Among the major water supply problems in developing countries are the lack of qualified manpower, inadequate management, and limited financial resources, Trained personnel is not only deficient in many of the water agencies, but also in ministries, health agencies, community organizations and labour categories of all kinds. Operation and maintenance, quality control and revenue collection leave much to be desired. The scarce resources are barely or not at all sufficient to scope with the day to day problems, let alone with investments for the future,These situations differ considerably from region to region. Several countriesmay have manpower available but lace finance. Others may have ample funds, but have a shortage of trained people. Many have neither of them. Management problems occur almost everywhere. Each of the countries has its own options and constraints for future developments. In many developing countries there is also a serious scarcity of water resources. In these countries the introduction of water reuse practices would be an obvious option. The policies and the choice of technologies however, should be seen in the light of these countries overriding problems. Indeed, the reuse of water for human consumption should be avoided where possible, just as much as the use of troated sewage for crops to be eaten raw. But there is ample scope for the promotion of other water reuse practices, especially in more developed areas.The International Drinking Water Supply and Sanitation Decade (1981–1990)appears to be the right context for cooperatively studying the feasibility and research into options of yet another resource for future use. 相似文献

Material flow analysis was applied to model different scenarios which help better identify and quantify water supply and wastewater pollution problems in the city of Kumasi, Ghana. Results show that despite a relative abundance of water resources in the surrounding area of the city, drinking water consumption will remain at a low level (from 49 ± 4 l/cap/day in 2006 to 59 ± 5 l/cap/day in 2015). Changing sanitation practices to using more flush toilets will require significantly more water if these toilets are to be used adequately. The water–nutrient balance shows that total nitrogen (N) and phosphorus (P) outputs of the modelled area are 10 times higher than system inputs, most of this being attributed to human wastes from sanitation. A number of possible measures to reduce nutrient flows into water bodies were identified and quantified, showing the usefulness of the applied model in providing estimates for municipal decision-makers. 相似文献

Intermittent water supply systems are characterised by schedules that subject water consumers to less than 24 hours a day or less than 7 days of water supply a week. Causes and problems of water supply intermittency and their management options are generally discussed in isolation. This obscures challenges involved in minimising intermittency problems. Through reviewing of the literature relevant to intermittency causal factors, problems and their solution options, this paper finds that the interplay between political, social, economic, natural and technical factors, as they contribute to the development and sustenance of water supply intermittency, calls for interdisciplinary approaches to resolving the problems. These approaches will facilitate understanding of the challenges and development of integrated sustainable interventions. Where water resources are abundant, these interventions should involve conversion from intermittent to continuous supply as the ultimate option to handling supply intermittency problems. For this, development of systematic conversion procedures is recommended. 相似文献
