As climate change and increasing population sizes continue to place stress on water resources, communities are increasingly looking to recycled water as a supplementary water source, whether for drinking water, domestic irrigation, industrial or agricultural use. Protecting public health by ensuring the safety of water supplies is a key concern for the water industry and health authorities.

Pucang Gading Housing Complex is an area within the Village Batursari, District of Demak with a population of 2018 as many as 44,257 inhabitants. Raw water service system Mranggen Unit is divided into 5 areas of service (service area Mranggen, Batursari I, Batursari II, Batursari III and Kebon) which utilize raw water source of water treatment plant (IPA Waru) and 8 Wells In a total discharge of 120 liter/second. The number of home connections in Pucang Gading area is currently 3,374 house connections, with a total water usage 14.25 liter/second Water discharges from clean water sources in Pucang Gading region are currently not maximally available to supply water to Pucang Gading service area. In this research will know the problems and readiness that exist by looking from the achievement of Medium Term Development Plan of Demak Regency Year 2016-2021. This research uses SWOT analysis method that is internal and external factors. The selection of raw water sources for drinking water should pay attention to aspects of quality, quantity and continuity. Demak Regency has the potential of surface water either river/ reservoir/dam. The problems and challenges of drinking water supply include issues of safe access to water supply, and regulation of groundwater utilization for the community.

Affecting Factors

In order to effectively control pollution of sources of drinking water, improve the environmental quality of drinking water and guarantee the sanitation of drinking water, it is very important to assess water source quality. Main factors of drinking water were identified. Then principal component analysis was used to establish assessment model of drinking water, which could ensure that under the condition that the primitive data information was in the smallest loss, a small number of variables were used to replace the integrated multi-dimensional variables to simplify the data structure. The weightings of principal component were determinated as theirs pollution ratios. This paper was based on the theoretical study of principal component analysis, used the monitoring data on water quality of the main water resources in 2013 to evaluate and analyze the water quality of water resources. Analysis content included the main affecting factors, cause of pollution and the degree of pollution.The resulted showed that: the main affecting factors on water quality of Fo Si water source was CODMn, TP, fluoride.

Water is increasingly taking center stage when it comes to coping with climate change. Especially in urban areas, negative consequences from heavy rainfall events and prolonged dry periods are rising worldwide. In the past, the various tasks of urban water management were performed by different departments that often did not cooperate with each other (water supply, wastewater disposal, green space irrigation, etc.), as the required water supply was not a question of available water volumes. This is already changing with climate change, in some cases even dramatically. More and more, it is necessary to consider how to distribute available water resources in urban areas, especially during dry periods, since wastewater treatment is also becoming more complex and costly. In the future, urban water management will examine water use in terms of its various objectives, and will need to provide alternative water resources for these different purposes (groundwater, river water, storm water, treated wastewater, etc.). The necessary technological interconnection requires intelligent digital systems. Furthermore, the water industry must also play its role in global CO2 reduction and make its procedural treatment processes more efficient; this will also only succeed with adequate digital systems. Although digitization has experienced an enormous surge in development over the last five years and numerous solutions are available to address the challenges described previously, there is still a large gap between the scope of offerings and their implementation. Researchers at Hof University of Applied Sciences have investigated the reasons for this imbalance as part of WaterExe4.0, the first meta-study on digitization in the German-speaking water industry, funded by the German Federal Ministry of Education and Research. Only 11% of roughly 700 identified products, projects and studies relate to real applications. For example, the surveyed experts of the water sector stated that everyday problems are considered too little or hardly at all in new solutions, which greatly overburdens users. Furthermore, they see no adequate possibility for a systematic analysis of new ideas to identify significant obstacles and to find the best way to start and implement a digitization project. The results from four methodologically different sub-surveys (literature and market research, survey, expert interviews and workshops) provide a reliable overview of the current situation in the German-speaking water industry and its expectations for the future. The results are also transferable to other countries.

Drinking Water Resources

In 2004, the Ontario Ministry of the Environment proposed the 'Drinking water source protection act' which stipulated that, in the development of water protection plans, significant direct threats to source watersheds are to be identified. Examination of the major risk factors threatening water resources proved there are insufficient scientific data available to regulators to accomplish this task. Research showed E.coli O157:H7, Salmonella, Giardia lamblia, and Cryptosporidium parvum, and the sources of these pathogens in the environment are, qualitatively, significant threats to water resources. However, a quantitative characterization of significance depends of the failure probabilities of pathogen sources. Using the Ontario Spills Action Centre data, the occurrence of failure was found to have a high non-zero probability. However, considerable uncertainties revealed in these data suggest that a better understanding of failure is critical to accurately characterize significant threats to drinking water resources.

Integrated Water Management

Freshwater water resources are not inexhaustible [1]. In recent decades, more and more facts point to this statement from the European Charter for Water. Uncontrolled drinking water interventions, losses in water supply and climate change indicate the problem of sufficient quantities of drinking water [2]. Looking at this problem, it is hard to believe that new quantities of drinking water can be produced. The model of integrated water management has been increasingly used in recent years. The application of new technologies in water supply creates conditions for the controlled management of water intakes and losses in water supply. Each water sapply system needs to develop its own model for integrated water management.
