The Urban Context
The large volumes of untreated wastewater produced by rising urban population growth trends and increased water consumption in recent years is a concern for WASH (Water, Sanitation and Hygiene) sector agencies located in secondary cities and towns. The situation is complicated by the fact that poor urban farmers often turn to untreated wastewater as a welcome source of water and nutrients for agriculture. The unregulated use of wastewater poses serious risks to human health and the environment. Although many countries have regulations governing wastewater use, these regulations are hardly ever enforced. Another weakness is that knowledge and information is not available in a practical form for planning and implementation. |
