Research & Development Section of National Water Supply and Drainage Board has been established to innovate new technologies on water supply activities in the organization.

Research & Development Departments are common in many larger organizations, especially those working with newer products or technologies.  At present the government target is to meet 100% safe drinking water coverage in the country and increase pipe born water supply coverage to 60% by year 2020 where as at present safe water coverage is 85% and the pipe born coverage is about 45%.

Due to human activites, water quality is deteriorating day by day and water supply is becoming challenging task with climate change.

Therefore task of the R&D section is to selection of appropriate technologies and optimization of cost.  R&D section is actively involved in monitoring of Reverse Osmosis Plants installed in North Central Province where Chronic Kidney Disease patients are present.

Vision

Identify and implement economic sustainable means of providing potable water to people of Sri Lanka while minimizing environmental pollution.

Mission

Exploit Local expertise and material as far as possible to succeed with application oriented research activities
