Impact of Rapid Urbanization on Urban Water Supply: A Case Study of the Accra Metropolitan Area, Ghana


Book Description

Master's Thesis from the year 2016 in the subject Geography / Earth Science - Demographics, Urban Management, Planning, grade: 1.7, University of Stuttgart, course: Master Program Infrastructure Planning (MIP) - Urbanization and urban water supply, language: English, abstract: The vital role played by urbanization in a country’s development cannot be overemphasized. Urbanization ensures cost-effectiveness in the provision of public infrastructure such as water, electricity, roads, healthcare and schools among others in urban areas as a result of the spatial clustering of population and economic activities. Nonetheless, rapid urbanization without corresponding infrastructure provision results in congestion and pressure on existing facilities and presents a plethora of challenges to city managers and utility providers. This study therefore seeks to examine the major impacts of rapid urbanization on urban water supply. To do this, a case study approach was adopted in order to put the study into context and perspective. More specifically, the study takes the city of Accra, Ghana’s rapidly growing economic and political centre, as an empirical case. The study was based on empirical research conducted in selected suburbs within the city of Accra, including a series of structured and semi-structured in-depth interviews with households, representatives of the Accra Metropolitan Assembly (AMA) and the officials of Ghana Water Company Limited (GWCL). Additionally, the assessment of literature, websites and official city and state policy documents played a crucial role. The broad assessment of the abundant literature consulted and the field survey point to the fact that, indeed, the rapid rate of urbanization in Accra has serious impacts on urban water supply including the environment, physical water infrastructure and overall service delivery. Frequent bursts of pipe lines due to unplanned developments, high incidence of water theft, frequent service interruption due to high water demand and undermined water quality as a result of poor sanitation management are some of the major impacts. Based on the key findings the study proposes relevant policy measures that could help alleviate the negative impacts. These include the need to promote decentralized development in the country; effective planning, regulation and control of development; rehabilitation and expansion of existing water infrastructure in the city; and monitoring and clamping down on water theft in the city among others. The overarching goal of this study is to provide valuable insights into the formulation and implementation of holistic urban policy on water infrastructure towards sustainability and realisation of urban efficiency.







Water and Sanitation in the World's Cities


Book Description

'This is surely the most impressive and important publication to come out of the UN system for many years.' Peter Adamson, founder, New Internationalist, and author and researcher of UNICEF's The State of the World's Children from 1980 to 1995 The world's governments agreed at the Millennium Summit to halve, by 2015, the number of people who lack access to safe water. With rapidly growing urban populations the challenge is immense. Water and Sanitation in the World's Cities is a comprehensive and authoritative assessment of the problems and how they can be addressed. This influential publication by the United Nations Human Settlements Programme (UN-HABITAT) sets out in detail the scale of inadequate provision of water and sanitation. It describes the impacts on health and economic performance, showing the potential gains of remedial action; it analyses the proximate and underlying causes of poor provision and identifies information gaps affecting resource allocation; it outlines the consequences of further deterioration; and it explains how resources and institutional capacities - public, private and community - can be used to deliver proper services through integrated water resource management.

Tapping the Market


Book Description

This book examines the challenge of reform of the urban water supply sector in developing countries, based on case studies of state-owned water companies in Ghana, India, Sri Lanka and Zimbabwe. The growing public private partnership for urban water supply is analyzed, focussing on the concession contract model. The implications for meeting the water needs of the urban poor, for the regulatory role of the state and for state capacity building are also discussed.




Water Supply and Sanitation in Ghana


Book Description

The African Ministers' Council on Water (AMCOW) commissioned the production of a second round of Country Status Overviews (CSOs) to better understands what underpins progress in water supply and sanitation (WSS) and what its member governments can do to accelerate that progress across countries in Sub-Saharan Africa (SSA). AMCOW delegated this task to the World Bank's Water and Sanitation Program and the African Development Bank who are implementing it in close partnership with United Nations Children's Fund (UNICEF) and World Health Organization (WHO) in over 30 countries across SSA. This second CSO report has been produced in collaboration with the Government of Ghana and other stakeholders during 2009-10. The analysis aims to help countries assess their own service delivery pathways for turning finance into water supply and sanitation services in each of four subsectors: rural and urban water supply, and rural and urban sanitation and hygiene. The second CSO analysis has three main components: a review of past coverage; a costing model to assess the adequacy of future investments; and a scorecard which allows diagnosis of particular bottlenecks along the service delivery pathway. The second CSO's contribution is to answer not only whether past trends and future finance are sufficient to meet sector targets, but what specific issues need to be addressed to ensure finance is effectively turned into accelerated coverage in water supply and sanitation. In this spirit, specific priority actions have been identified through consultation. A synthesis report, available separately, presents best practice and shared learning to help realize these priority actions.




Introduction to Urban Water Distribution


Book Description

Focusing primarily on understanding the steady-state hydraulics that form the basis of hydraulic design and computer modelling applied in water distribution, Introduction to Urban Water Distribution elaborates the general principles and practices of water distribution in a straightforward way. The workshop problems and design exercise develop a temporal and spatial perception of the main hydraulic parameters in the system for given layout and demand scenarios. Furthermore, the book contains a detailed discussion of water demand, which is a fundamental element of any network analysis, and principles of network construction, operation, and maintenance. The attached CD contains all spreadsheet applications mentioned in the text, and the network model used in the design exercise. Written in a manner that is easily understood by those who know little about the subject, this introductory text will also benefit experts dealing with advanced problems who wish to refresh their knowledge.




Progress on Sanitation and Drinking Water : 2015 Update and MDG Assessment


Book Description

Despite significant progress in water and sanitation much still remains to be done. This report shows how the world has changed since 1990. It provides an assessment of progress towards the MDG target and insight into the remaining challenges. Section A provides an overview of progress against the parameters specified in the MDG target for water and sanitation in both urban and rural areas. It presents data for the world as a whole and compares progress across regions. The report goes on to examine trends over the MDG period by region and by level of service. It pays particular attention to the numbers of people who have gained the highest level of service in drinking water supply - piped water on premises - and those with no service at all who use surface water for drinking and practice open defecation. In order to understand the nature of progress it is important to look carefully at the way improvements in water and sanitation have benefited different socioeconomic groups. This report sheds light on equality gaps between urban and rural dwellers and between the richest and poorest segments of the population. It presents several new ways to visualize progress on extending service to the poor designed to reveal the nature of inequalities and give the reader insight into the great challenge that still exists in ensuring that progress reaches everyone. The JMP was established in 1990 and is celebrating its Jubilee Year in 2015. Section B provides a retrospective analysis of the evolution of water sanitation and hygiene monitoring over the past 25 years.
