Increasing urbanization has resulted in an uneven distribution of population, industries, and water in urban areas; thus, imposing unprecedented pressures on water supplies and water pollution control. These pressures are exacerbated during the periods of drought and climatic uncertainties. The purpose of this paper is to summarize emergence of water reclamation, recycling and reuse as a vital component of sustainable water resources in the context of integrated water resources management in urban and rural areas. Water quality requirements and health and public acceptance issues related to water reuse are also discussed. Reclaimed water is a locally controllable water resource that exists right at the doorstep of the urban environment, where water is needed the most and priced the highest. Closing the water cycle loop not only is technically feasible in agriculture, industries, and municipalities but also makes economic sense. Society no longer has the luxury of using water only once.

State Of Water

The large number of people living together in urban areas requires a comprehensive solutions for issues such as the reasonable allocation and adequate use of natural resources, urban planning, and efficient waste management to meet the city's needs.  One of the main factors influencing the health and comfort of urban residents is the supply of clean water and sewerage systems. Therefore, in order to rationally allocate and use water resources to meet urban needs, and to create a healthy and comfortable living environment for city residents, it is necessary to develop an integrated water resources management plan at the national and basin levels, as well as an integrated water management plan and assessment for city level. In addition to assessing the current state of water management, it is important to identify factors and trends that may further strain water resources to prevent future risks. To address the pressures on water management in Ulaanbaatar and Darkhan, representing Mongolia's urban areas, the City Blueprint Approach, developed by the EU Water   Innovation Partnership and the Dutch Institute of Water Cycle, was used in this study. Currently, this approach is used in about 80 cities in more than 40 countries, it is a relatively new and innovative method among Asian cities. As a result, water management in Ulaanbaatar and Darkhan is hampered by both social, economic, and environmental factors.

Resources Management

Due to continuous population growth and industrialization along with intensive agriculture to meet food demand, good quality water has become rare in most of the basins of India. Up to the last decade, to solve the water related issues in India, water quantity and quality were considered individually; and it was realized that individual consideration of these parameters will not solve the problem for long term. Therefore, at present, a concept of integrated water resources management has been encouraged to manage the water resources and pollution control in the rivers. In the present study, an efficacy of a decision support system (DSS) has been presented for the Yamuna River to augment the good quality of water as environmental flows, which include the hydrology, natural resources, pollution, socio-economics, infrastructural development, etc of the basin. Using the DSS, numbers of possible scenarios were tested and it is revealed that installation of sewage treatment plants (STPs) alone cannot improve the water quality of the river when river is highly intercepted. To ensure the environmental flows in the river, integrated water resources management has become important at micro-watershed level

The aim of this chapter is to look at the integrated water resources management (IWRM)-related institutional shift in governance of water and sanitation in Durban and the extent to which class is considered in providing rural inhabitants with facilities they regard as sub-standard. The key finding is that rural communities remain uncomfortable with nearly 90,000 UD toilets constructed by eThekwini Municipality, despite current efforts being made to relieve them of the most hated chores of emptying vaults when they fill up. In a study conducted in rural areas of Durban through interviews with 70 households and focus group discussions, communities continue to reject UDs on the grounds of lack of equity, proximity to areas with flush toilets, lack of communication, and lack of sustainable institutional mechanisms associated with this project.

Resources Management

Integrated water resources management at the catchment scale, considering the full water cycle as manageable, is a primary approach to improve water use efficiency and promote sustainable water management solutions. To this purpose, advanced modelling tools are required to quantify the physical and economic effects of alternative land management options. This work presents an application of a spatially distributed physically based hydrological model to the Bonis experimental watershed located in the mountain area of Sila Greca (southern Italy). Different infiltration models were tested to better reproduce discharge observations at basin outlet. The model will be used for evaluating different land use/management scenarios, combined with climate change forcing, to quantify the effect of alternative management options on the land-water cycle. This work is part of the INNOMED project (Innovative Options for Integrated Water Resources Management in the Mediterranean) funded by ERA-NET COFUND WATERWORKS 2015 call.

The City

In this study the sustainability of integrated water resources management in Amsterdam has been reviewed using the City Blueprint approach. The City Blueprint® is a set of 24 dedicated indicators divided over eight categories, i.e., water security, water quality, drinking water, sanitation, infrastructure, climate robustness, biodiversity and attractiveness, and governance including public participation. In 2006 the various urban water-related services in Amsterdam were brought under one roof, culminating in the country's first water cycle company called Waternet. Waternet is responsible for surface water (rivers, canals, ditches and lakes), groundwater, stormwater, drinking water supply and waste water treatment. The city's unique water cycle approach has proved highly beneficial. Currently Amsterdam is the best performing city of the 30 cities assessed so far. This can be explained by: (1) a long-term vision and a multi-level water governance approach, (2) integration of water, energy and material flows (e.g., struvite production), (3) the entanglement between urban quality and water management, and (4) the transparent communication to and feed-back from customers, i.e., farmers and citizens. Surface water quality and biodiversity remain future challenges.
