TAKING THE LOAD AND KEEPING DRY UNDERFOOT

The paper describes the development of a surface water drainage system for use in draining large paved areas, particularly in pedestrianisation schemes. The particular problems of surface water removal from such areas, usually previously areas of highway, are outlined, together with the shortcomings of the various drainage methods in use at present. The various criteria identified for the design of such channels include safety for pedestrians, harmony with surrounding paving, efficient passage of water into the units and through them and the disposal of water from adjacent rain water drainpipes. The design of the resulting drainage channel unit is described in detail and basically consists of a box and cover 600mm long by 450mm wide and 350mm in depth, drainage slits occurring where covers meet. Designed particularly for use with concrete block paving, the channel can be laid on a 50mm consolidated thickness sand bed to prevent problems of differential settlement. (TRRL)
