What happened: NEERI-ZAR purifiers delivered to Assam flood districts
CSIR-NEERI scientists began distributing NEERI-ZAR, an emergency portable water purification system, in eastern Assam. CSIR-NEERI planned distribution of 100 units for flood-hit districts Charaideo, Jorhat, and Sivasagar, with distribution planned by Monday. CSIR North East Institute of Science and Technology (CSIR-NEIST) in Jorhat assembled the filtration units for the Assam deployment.
CSIR-NEERI states that the 100 NEERI-ZAR units will be deployed as 25 community-based units and 75 household units. CSIR-NEERI also states that the combined capacity of these units is 2,500 litres of purified water per hour.
NEERI-ZAR is described as a gravity-based purification system that requires no electricity and has no operating cost. CSIR-NEERI states that the system can purify ambient water drawn from rivers, ponds, and wells by removing suspended matter, turbidity and microbial contamination.
CSIR-NEERI states that the NEERI-ZAR units are intended to ensure stable drinking-water supply for communities affected by floods in eastern Assam that began on July 19.
