摘要

Site for storing dredgings, comprising an area of land surrounded by raised walls, is adapted for also storing excess surface water. An independent claim is also included for a method for using a storage site as above for storing surface water, comprising admitting water from the drainage system of a polder into the site during a period determined by a predetermined first criterion and discharging water from the site into the drainage system of the polder during a period determined by a predetermined second criterion.
