The Services rendered by North Western RSC of N.W.S.& D.B. for patients suffering from kidney disease in Kurunegala district

The data bank of the Department of Health reveals that the no. of CKDu patients in 11 no. of MOH divisions in the Kurunegala district is increasing rapidly. The quality of drinking water could be a major component for the increase of CKDu patients. Hence the N.W.S.& D.B. has initiated no. of projects in these areas.
• In the Polpithigama and Maho MOH divisions, 252 kidney patients have been provided with 250 no.s of Rain water collecting tanks with capacity of 2000 L.
• 25 no.s selected schools in the above areas have been provided with 41 Rain water collecting tanks with capacity of 5000 L.
• Work has commenced for restoring hand pumps and extending the distribution line to supply water from the Maho WSS to these affected areas.
• In addition to this we have lounged a joint programme along with the DHS office in Kurunegala to monitor the quality of drinking water sources (Dug wells) of these affected areas namely Polpithigama, Giribawa and Galgamuwa.


The major task of the Sector Planning section is preparation of proposals for new projects to improve the water supply coverage in the North Western Province. Apart from that, the section has planned and achieved following goals.

*Preparation of water supply coverage maps of existing as well as proposed schemes

*Preparation of a database of water supply coverage details about GN Divisions in North Western province

There are major schemes to prepare pre-feasibility reports by the sector planning section of North Western since the availability of water is limited. They can be classified as foreign funded & local funded projects. Except these two categories, still there are few schemes for which no any fund identified yet.

PAC approved projects are Galageda –Mawathagama, Alawwa-Polgahawela, Melsiripura, Galagamuwa, Pannala-Makandura –Kuliyapitiya, Deduruoya, Hiripitiya-Ganewatta in Kurunegala District & Anamaduwa, Dankotuwa, Kalpitiya & Towns South of  Puttlam in Puttlam District.

By implementing   all the above proposed projects, the water supply coverage will be increased up to 67% in Kurunegala District & 81% in Puttalam District.
