The facility for collection of rain water in all
building will be mandatory in the future. All buildings plans
will have to include a tank for collection of rain water which
is to be used for purposes other than drinking, Urban
Development and Water Supply Minister Dinesh Gunawardane, told a
media briefing held to announce the progress of the Kalu Ganga
Water Supply Project and the improvement of the water supply
system in the Matara District.
Water resources are not unlimited and even
though we have not faced a scarcity of water, we have to be
careful in order to avoid a problem in the future. Our people
have cooperated but more could be done, the Minister said.
"We must realize that purification of water
entails very heavy expenditure. Thus we need to appreciate that
using drinking water, processed at a heavy cost, should not be
used for washing of vehicles, watering of gardens, bathing of
cattle or for toilet purposes and other uses for which the use
of drinking water is an absolute abuse of scarce resources", he
The National Water Supply and Drainage Board
incurs a cost of Rs. 22 to purify one unit of water which is
sold to consumers to Rs. 1.25. The unit is equivalent to 1000
litres and comparing the cost of a bottle of table water
marketed by the private sector is worth over Rs. 30,000.
Our people should not close up the wells in
their gardens when they are provided with pipe borne water but
rather continue to use the well water for all uses other than
for consumption. The concept of a twin supply of water, one for
consumption and the other of a quality less than that needed for
drinking/consumption should be implemented as is done in many
The new schemes, both the Kalu Ganga and Matara
Water Supply Systems will provide pipe borne water to consumers
in Moratuwa, Panadura, Bandaragama, Horana, Matara Pradeshiya
area, Devinuwara Pradeshiya area and Dickwella.
The Kalu Ganga project will include the
construction of a water treatment plant with a capacity of 13.2
million gallons per day resulting in a service improvement to
400,000 existing consumers and a potential for 100,000 new
connections in the Southern part of Greater Colombo and lesser
towns of the Kalutara District.
An expansion of capacity would result from the
improvement of the Water Supply System in the Matara District,
increasing the present capacity of 6.6 million gallons per day
to 9.9 million gallons per day, he said.
