REVERSE WELLS FOR RAINWATER COLLECTION TO COMBAT LOCALIZED FLOODING IN URBAN AREAS

Abstract

This useful solution in the field of urban drainage aims to accelerate the drainage of rainwater into the ground to prevent localized flooding in urban areas, solve the problem of dead lakes in cities, and conserve rainwater resources. Specifically, the proposed solution is an inverted rainwater well consisting of a well body filled with gravel or construction stone, and a deep drainage section comprising one or more vertically arranged drainage pipes extending from the bottom of the well body and connecting to the bottom of the well body. These deep drainage pipes are filled with gravel or construction stone with a maximum size ranging from 1 to 10 cm, with the difference being that the maximum size of the gravel or construction stone is between 1 and 2 cm, accounting for 70 to 90% of the total gravel or construction stone used.
