“…It implies that the water quality had an impact on the contamination, although all samples were within the satisfactory range for consumption. The differences certainly occurred because the tap water from Maputo City is treated with chemicals such as chlorine [25]. Underground water is prone to contamination and it can have high levels of coliforms if not treated [26,27].…”

Markets from Maputo City have been reported to have poorly hygienic premises and sellers unaware of the safest food handling practices. This study aimed to analyze associations between some lettuce (Lactuca sativa) handling features and the levels of total, fecal coliforms and Escherichia coli. Cabbage was purchased in the 3 markets. Just before the acquisition, the researchers recorded the source of water used to wash it, if they were sold in booths or on the floor, if they were sold mixed with other products, and if the sellers were wearing gloves. The cabbage heads (42) were analyzed through the technique of multiple tubes to estimate the most probable number. Average levels were 14.43 MPN/g for total coliforms, 13.9 MPN/g for fecal coliforms and 12.02 MPN/g for E. coli. The highest levels of contamination seemed associated with the use of well water, the food sold on the floor, the lettuce sold together with other products and the lack of gloves. The mixture of products only showed a major impact on the level of E. coli (p < 0.001). Yet, all levels were within the satisfactory range, according to the guidelines from The International Commission on Microbiological Specifications for Foods (ICMSF).

“…Results reported after 4 years of operation showed the high efficiency of the UF process in the removal of total coliforms, indicating their complete absence. Only some samples taken at the point of use during the summer season showed a slight presence of microbiological contamination associated with coliforms, which resulted in the introduction of a post-treatment stage that improved water quality [39]. As in the other cases, permeate is chlorinated to prevent microbiological recontamination of the water.…”

Access to drinking water is a basic human right which has become an international goal. However, despite the efforts made in the framework of the Millennium Development Goals of the United Nations, about 700 million people are still without access to an adequate source of drinking water in rural areas of developing countries, especially in Africa Sub-Saharan. The AQUAPOT project, developed by the "Instituto Universitario de Seguridad, Radiofísica y Medioambiental (ISIRYM)" of the "Universitat Politècnica de València (UPV)", both in Spain, has been focused research on the design, development and installation of decentralised drinking water systems as an alternative to existing water management systems in developing areas. AQUAPOT systems are based on ultrafiltration technology and have been successfully applied in different localities in Ecuador and Mozambique to produce safe drinking water for human consumption. The present paper describes the main actions carried out within the project AQUAPOT over the last 20 years. It describes the main features of the installed plants and the protocol to choose the best location; it also shows the main results achieved within the project, and discusses the lessons learned throughout the years in relation to the operation of the plants as well as the quality of the treated water.

“…Regarding water supply, the numbers provided by the WHO (World Health Organization) are also alarming: 1.1 billion people do not have access to any types of improved drinking source of water [3] and around 50% of them have some health issues related to lack of clean water sources and sanitation systems [4].…”
