Management of Water Drainage Systems

Rapid urbanization and the growing world population significantly deteriorates the drainage system day by day. By the year 2025, an increase of 2.6 billion from the projected world population is expected and more than 65% of it will come from the urban areas. As the population increases, the demand for an efficient drainage system also increases. Therefore, without initiative to solve various issues on water management and drainage systems in most parts of the world, it is expected that more than half of the current world population will have no access to effective and efficient ways of wastewater disposal in the future.

In most parts of the world, poor management and maintenance of various drainage systems by the responsible authorities has really affected the efficiency and effectiveness of these systems. Population re-densification in various urban areas and inappropriate use of various components of drainage systems has led to different issues of poor drainage systems such as overflowing manholes and sewers in major cities across the street areas that mainly results in the degradation of the surroundings and eventual destruction of the water flow paths in the cities. The purpose of this book is to offer important insights and provide basic reference about various aspects of drainage systems. This book incorporates all the relevant information that can be used by students and educators (in different fields such as science in civil and construction engineering, environmental planning and management, urban and regional planning, and quantity surveying among other courses), as well as public and private environmental management sector.

This book comprises ten chapters. Chapter 1 provides an overview of the present state of management of drainage systems in most parts of the world. One of the key topic that is mainly discussed in this chapter are the various types of water drainage systems (such as surface drainage system, subsurface drainage system, slope drainage system, and gutter drainage system) and how they relate with other elements of drainage systems. Chapter 2 discusses on matter concerning evaluation of inappropriate discharges on drainage systems. An important topic discussed entirely in this chapter is the assessment of stormwater drainage system. Chapter 3 looks at the management of stormwater drainage system and Chapter 4 explores the irrigation and drainage system....
