In January 2026, the Defence Laboratory Jodhpur (DLJ) under the Defence Research and Development Organisation (DRDO), developed a portable water purification system ‘SeaWater Desalination System (SWaDeS)’, available in manual-operated and engine-driven variants, to supply safe drinking water to soldiers deployed in remote, coastal, and water-scarce regions.
- What? Portable Sea Water Desalination System (SWaDeS) developed
- Developer: Defence Laboratory Jodhpur, DRDO
- Purpose: Provide safe drinking water to soldiers in remote areas
- Variants: Manual (10–12 personnel), Engine-operated (20–25 personnel)
- Special Capability: CBRN water purification module
- Testing: Successfully completed Acceptance Test Procedure (ATP)
About Sea Water Desalination System (SWaDeS):
Variants: The engine-operated variant can desalinate seawater with Total Dissolved Solids(TDS) up to ~35,000 milligrams per litre (mg/L) to below 500 mg/L for 20–25 soldiers, while the manual unit is portable for 10–12 personnel.
Deployment: Engine-operated system sets up within 2–3 minutes and manual units support remote or power-scarce areas.
Testing: Both variants have passed Acceptance Test Procedures (ATPs) validating field reliability.
Applications: Suitable for naval operations, coastal installations, inland saline lakes (e.g., Pangong Tso), and long-range patrols.
CBRN Water Safety: The system features a Chemical, Biological, Radiological, and Nuclear (CBRN) water purification module, ensuring safe drinking water even in contaminated and high-risk environments.
