Mud, dust, rust, and metal sediment
Foul odor and discolored water
Critical Health Warning
Even when water looks clear, studies show over 60% of rooftop tanks in Dhaka test positive for bacteria like E. coli and Salmonella. Regular cleaning is not optional — it’s essential for your family’s safety and hygiene.
