About this book
Focusing on operational practicality, Sustainable Wells: Maintenance, Problem Prevention, and Rehabilitation serves as a comprehensive guide to state-of-the-art performance maintenance, prevention, and rehabilitation. This book addresses design features to maximize sustainability and cost-effectiveness issues in planning. It covers directional, horizontal, and vertical wells for water abstraction, recharge, barrier, and monitoring applications in both developed and developing countries. Including spreadsheets for readers to design and follow as well as recommendations based on historical performance, this text provides a single source for information on well sustainability.
