The Blair Research Bulletins are already established, the world over, as leading documents in the complex issue of water supply: building, maintaining and producing quality water supply whilst giving priority to the safety standards and hygienic control of the water. This book brings together many of these bulletins as a filed manual with improved illustrative material and the most modern refinements to techniques and ideas. The text describes principles of design and basic concepts which designers can adapt to suit local conditions. Instructional notes are provided for many sections. Notes are also given on implementation with regard to human resources and conditions.
