This handbook describes the methods and procedures of the Rapid assessment of drinking-water quality (RADWQ) applied by WHO and UNICEF to explore the quality of drinking-water from "improved" sources in five countries. The handbook is for adoption by any authority or institution that wants to prepare a snapshot of the quality of "improved" sources of drinking-water, as a first step towards strengthening drinking-water quality regulations.

In the context of African developing countries, costs and maintenance requirements of waterless urinals need to be as low as possible. Despite the fact that hundreds of thousands of waterless (and odourless) urinals are now already in use worldwide, many municipalities are not yet aware of their existence or are reluctant to accept them as a viable option. This paper aims to reduce this knowledge gap by describing available models, odour control methods in waterless urinals (flat rubber tube, silicon curtain valve or sealant liquid), and the aspects to be considered regarding maintenance requirements and costs.

These guidelines aim to impart knowledge about water loss reduction to decision-makers and stakeholders at the national level and to the management team, planning and design department and operating staff at local water utilities in developing and transition countries. The guidelines are accompanied by capacity development materials as well as the implementation of pilot projects in order to transfer know-how and implement state-of-the art pressure management (PM) technology in practice.

Most urban areas have depleted, polluted or destroyed their local sources of water like rivers, lakes and tanks and in many cases even groundwater. This case study presentsdecentralised approach where powers are devolved to local institutions and where co-ordination among the state, private sector and civil society are ensured for evolving water supply options

For application in developing and transition countries, important boundary conditions for decentralised systems include low costs, ease of use, sustainability, low maintenance and independence of utilities (energy sources). Although some low-cost systems are available, their application is limited by time-consuming daily operation and maintenance. Other systems are too expensive for the poor populations of developing and transition countries and in most cases do not fulfil the system requirements described above. Point-of-use systems based on membranes are commercially available and are designed to operate on tap pressure or gravity.
