This document is addressed to planners and staff of water supply and sanitation projects on household and community level. The reader is guided through the main steps of informed choices regarding the main proven technologies for water supply, purification and water treatment at household and community level. Each technology is described in a small factsheet, regarding its functioning, actors and their roles, the main operation and maintenance (O&M) requirements and problems, which can occur.

This very comprehensive technical paper includes important background information, a detailed description of the principle of slow sand filtration and much information on the construction, design and implementation of slow sand filtration plants.

Desalination technologies typically require high energy inputs, as well as specialized maintenance procedures, to function sustainably – rendering them inappropriate for water production in low-income areas. The focus of this paper is the development of a ‘Road Map’ for scalable, low energy-input solutions for small-scale desalination.

The report suggests that emerging trends in low-cost, decentralised naturally-based infrastructure and urban wastewater management which promote the recovery and reuse of wastewater resources are increasingly relevant. Technologies for these sanitation options are presented. The concept of managing urban wastewater flows at a decentralised or "intermediate" level, based on micro watersheds, is explored. Effluent treatment standards that are currently accepted in order to protect public health and safety are reviewed.
