Über dieses Buch

This book introduces the readers to possible aspects of the rainwater harvesting system against urbanization to plan, design, and implement. Practical applications of rainwater harvesting to supplement potable water, stormwater management, greywater reuse, and managed aquifer recharge are included. Along with conventional practices, advanced technologies for conceptualizing, data collection and processing, test procedures, and design principles are provided to illustrate the theory. This book is a pathway to a water smart city, example problems reflect the solutions for harvested water quantity and/or quality and afterward. Socio-economic assessments are incorporated to explore comprehensive knowledge.

The book covers an interdisciplinary field, thus, suitable for students, researchers, and professionals associated with rainwater harvesting system development and management

Chapter 1. Introduction

Abstract

Urbanization poses increased water demand due to rapid population growth, and also increased impervious lands exaggerate surface runoff and lessen groundwater resources. On the other hand, climate change significantly influences the quantity and quality of rainfall. Worldwide urban water management faces three-dimensional challenges, i.e., potable water shortage, urban floods, or waterlogging and depleting groundwater. This chapter provides an overview of urban hydrology, challenges on urban water management, the glorious history of rainwater harvesting systems, briefly implementation and direction, and their potentiality towards a water smart city.

Chapter 2. Hydrological Aspects

Abstract

The young science ‘hydrology’ reached mathematical analysis for many hydrological principles and involvements of sophisticated instruments and computer techniques. Rainwater harvesting is solely dependent on the ‘hydrological cycle.’ This chapter describes the conventional measurement and computation of precipitation, infiltration, surface runoff, and groundwater movement.

Chapter 3. Rainwater Harvesting System

Abstract

A typical rainwater harvesting system comprises four main components are the catchment, the conveyance, the storage, and the distribution system in the building. This chapter described these components’ details, design, and instalment consideration following the available codes and standards, management strategies, harvested water quality, and economic assessment.

Chapter 4. Stormwater Management

Abstract

Urbanized area is a driver of stormwater flood risk. The rainwater harvesting system has been considered as a part of the stormwater management system. On the other hand, handling overflows from rainwater storage is usually followed by stormwater management requirements. Characterization of urban stormwater runoff, this chapter presents the historical evolution of their management, following current trends, technological advancement, codes, worldwide standards, design and installment consideration, management strategies, and the relevant worked-out examples.

Chapter 5. Greywater Water Reuse

Abstract

Greywater, which results from human activities, i.e., wastewater, has been used once and then considered reuse with treatment. In recent years, significant developments have been recorded worldwide on greywater reuse practices and policies to address the water smart city. Due to the diversity of water use, the quantity and compositions of the generated greywater vary from country to country. This chapter presents the usual greywater reuses, knowledge on the typical quality and quantity of the generated greywater, computation of the greywater footprint, existing codes, integrated uses with either rainwater or/and stormwater, general consideration on design and installation, management strategies, and worked out example problems.

Chapter 6. Groundwater Recharge

Abstract

Groundwater recharge is a part of the hydrologic cycle; water moves downward through drainage or percolation from the water table to the saturated zone. In this process, water enters through an aquifer and encompasses water movement in the vadose zone. Groundwater recharges both naturally (i.e., hydrologic cycle) and artificially, as described in Chap. 2. In the managed aquifer recharge or artificial groundwater recharge, rainwater, or recycled water are considered to be routed into the subsurface. This chapter introduces the managed aquifer recharge, relevant technologies, and worldwide specific regulations and guidelines. Thus, the possibilities and challenges of other technologies are incorporated in rainwater harvesting, stormwater, and greywater reuse to recharge aquifers are discussed in this chapter.

Chapter 7. Economics of Rainwater Harvesting System

Abstract

The economic analysis of a rainwater harvesting system depends on minimizing urban stormwater runoff and consumption of potable water and fuel/energy costs for treatment and distribution. The mode or design consideration of the rainwater harvesting system is demand-based. This chapter describe the required economic assessment of any scheme regarding annual savings due to a rainwater harvesting system for water supply, greywater and urban runoff reduction, and managed aquifer recharge.

Chapter 8. Advanced Technologies in the Water Smart City

Abstract

Rainwater harvesting for the water smart city faces dynamic challenges ranging from land use land cover (LULC) and hydrological cycle alteration. Thus, the planner and designer need advancement in the long term as well as real-time dataset handling. This chapter described the advancements in the hydrologic study, demand-based models on rainwater harvesting systems, automated rainwater treatment, advanced tools for planners and architects, and socio-economic models.
