Based on data gained from responsible institutions like MOH Offices, hospitals, Regional Health Service Offices, Regional Secretary Offices etc, large RO Water Purification Plants will be established in areas that are highly affected by CKDu and having fewer sources of pure drinking water. These Water Purification Plants will be placed nearby the chosen wells that contain a favorable volume of water throughout the year.
The Reverse Osmosis (RO) Water Filtration Technology is determined to utilize here in order to remove all harmful elements in water such as Arsenic, Cadmium, Florid, Mercury and hardness which are suspected to be the root causes of CKDu. Thereby will be filtered and turn into pure water that is safe to drink and which can be distributed among villagers.
First, water samples from the selected location are taken and tested in laboratories at Department of Chemistry-University of Kelaniya and Jinasena private company. Then Jinasena Company designs the RO Water Purification Plant and sends the report of treated water with a sample, estimated maintenance cost of the filter and the estimate of installation of the RO Water Purification Plant. That treated water sample is tested at the laboratory in Department of Chemistry-University of Kelaniya for the final recommendation. If the quality of the treated water is satisfactory, the purification unit will be accepted. Otherwise modifications for the RO Water Purification Plant are suggested for the expected quality of water.
While confirming the order for the RO Water Purification Plant, construction of the filter plant room will be commenced. A sketch of the building is sent by an architect to design the plan of the filter plant room. Then this plan is sent to a quantity surveyor to estimate requiring quantities of building materials. After receiving quantity surveyor’s report quotations for listed building materials are taken from suppliers in the vicinity of the construction. After selecting the suppliers, building materials are ordered and the Civil Security Department of the area provides man-power for constructions of the filter plant room.
After completing the construction of the filter plant room, Jinasena private company is asked to install the Water Purification Plant. Following installation of the RO Water Purification Plant, pure water is served to people.
