The utility model relates to a reclaimed water irrigation system, in which a pipeline is connected with a human pressure boosting mechanism. The manpower supercharging mechanism includes two cranks and a pressure cylinder. These cranks move alternately to achieve the purpose of fitness. They also change the pressure value of the pressure cylinder and draw the reclaimed water through the pipeline for irrigation. The reclaimed water comes from a sewage recycling device, which can convert the sewage into relatively clean reclaimed water for plant irrigation, with the purpose of energy conservation, carbon reduction and water saving.一種中水灌溉系統,用一管路連接一人力增壓機構。該人力增壓機構包括二曲柄與一壓力缸,這些曲柄交錯運動,達到健身目的,兼具壓力缸的壓力值改變,通過管路汲取再生水用於灌溉作業。所述的再生水來自於一污水回收再利用裝置,可將污水轉換成比較乾淨的再生水,用於植物的灌溉,深具節能、減碳及省水等目的。
