The project, which was launched under a concessional loan from the China Development Bank (CDB), was suspended between May 2022 and May 2024 due to the country's debt restructuring process. However, recognising its national importance, the current Government allocated additional funding from the Government of Sri Lanka to successfully complete the project.

Constructed as a long-term solution to the chronic kidney disease that has spread rapidly across the region, the water supply project is also expected to improve the social and economic well-being of local communities.

The project aims to provide 25,000 new household water connections. Built at a cost of Rs. 32 billion, the project comprises a water treatment plant with a daily capacity of 18,000 cubic metres, three water towers with a capacity of 1,500 cubic metres each, a 12.75-kilometre water transmission pipeline and a 158-kilometre water distribution network.

Speaking at the event, Minister of Housing, Construction and Water Supply Susil Ranasinghe said:

"The Thambuttegama Water Supply Project, which was declared open today by the President, has the capacity to provide safe drinking water to 25,000 families. The project has been completed at a cost of Rs. 32 billion. It was implemented with the assistance of the China Development Bank, but construction came to a standstill due to the economic crisis experienced in recent years. Over the past two years, we allocated funds through the national budget and have now successfully completed the project.

At the initial stage of the project, concerns were raised over drawing water from the Rajanganaya Reservoir. Farmers protested against the proposal. However, today this project is being commissioned with the blessing and support of the Rajanganaya farmer leaders, who are present here. They presented their concerns to us and we are committed to addressing them.

Their foremost concern was to ensure that no farmer in Rajanganaya would face a shortage of irrigation water as a result of water being diverted for this project. I can assure you without hesitation that there is absolutely no reason for concern. Not even a single drop of water required for agriculture will be denied in order to supply drinking water. This project is, after all, intended to provide clean drinking water to farming families themselves.

They also requested that compensation be paid if cultivation is affected due to any water-related issue. I assure you that there is no cause for concern on that front either. This Government has consistently compensated farmers affected by disasters. We paid Rs. 1.2 billion in compensation for losses suffered by farmers over the past seven cultivation seasons due to the Nilwala saltwater barrier. We also resolved long-standing issues relating to land acquisition under the Yan Oya Project and allocated Rs. 180 million to the District Secretary to compensate the affected landowners. In addition, Rs. 12 billion has been paid in compensation to around 200,000 farmers whose farmlands were damaged by Cyclone Ditwah. Therefore, if farmers suffer any losses or damage to their lands in the future, this Government stands ready to provide compensation.

Another request made by the farming community was the construction of the Ginipetti Bridge if water is to be drawn for this project. We have already allocated Rs. 240 million to build a new bridge capable of accommodating vehicular traffic and foundation work will commence shortly. At the same time, a team of experts has been appointed to determine whether the existing Ginipetti Bridge can be rehabilitated or whether an entirely new bridge is required. Therefore, I assure the farming community once again that we will not allow them to suffer any hardship or loss as a result of this project."

Minister of Trade, Commerce, Food Security and Cooperative Development Wasantha Samarasinghe, Governor of the North Central Province Wasantha Jinadasa, public representatives of the province, Chinese Ambassador Qi Zhenhong, officials of the Ministry of Housing, Construction and Water Supply and the National Water Supply and Drainage Board, together with a large number of local residents, were also present at the event.
