River water-fetching device

A new river water-taking device comprises a well body and a filtering body. A frame structure made of beams and poles and a well wall made of big hole concrete are arranged around the well body. The filtering body is a sand stone pile body whose section is an inversed trapezoid. The lower layer is a water storage layer made of big stones and middle-sized stones. The central layer is a filtering layer made of small stones; and the upper layer is a filtering layer made of coarse sand and medium sand. Compared with ordinary water plants, the utility model can save investment, land, energy and electricity. No pollution is caused to the water and zero emission is realized. Meanwhile, the low operation cost cuts down water supply cost.
