The volumes of wastewater generated by domestic, municipal, and commercial sources have increased with population, urbanization, improved living conditions, and economic development. The use of wastewater has also increased, as millions of small-scale farmers in urban and peri-urban areas of developing countries depend on wastewater or wastewater-mixed water sources to irrigate crops for urban markets, often as they have no alternative sources of irrigation water. If used in untreated, inadequately treated or diluted forms, the undesirable constituents in wastewater can harm human health and the environment. Hence, wastewater irrigation is an issue of concern to public agencies responsible for maintaining public health and environmental quality.
The good news is that a paradigm shift is currently underway to a proactive interest in recovering water, nutrients and energy from waste streams. This webinar will undertake situation analysis about wastewater management in developing countries, highlight the potential of wastewater as a water, nutrients and energy resource, and address key challenges and opportunities in transforming wastewater as a valuable resource for a range of stakeholders.
