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.

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.
