Lai advocates that the current competition between residential, industrial and agricultural users should be reoriented into a cooperative relationship. Because residential and industrial users have relatively little demand, it's not easy to independently develop water sources for them. He thinks everyone ought to cooperate to collect rainwater and divert river water, and thus build locally based systems of water resources-the path of "storing the water on the farms."
此外他也呼籲，應將農業和民生、工業用水的競爭關係調整為合作關係，因為民生或工業用水量小，不容易獨立開發水源，大家應合作開發，攔蓄雨水及河川逕流，建立地區性的水資源系統，這就是所謂的「藏水於農」。
