In many countries, a rapidly upcoming demand for decentralised
wastewater treatment systems (DEWATS) and a demand for efficient
community-based sanitation (CBS) can be observed. DEWATS is designed to
be an element of a comprehensive strategy for city-wide planning and
sustainable infrastructure development. In this book, not only are the
technical requirements for the efficient treatment of wastewater at a
given location explained, but the specific socio-economic conditions and
steps for community action planning are also taken into consideration.
