wasted, National Water Supply and Drainage Board chairman Karunasena

income settlements and administrative and commercial loopholes have
contributed to this wastage in Colombo. He said the highest amount of
water consumption is in Colombo city due to the high density of
population and water connections.
He noted that the national average of water wastage referred to as
"non revenue water" in Sri Lanka is about 30 per cent.
He noted the international standard of this rate is 20 to 18 per
He also said that water wastage rate is 20 per cent in Battaramulla
and 11 per cent in Maharagama.
He requested the active support of the public to reduce water wastage
especially in Colombo.
The chairman also observed that the expenses for water supply has
been increasing day by day due to the electricity tariff hike, the
depreciation of the rupee, increase in manpower charges and other
expenses borne by the Board.
He said that the Board is compelled to increase the water tariff
under these circumstances adding that the final decision would be made
by the National Water Supply and Drainage and Finance and Planning

last three years despite the increasing cost of production.
