JAFFNA PENINSULA DRINKING WATER
However, some flood reduction could be readily achieved by:
1. Cleaning and keeping clean the existing canal, pond, and outlet network;
2. Installing, operating and maintaining rooftop water capture and post-flood release (Fig. 8); and
3. Increasing the storage capacity of the aquifer by blast- ing and tunneling.
Running the project turned out to be complicated because the client required the team leader to live in and work from the Jaffna House, while the local technical team of part- time, consultants lived and worked in the capital Colombo, 393 kilometers to the south.
An added complication was that Jaffna was at the epi-
center of the 30 years long civil war between the minority Tamil-speaking Hindu population and the national gov- ernment
The work encountered several technical challenges due to the lack of rainfall and runoff records appropriate for
The Civil War devastated Jaffna and left it as the poorest and most neglected region of the country. For example, there is no functional civil airport, and there is an extensive military presence.
numerical modeling of stormwater drainage. This was overcome somewhat by information provided by community members on the 2014 and 2015 floods, by land and aerial surveys, and by satellite maps.
