Construction workers install low-pressure water pipelines in Heze, East China's Shandong province on Jan 24. Water conservancy programs are under construction to relieve local farmlands hit by a recent drought. China will strive to improve the country's underdeveloped water conservancy works over the next five to 10 years, according to a document issued jointly by the Central Committee of the Communist Party of China and the State Council, China's cabinet on Saturday.
