I read the entire book when it was in its first edition and found it to be a very useful reference that covered both combined and separate sewerage systems. Now in its fourth edition, I think this is a comprehensive textbook that I would recommend to anyone studying or practising in the field of urban drainage. -- Simon Beecham, University of South Australia
