This book provides instruction and guidance on the evaluation and decision making processes involved in the conception and realisation of water and wastewater engineering projects. The author addresses the problem of project development in the water industry and leads the reader, with the help of hypothetical case studies, through the process of problem evaluation, developing conceptual designs and costings. Readers are finally instructed on presenting their solutions in the form of an effective engineering report. Water and Wastewater Project Development presents and resolves problems in engaging and innovative ways that seek to actively include the reader in decision making exercises. At each step of the book the reader is given a brief resume of the necessary theory and technical information necessary to apply the techniques proposed. Emphasis is placed on the use of worked examples and case studies that develop and evolve throughout the text. As such, this text is ideal for the practicing water engineer, the postgraduate student, and those with involvement in issues of environmental concern and management.
