and solids without clogging, making them ideal for use in remote rural areas.
Benefits of Screw Pumps for Water Access in Drought Regions:
- Can pump from depths of 150 meters or more, helping access groundwater reserves.
- Allow high discharge rates over 2500 cubic meters per hour, ensuring sufficient water volume.
- Operate efficiently even with high sand content, minimizing wear.
- Require lower maintenance without frequent breakdowns.
- Are affordable compared to other pump types, reducing infrastructure costs.
- Can be solar-powered or hybrid-powered for sustainable operation.
By installing a network of screw pumps and pipelines, water can be supplied for drinking, domestic use, livestock, and irrigation in villages and regions affected by severe droughts. With customized engineering solutions, renewable energy integration, and community participation, screw pumps present a practical technology to build drought resilience and ensure water security.
