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.

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

This GIZ publication explains the design, use and operational requirements of composting toilets. Ample examples for composting toilets from around the world are included in the publication to show that these types of toilets have a wide range of applications under a variety of circumstances (for wealthy or poor people; for cold, hot, wet or dry climates; for urban or rural settings). The appendix contains a listing of suppliers.

From 2000 to 2006, the cross-cutting project Novaquatis explored the potential of urine source separation – also known as NoMix technology. Novaquatis comprises nine work packages, largely organized around the various stages of a nutrient cycle (e.g. user acceptation, sanitary technologies, storage and transport, urine treatment and fertiliser production, micropollutants in urine, urine-based fertilisers). The final report contains the results of all working packages as well as a practical guide for interested NoMix user.
