RAINWATER CIRCULATION SYSTEM IN AGRICULTURAL LAND CONVERTED FROM FORMER FINAL DISPOSAL SITE
PROBLEM TO BE SOLVED: To provide a rainwater circulation system capable of circulating and using rainwater in agricultural land which is converted from a former final disposal site while utilizing facilities and structures specific to the final disposal site.SOLUTION: A rainwater circulation system includes: a retaining wall 1 surrounding a former straight wall type final disposal site; plowed soil 2 which is laid and leveled on the former straight wall type final disposal site, and on which crops grow; perforated pipes 3 which collect rainwater falling on the plowed soil 2; a precipitation basin 4 in which the rainwater collected through the perforated pipes 3 is temporarily stored; a catch basin 5 in which the supernatant of the rainwater stored in the precipitation basin 4 flows and is stored; a storage pit 6 in which the rainwater stored in the catch basin 5 flows and is stored; and drain passages 7 which drain the rainwater stored in the catch basin 5.
【課題】最終処分場に固有の設備や構造体を利用しながら、最終処分場跡地利用農地における雨水を循環して用いることができる雨水循環システムを提供する。【解決手段】雨水循環システムは、直壁型最終処分場跡地の周囲を取り囲む擁壁１と、直壁型最終処分場跡地上に敷均配置され農作物が育成される作土２と、作土２に降った雨水を集水する有孔管３と、有孔管３を介して集水された雨水が一次的に貯留される沈殿枡４と、沈殿枡４に貯留された雨水の上澄みが流入して貯留される排水枡５と、排水枡５に貯留された雨水が流入して貯蔵される貯留ピット６と、排水枡５に貯留された雨水を排水する排水路７とを備える。【選択図】図１
