A water storage cell ( 2 ) is positioned underneath a pavement ( 4 ). An upper boundary of the cell ( 2 ) is formed by a surface ( 6 ) or wearing course of the pavement ( 4 ). The remaining boundary of the cell is defined by a water-retaining layer ( 8 ) that may pen-nit infiltration of water into the surrounding ground. Means for enhancing the evaporation rate of the water in the cell are provided. As shown a ventilated pathway ( 20 ) extends between a vent ( 22 ) and a flue ( 24 ) and is surrounded by means such as a liner, suspended dished panels, absorbent mats ( 32 ) or particulate material with surface absorbency characteristics to detain water in contact with the airflow in the pathway ( 20 ). The cell ( 2 ) can be used in a SUDS system without an outfall with both permeable and impermeable pavements.
