The Wallingford Procedure for the design and analysis of urban drainage systems was released in late 1981 for use by drainage engineers in the United Kingdom. This was the most significant British event in urban hydrology and in drainage engineering in the period covered by this report - indeed for a considerably longer period. Many of the drainage networks in the older urban areas of the United Kingdom are over a hundred years old. Some of these systems are still providing an adequate service, others are in serious need of improvement, rehabilitation or replacement. An extensive program of research has aimed at achieving the optimum benefit from existing assets; the work included alternative methods of rehabilitating old drainage systems and the joint use of flow surveys and computer simulations to assess hydraulic performance.
