1. Water conveyance system water-saving technology By strengthening the water storage, water diversion project maintenance and construction of supporting facilities, the existing irrigation canals to take lining, seepage and other transformation measures to increase the water storage capacity and reduce the leakage of water loss system. Actively promote the “U” -type drainage and pipeline lining technology, the technology is simple production process, construction convenience, compared with the soil can reduce water leakage 60% to 90%, suitable
