Siphon‑Powered Desalination

September 30, 2025 2 min read

Why in news?

Researchers at the Indian Institute of Science (IISc) announced a low‑cost desalination technique that uses a fabric‑lined siphon to turn seawater into drinking water. The innovation attracted attention for its potential to provide safe water in coastal areas without the high energy demands of conventional desalination plants.

How does the system work?

Advantages over conventional methods

Limitations and future prospects

While promising, the system has yet to be tested on a large scale. Long‑term durability of the fabric and the system’s ability to handle fluctuating sea conditions remain uncertain. Scaling up will require engineering robust modular units and ensuring that condensed water meets drinking‑water standards. If these challenges are addressed, siphon‑powered desalination could complement other sustainable water solutions.
