This book provides a holistic and clear understanding of water supply, sanitary and storm drainage systems for buildings: one-story to skyscrapers, to be built in both the developed and underdeveloped areas. It describes the systems and their entire components - major to minor - and provides exclusive guidelines for the planning, design, installation and maintenance of the systems. The book starts with an introduction to the systems, and ends with a chapter on the presentation of the systems in drawings, others being discussions on all the components, devices, equipment etc., in their respective dedicated chapters – discussing: Pipe, Fittings, Accessories, and Appurtenance; Pumping and Pumping Systems; Water and Hot Water Supply Systems in Building; Appliances and Fixtures; Building Sanitary Drainage; Off-site Sewage Disposal; On-site Sewage Management; Drainage of Storm Water; and Water Supply and Drainage Planning. Written and the figures are drawn by an author of three engineering books of international repute, the last being the 2nd edition of the first one, who served the Public Works Department of Bangladesh - a national building development authority - for more than 35 years. This book is the fallout of practical experience in the building industry, teaching in universities, facilitating training and sharing thoughts in seminars and symposiums on related subject-matters, since the early 90s until today. Figures being drawn by the author using a rarely-used drawing tool help provide additional attraction to the readers. Additionally, the inclusion of worked out examples of designing the major system-components will undoubtedly bring utmost satisfaction to its readers. This book will be helpful for use in a wide range of courses, both undergraduate and post-graduate degree programs, related to building, environmental and civil engineering, architecture, and many more. Building service professionals will benefit greatly. Other traders, administrators in this field, and policy-makers would not be left out of the beneficiaries as well.
