摘要 城镇供水和污水处理系统的实际发展是物理、经济和社会环境等多种相互关联因素的结果。人口也是制定发展战略时需要考虑的重要因素。在政策文件中，人口增长常常只是作为采取紧急行动的论据，而很少作为其本身影响改善严重局势机会的因素。开发了一个模型来生成与人口增长相关的城市地区的水管理方案。一个假设是，在城市快速扩张时期，管理规模应该较小。对上世纪肯尼亚维多利亚湖畔的基苏木镇的水和卫生设施的发展进行了一项研究。目的是描述和分析水务部门的实际发展，并预测在人口持续快速增长的情况下可以确定的未来发展。殖民时期城镇的缓慢发展使得城镇能够充分满足所有居民对水的需求。 1963年独立后极快的人口增长与其他因素相互作用，导致居民获得供水和污水处理的情况不断恶化。
Abstract Actual development of water and wastewater systems in towns is an outcome of several interrelated factors such as physical, economic, and social environments. Demography is also an important factor to consider in the formulation of development strategies. Too often in policy papers, population increase only serves as an argument for urgent action, but rarely as a factor in its own right that affects chances of improving a grave situation. A model is developed to generate water management options in urban areas related to population growth. A hypothesis is that management should go small in periods when the city expands rapidly. A study is presented of the development of water and sanitation in the town of Kisumu in Kenya on the shore of Lake Victoria during last century. The aim is to describe and analyze actual development in the water sector and to foresee what prospective developments could be identified in light of continued rapid population growth. The slow growth of the town in the colonial period allowed towns to adequately meet the needs of all residents for water. The extremely rapid population growth after Independence in 1963 interacted with other factors to cause a successive deterioration of residents access to water and sewage disposal.
