A GUIDE FOR ENGINEERS TO THE DESIGN OF STORM SEWER SYSTEMS. ROAD NOTE 35. SECOND EDITION

In 1963, the first edition of Road Note 35 was published as a guide for engineers in the use of the RRL hydrograph method. Since then, the method has become the most commonly applied surface water sewer design method in the United Kingdom. Through experience of its use there have been modifications to the basic method and to the rainfall input and most recently the units used in the calculation have been metricated. This revised note incorporates these changes, and also advises on such problems as carrier sewers and cases where natural streams are diverted into surface water sewer systems. Programs for larger and more versatile computers have been written. The opportunity has also been taken to use a slightly more general form of the hydrograph method than was used in the original computer programs. As far as the engineer is concerned these changes manifest themselves only in a more detailed print-out of the results and the removal of the need to specify an estimated sewer volume when the sub-area technique is used. /TRRL/
