摘要： This invention provides a clean water system and structure that positively utilize the natural water purification system present in rivers, the ocean and other natural water bodies to prevent water fouling and stench over the long term and enable low-cost maintenance of ponds and the like. For this, water current producing means is constituted of an underwater pump (2) installed at one end of a pond (1) and an outlet (3) that discharges water pumped by the underwater pump (2) at the other end of the pond, a sand layer (4) is spread to a prescribed depth on a bottom (10) of the pond, and carp or other swimming fishes (5) are allowed to swim in the water as secondary consumers in the food chain. Negative pressure produced at an inlet (20) of the underwater pump (2) sucks water into the inlet (20) to produce movement of water in the pond such as causes water immediately under the outlet (3) to migrate toward the inlet (20). Thus a clean water system and structure are constituted wherein the water is kept in motion to constantly supply oxygen to the entire pond (1) and prevent stagnation, thereby creating an environment in which the food-chain effect can easily operate, and the water is purified by the food-chain phenomenon among the organisms living in the pond (1).

摘要： A clean water system, and a structure thereof, capable of preventing contamination of water and offensive odor for a long time by positively utilizing a purification system of water existing in the natural world such as rivers and seas and capable of managing ponds, etc, at a low cost, wherein water flow generation means is formed comprising an underwater pump (2) provided at one of the ends of a pond (1) and a discharged port (3) for discharging water sucked by the submerged pump (2) from the other end of the point, and a sand layer (4) is formed on the water bottom to a predetermined thickness from the bottom surface (10) to allow fish (5) such as carp as secondary consumers in the food chain to swim. Water is always moved to supply oxygen throughout the pond (1), to prevent water from stagnating and to create an environment in which the food chain functions more easily and to purify water by the function of the food chain of creatures living in the pond (1).
