Beijing is located in a semiarid region, and water shortage is a common problem in the city. Along with the rapid increase in water demand, due to fast socioeconomic development and an increase in population, a shortage of water resources and a deterioration of the water environment have become obstacles to sustainable socioeconomic development in Beijing. In the long run, sustainable water resources management, water conservation, and completion of the south to north water diversion project will solve the problem. This paper introduces the water resources situation in Beijing; analyzes future water demand; and discusses the actions of water saving, nontraditional water resources exploitation, wetland construction, and water environment protection. The paper also explains the importance of the south to north water diversion project and the general layout of the water supply strategy, water distribution system, and methods to efficiently use the diverted water in Beijing.Key words: water resources, water supply, water saving, water recycling, water diversion.

Semi Arid Region

Located in a semi-arid region in the south and east of the country, the Moroccan oases are characterized by severe aridity and scarcity of water resources. However, the ancestral populations have shown a major form of adaptation to aridity constraints through the development of knowledge and heuristic expertise on a traditional water supply system called ‘Khettara’. Currently, the effects of climate change on the one hand and the deep social, cultural and economic transformations on the other, have caused the productivity of traditional agriculture to no longer match population needs with progressive vanishing of Khettara as its consequence. A diagnostic study of the situation of oases conducted in the south of Morocco makes it possible to address the socio-economic, environmental and cultural aspects by developing and using a specific methodology to assess fragile ecosystems (DPSIR: Driving Force-Pressure-State-Impact-Response). The main aim of the present work is to provide a methodology allowing the formulation of the required knowledge for the mobilization of traditional water resources techniques such as Khettaras, in order to maintain the national heritage of oases. The modeling formalism of UML (Unified Modeling Language) is borrowed from information technology for the purpose of standardization. The developed methodology enhances these traditional water supply systems by combining traditional and modern techniques to increase their performance in terms of reduced maintenance costs and increased productivity. The developed methodology has been applied to a real case characterized by extreme aridity.

Groundwater Level Prediction

Water resources managers can benefit from accurate prediction of the availability of groundwater. Ground water is a major source of water in Turkey for irrigation, water supply and industrial uses. The ground water level fluctuations depend on several factors such as rainfall, temperature, pumping etc. In this study, Hatay Amik Plain, Kumlu region was evaluated using Autoregressive (AR) and Support Vektor Machines (SVMs) methods. The monthly groundwater level was used the previous years data belonging to the Kumlu region.

Recycling System

Water demand is increasing, but thus water resources are increasingly threatened due to the increasing use and pollution of the environment, therefore there is a need for long-term strategies regarding water use in order to maintain the sustainability of water resources in Indonesia, especially in the DKI region This study shows the effective steps in the efficient use of the water in the Astra South Jakarta property area, by reengineering the water recycling system, which uses the Overall Equipment Effectiveness (OEE) method. The results of this design have been able to increase engine effectiveness from 51.9% to 88.9% and water recycling productivity up 168% (production from 20m 20 to 54m³ per day), so that can reduce PDAM water supply 16.6% (water requirement before the system re design are an average of 4,088.2 m³ per month, after redesigning the system 3,407 m³ per month). The redesign of the system is also able to prepare water reserves that can supply water for the development of Astra properties in the area of around 20m per day. At DKI Profession level, the design of the reengineering can contribute to the DKI Jaya, the water supply of 0.00002% per day and can reduce the utilization of ground water because the water needs in Astra have been fulfilled.
