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.

Saltsjoe-Boo (Sweeden): Wostman Ecology AB URL [Visita: 13.05.2019]Waterless urinals save water and they allow the collection of undiluted urine, which – because of its nitrogen and phosphorus content - is a valuable resource as fertiliser in agriculture. 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.
