Water and wastewater treatment technologies are constantly evolving, employing chemists, microbiologists, botanists, and zoologists as well as engineers.

This broad and introductory textbook explains the fundamentals of hydrobiology, aquatic ecosystems, water treatment and supply, wastewater treatment and integrated catchment management -- now with coverage of the effects of climate change, environmental assessment, sustainability and the threat to biodiversity. It serves as a primer for students or practitioners in science and engineering who have an interested in freshwater biology, chemistry, microbiology or environmental engineering or who need to span these areas.
