This article takes Dongsheng District reclaimed water utilization project in Erdos as an example to discuss the ecological design of urban reclaimed water utilization system. Through the forecast of water demand of reclaimed water in urban areas, the water balance analysis was carried out. The urban reclaimed water utilization system combined with ecological landscape facilities fully utilized the transportation, storage, allocation and purification functions of ecological watercourses and wetland parks to achieve a virtuous circle of water ecology and ease The situation of shortage of local water resources; In addition, introduced the design of the key nodes such as water pumping stations and landscape water recharge points.
