The focus of the study is on the impact of the programmes at the level of the end beneficiaries. Main effect variables taken up in the impact analysis are quality and quantity of the drinking water that is supplied and consumed, the actual use of improved water sources and sanitation facilities, hygiene behaviour, the time burden of water collection, the use of time savings for schooling and/or economic activities, the health effects and costs, and the financial viability of the investment and fee structure. The study also addresses differences in benefits across socio-economic groups, and differences between the dry and rainy season. The study has been designed with the explicit aim of providing quantitative evidence on the effects that can be attributed to the interventions by comparing changes over time and between households with (treatment) and without (control) programme interventions. The interventions studied are water supply infrastructure (manual pumps and small piped systems), public latrine buildings and hygiene promotion.

IWMI research in Ghana suggests that poor access to irrigation may discourage some women from taking up urban farming, but men also feel disadvantaged by female domination of the marketing sector.

Urine can be reused as urea, while faeces are dried in a double vault system of alternate use. The moisture comes out using ventilation pipes. After 2 years the end product can be emptied and reused without having any health risk. Water from washing can be treated in a constructed wetland and reused for instance for irrigation.

This is an article on how to remove radioactive iodine-131 from drinking water, talking about different technologies including ion exchange.
This web link describes the use of ion exchangers and their use in wastewater treatment, including theoretical and practical information.
The aim of this manual is to describe the variety of work as well as to provide a survey of the types of materials used in rural water supply construction.
