This paper highlights the importance of considering ecological sustainability issues in any town's infrastructure plans and investments. It reviews the sustainable impact of different developing countries such as water supply, drainage, electricity, tree plantation, transportation and planning in urban and town infrastructure as a case study, both to enhance economic growth and to contribute to poverty reduction, and what this implies for developing countries. It highlights the lack of attention given to ecological issues and the dangers of assuming that the resources will be available to support it and those prices for fresh water, fossil fuels and food will not rise. It also points to large ecological footprint and its heavy dependence on non- renewable resources, especially solid waste management- which means that turning waste into wealth by deriving income from solid waste, every waste price rise transfers money from the economy to national and global financial circuits. Housing lower-income groups in conventional housing with no attention to a more compact, less automobile-dependent city form exposes them to high water and energy costs. The paper ends by pointing to the advantages for the town of developing and for lower-income groups of including ecological issues, and outlines the possibilities for doingthe occupational health hazards should be minimised by adhering to safety precautions.
