Recycling the Resource
This book focuses on treatment approaches that include a recycling loop for the water, nutrients, energy, and other resources in wastewater. The preliminary indications are that decentralized, re-circulating systems for wastewater treatment can be significantly cheaper than the building and maintaining of conventional systems.
Oneday, wastewater will be an antiquated expression; synonymous with 'wasting water'. It will then be considered to be as natural to re-use wastewater's resources as it is now for farmers to plow wheat stubble back into the ground.
