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.

The report investigates access to and use of drinking water in greater detail than is possible in the regular JMP progress reports, and includes increased disaggregation of water service levels and analyses of trends across countries and regions. It focuses on the three key challenges of equity, safety and sustainability.

Typically, the large urban areas represent concentrated demands, both due to large populations and large per capita use and waste. 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

These guidelines were developed for the construction and management of rural water supply and sanitation facilities. It is a collection of global and national good practices in water and sanitation that have been collated. These simple guidelines are primarily intended as a reference for field staff and practitioners in the water and sanitation sector challenged by situations and conditions in the field.

This review focuses on decentralised systems that treat the potable water (drinking and cooking) of a single household (point-of-use systems) or a community (small-scale systems). 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.

Behind headline successes in providing first-time access to water lie a number of pressing challenges to the dominant approach to rural water supply in developing countries, namely community management following a demand-responsive approach. These challenges manifest themselves in poor performance of service providers, high rates of hardware failure, and very low levels of service. This paper argues that tackling these challenges requires a shift in emphasis in rural water supply in developing countries: away from a de-facto focus on the provision of hardware for first-time access towards the proper use of installed hardware as the basis for universal access to rural water services.
