580000 poor people in Tibet basically solve the problem of drinking water safety
Xinhua News Agency, Lhasa, November 7 (Reporter Liu Hongming and Tian Jinwen) the reporter learned from the Water Resources Department of the Tibet Autonomous region on the 6th that so far, there are 24304 rural drinking water safety projects in Tibet, benefiting 2.4787 million people. Among them, the problem of drinking water safety for 588700 people living in poverty has been basically solved, and the centralized water supply rate of rural drinking water projects has reached 91.82%.
Due to the influence of natural climate, the water quantity of water supply sources in some rural areas in Tibet varies greatly, especially in some alpine counties in winter, with low temperature, thick permafrost layer and long freezing period. In winter, the freezing damage of water supply pipes and equipment is serious, and the guarantee rate of water supply is low. It directly affects the water intake and water use of farmers and herdsmen.
In this regard, the Tibetan water conservancy department has divided the alpine areas in northwest Tibet, the alpine canyon areas in the east, the southern border areas, and the central river valleys into four areas, adapting measures to local conditions, and strictly requiring the design, construction, and materials of the project. We should try our best to meet the requirements of water supply and water quality in high and cold areas. At present, 15 rural drinking water quality testing centers have been built in the region.
In view of the fact that the faucet is easy to freeze in winter and the water source is difficult to supply water in winter, Nimu Township, Bianba County, Changdu City, explores the technical model of "anti-freezing faucet + regulating reservoir + pipe network extension". Chomei County, Shannan City, built small reservoirs in each village, 24 hours of continuous water supply in winter to prevent pipes and faucets from freezing, reservoir temporary storage to avoid the waste of water resources.
It is estimated that by the end of 2020, the problem of drinking water safety for all poor people living in Tibet will be basically solved, providing rural drinking water safety support for accurate poverty alleviation and rural revitalization.
