Based on the lessons from home and overseas study and investigation and construction in situ, different types ofdemonstration projectswere successfully mi plemented in Tianjin, Cangzhou, HengshuiandJiyang, such as radialwellofpumping saltwaterand replacing freshwater , recyclingwellof riverwaterrain floodsphreaticwater , enhancing pumpagewellby siphoneconectivityway and has achieved good results under the condition of lowcost. It has not only solved the problem of irrigation water shortage in fresh water, brackish water, even salt water distribution areas, but also made largescale utilization of shallow saltwater become possibility, and provide a feasib
