“The government is going to amend the country’s ‘building code’ to make harvesting of rain water mandatory for all the buildings as the level of ground water is falling fast because of excessive use.
Sheikh Abdul Mannan, a member of Rajuk (planning), has said that the government wanted to encourage the builders so that they keep provisions for rooftop harvesting of rain waters. The developers can also preserve rain water in any ground facilities if roofs are not an option for them.
But it is going to be binding for them one way or the other.
He said a new provision titled, ‘Rain Water Harvesting and Ground Water Recharging’ will be punched in the ‘Dhaka Mahanagar Building (Construction, Development, Protection and Removal) Rule’ enacted in 2008.
“The provision must be included in all building plans from 2012 if the code is amended by the end of this year,” he said.
Local government minister Syed Ashraful Islam on Tuesday told parliament that the government was working on ensuring collection of 70 percent water demanded in the capital city of Dhaka from rainwater and water holes in the next 10 years.
Engineer Mannan said 87 percent of water requirements in the city came from underground source, 13 percent from the Buriganga and the Shitalkkhya rivers.
“The water of these rivers has become unfit for use even after refining,” he said.
“Dependence on ground water is increasing to meet the demand. As a result, the level of ground water is decreasing two-three metres (eight-10 feet) every year, which raises fears of landslide. In this situation, use of surface water is being emphasised,” he added.”
