![]() ![]() Industry is a major water consumer and wastewater discharger. Wastewater can be used in ‘industrial symbiosis’. Improved wastewater management can improve the health of agricultural workers by reducing the risk of pathogen exposure. Wastewater is a valuable source of both water and nutrient content for crops, contributing to water and food security and livelihood improvements. The positive impacts on water quality and supply by increasing wastewater recycling and safe reuse will drive progress in public health, environmental sustainability and economic development by providing new business opportunities and creating more ‘green’ jobs. There are many treatment processes and operational systems that use wastewater in municipal activities, sustainable agriculture, energy production and industrial development.īenefits far outweigh the costs of better wastewater management. Safely managed wastewater is an affordable and sustainable source of water, energy, nutrients and other recoverable materials. ![]() Governments must exploit the enormous opportunities in wastewater. Household effluent, human waste, toxic chemicals and medical waste are exposed to the air, contaminating the environment in often densely-populated residential zones. In poorer urban areas, a large proportion of wastewater is discharged untreated directly into the closest drainage channel or water body. Untreated wastewater in cities is a major issue. Across the world, safely reused wastewater is grossly undervalued as a potentially affordable and sustainable source of water, energy, nutrients and other recoverable materials. ![]() Wastewater management is being seriously neglected. Industry in many areas still discharges waste directly into water courses. Increased usage of chemical fertilizers and pesticides, and untreated wastewater in irrigation, pollutes groundwater and surface water. Industry and agriculture are often big water polluters. Due to population growth, accelerated urbanization and economic development, the quantity of wastewater being generated and its overall pollution load are increasing globally. Water pollution is increasing throughout the water cycle. ![]()
