The Science of Sewage

Most of us don''t think about what happens when we flush - until raw sewage appears where it isn''t wanted, on our beaches or pouring into rivers. Yet enormous quantities of offensive and hazardous organic waste and dirty water are flushed into the sewers every day. So how exactly is it all cleaned up?

As Julian Doberski explains in this, his latest book, there''s a certain biological magic in the cyclical process of turning sewage into river water, river water into drinking water and drinking water back into sewage. The Science of Sewage shines a light on this highly technical and complex operation.

Beginning with a look at how societies have attempted to deal with their waste - and avoid devastating waterborne diseases - throughout history, The Science of Sewage goes on to briefly review the current structure and ownership of the UK''s ''water services''. The book then considers how the biological health of our natural water bodies is assessed, and the impact of sewage pollution on the finely balanced ecosystems within our rivers, lakes and coastal waters.

Julian Doberski explores the biological and technological options and challenges of turning domestic wastewater into effluent that can be safely discharged, revealing exactly what goes on in a sewage treatment works. This fascinating book then concludes by highlighting our collective responsibility - whether as citizens, public or private water service companies, or government and government regulatory bodies - for ensuring the quality of our water and the health of our environment.
