 Water
and Wastewater Reuse - An Environmentally Sound Approach for Sustainable Urban
Water Management , Nov 2005 - Water scarcity
and water pollution pose a critical challenge in many developing countries.
In
urban
areas, it is becoming difficult for the authorities to manage water supply
and wastewater. Strategies for water and wastewater reuse can improve urban
water management.
This publication provides introductory guidelines for these strategies. The
important aspects to minimize public health risks are identified. The possibilities
of wastewater reuse in agriculture, industry, urban uses, and environmental
water enhancement including groundwater recharge are discussed with the help
of practical examples.
The capacity building policy-making, institutional strengthening, financial
mechanisms, and awareness raising and stakeholder participation are vital to
implement these strategies for wastewater reuse.
