 Also, construction of embankments through low-lying areas without providing adequate drainage facilities had caused internal flooding.According to background information for a representative survey conducted for the Asian Development Bank in 2005, out of the 12 million inhabitants of Dhaka, the Dhaka water utility provided drinking water for 9 million through house connections, as well as for an additional 600,000 through 1700 standpipes and 100,000 through bulk connections.Bulk connections are located in slums and are known as "Water Points".
