Rainwater could meet up to 60 per cent water demand at garment manufacturing units in Bangladesh even as rainwater harvesting currently meets 15 per cent to 60 per cent of the demand for non-drinkable water at textile and garment units, helping the industry further in its green movement by reducing dependence on groundwater.
This was, reportedly, underlined by a study released recently and conducted jointly by RAiN Forum and the WaterAid, according to which, of the 65 textile and garment manufacturers surveyed, 53 factories have catchment areas ranging from 2,000 to 8,000 square metres, while 12 units have rainwater catchment areas of 2,000 square metres even as it added the annual demand for non-drinkable water in 17 of these factories is 10,000 cubic metres, while in the remaining 48 units, it ranges between 10,000 and 50,000 cubic metres.
It may be mentioned here currently Bangladesh is the global leader in terms of green garment factories with 157 Leadership in Environmental and Energy in Design (LEED) certified units across the country even if these green garment factories have been saving an annual average of 40 per cent on their power and water costs by introducing rainwater harvesting.
