The “Kljuc” groundwater source in the alluvion of the Velika Morava River provides water supply for the City of Pozarevac at a rate of roughly 220 l/s. Groundwater is abstracted by means of tube wells which are up to 20 m deep. Since 2000, nitrate concentrations in water at this source had a continuous upward trend. Constant intrusion of groundwater with nitrate concentrations higher than 100 mg/l, mainly from suburbs which have no access to utility services, led to a temporary shutdown of the source in 2006. However, following the construction and commissioning of an infiltration-based protection system, a hydraulic barrier was created which allowed the water source to continue to service the public water supply system. This paper presents the performance of this system during the period from September 2006 to March 2007.

Singapore's water resources system is a strong illustration of the value of an integrated water resources management in urban enviroments. Today, urban water resources planning and environmental engineering are essential partners in the planning of tomorrow's urban environments - and not just as passive projects unnoticed by the public. In Singapore we can see the specific evolution from the separate development of water catchments and the control of monsoon flooding to the integrated water management strategy as exemplified today in the Marina Barrage. The multi-purpose project boosts Singapore's water supply by creating its first reservoir in the city, helps flood control and enhances the living environment of the city. Marina Barrage presented many interesting challenges in the development of a project whose impact was designed to far transcend the normal functional aspect of a large public works project. This paper will present the many potential public uses that were considered in the planning for the final facility. The motivation is that the 3P (people, public and private) sectors play an important part in sustaining water resources. Instead of designing the Marina Barrage as a conventional functional facility accessible only to operational staff, the project breaks new ground in taking an unconventional design approach. The facility was designed as an open facility to engage and inspire the public to care for water. Features for public education, lifestyle attraction, eating experiences, options for families to relax, play areas for children, attractions for overseas visitors, spaces for dedicated conferences and many more were considered. A multi-functional team of interior designers, landscape architects, researchers, art specialists, lighting specialists, environmentalists, etc was assembled and met continually as the design evolved. These evolving goals had to be integrated into the overall functional characteristics of the barrage. The resulting project is a world-class example of how a project initially conceived for water resources functional purpose can evolve not just into an iconic structure but one whose multi-functional capabilities have attracted huge attention from tourists and the people of Singapore. This is evidenced by more than 250,000 people visiting the facility in its first 6 months of operations, and the many families who spend relaxing time enjoying the various spaces at the Barrage. The evolution of the Marina Barrage in design and operation can act as a lesson for other cities considering similar large flood control or water supply projects. The success of the Marina Barrage's 3P mission indicates how for a relatively little increase in cost these facilities can play a major role in enhancing urban lifestyle in sustainable cities.

Zahedan, with a population of about 500,000, lies in the most arid area of Eastern Iran, close to Pakistan border. This city has shown the highest rate of population grown among the big cities of the country in the last two decades. Groundwater is the sole water source for the city. It is provided from an aquifer with an area of 120 km2. Groundwater  pollution and problems in water supply appear to be the main factors preventing the sustainable economic development of the city . The quality of groundwater has deteriorated sharply since last several years owing to the following main factors. (1) Groundwater pumping has exceeded natural recharge in the Zahedan watershed since 1980, and groundwater level in the city has been declining because of low yearly rainfall (Precipitation in the Zahedan watershed averages 95 mm per year, mainly in the winter). (2) The city population is growing fast, especially after 1980, and the aquifer pollution by human activities is serious. (3) Uncontrolled and unplanned development of the city in the western part over the aquifer that is providing fresh water has led to the problem of overexploitation and further groundwater pollution . At present, a massive federal project for the construction of 191 km long pipeline is in progress. It will fulfill the public demand of drinking water by bringing water from the Chahnimah Reservoir that is fed by the Hirmand River.

With the development of cities in a more integrated and innovative management for urban sectors, the smart cities emerge, usually incorporating this evolution using the Information and Communication Technology (ICT), necessitating investments in technology and innovation in the public policies. In light of this context, the purpose of this paper was to carry out the diagnosis of the city of Maringa concerning innovation and the use of ICT in the potable water public supply sector. It was conducted interviews with the responsible for the concessionaire of the water supply in Maringa (SANEPAR), and also document evaluations. The results attest to the development of a project elaborated by SANEPAR in partnership with Parana Meteorologic System (SIMEPAR), with the intention of a more intelligent water supply system, that allows the prediction of possible floods in the water catchment plant by heavy rainfall. Thus, it can be concluded that there is the intention of implementing smart technologies, beginning with the protection to the catchment of the water, that can be extended to the operation of the whole water supply system of the municipality of Maringa.

The total population Bontang in 2014 is around 187,346 peoples. With the level of domestic water demand of 110 liters /person/day, the water needs of the city for at least Bontang 238.52 liters/sec. Currently for the needs of the community water supply received from the local water company with a capacity of 80 liters/sec, and It will be developed further to 250 liters/second in 2015. There are two big industries that need huge of water, namely LNG and Fertilizers Factory.  Factory of East Kalimantan (PKT) need additional water supply around 1000 m3/h or (166.67 liters/sec) with the specifications for the Water Industry   and 200 m3/h will be used to supply the needs of water for 21 818 inhabitants. Bontang city water source can be derived from groundwater, rivers, and rain water storage (reservoirs of water). In recent decades Bontang relied upon groundwater for water supply industry and some communities, the rest use river water and rain water tandah. With a very heavy rainfall ( 2500 mm / year), then the making of ponds in large quantities can help to reserve water in the future. For the purposes of future water supplies, it would require an asessment of all potential water resources utilization and planning for the use of adapted to the urban development plan. Water recycling of domestic waste is also a potential source of fresh water in the future, especially for industrial use. The drainage system needs to be directed at a large holding pond located in a low area, before going into the sea. The rain that fell in the city drained and collected would be of potential if utilized. In short-term utilization of water of the Bontang river is very of potential, given its location in the city center and is one of the many watersheds in Bontang, causing floods in the rainy season. Control and management of water is needed to support the use of river water.Keywords: Water resources, Water Demand, Water Supply, and Water Balance

The existing groundwater source for the public water supply of Becej City in Serbia is tapping groundwater from three water-bearing horizons over 15 wells with a summary capacity over 100 l/s. It is one of the characteristics of sources that several water-bearing layers are most frequently tapped simultaneously by wells. Two layers are tapped simultaneously by 12 wells; all three layers are tapped by ten wells, while one water-bearing layer is tapped by only three wells. The groundwater table at the source was recorded for a period of 30 years. In the conducted hydrodynamic analysis of the groundwater regime, it was concluded that in the mentioned period, a relatively low fall of the water table occurred, far lower than the previously predicted values. The results of a simulation of the exploitation regime of both the town and surrounding sources are presented in this paper for a period of more than two and a half years and the results of the identification of the basic hydrogeological parameters of the tapped water-bearing layers are presented in this paper. In addition, a balance for each element in the water-bearing layers exploited as sources of tapped water for the town are presented.

The artificially recharged groundwater source Mediana provides water supply to the City of Niš. It is situated on some 250 ha of land in an alluvial valley. In the early 1990s, the source sustained heavy pollution by organic pollutants from nearby electronics industry, and somewhat less extensive pollution by nitrites from a neighbouring settlement. The capacity of the source decreased from 270 l/s to 150 l/s. The pollutants were flushed and a permanent protection system was put in place. Following revitalization, this groundwater source was upgraded to the current capacity of 500–600 l/s. Monitoring of the groundwater source during the period from 1996 to 2006 revealed no functional interferences, confirmed that the source delivers the required water quality, and indicated that significant self-purification processes are taking place in the aquifer.

Known as one of the ten most important advances on Public Health in the 20th century, fluoridation of public water supply is a measure of wide population coverage, which is effective on caries control. The city of Araçatuba, in the Northwest region of the São Paulo state, Brazil, started public water supply fluoridation in 1972 and, based on the average annual highest temperature, has kept the fluoride concentration between 0.6 to 0.8 mgF/L. The purpose of this study was to analyze monthly the fluoride concentration in public water supply in the city of Araçatuba during 72 months. Water samples were collected monthly on weekdays, directly from the water distribution network, on pre-established locations and analyzed in duplicate between November 2004 and October 2010 at the Research Laboratory of the Nucleus for Public Health (NEPESCO) of the Public Health Graduate Program from Araçatuba Dental School/UNESP, Brazil, using an fluoride-specific electrode connected to an ion analyzer. From the total of samples (n=591), 67.2% (n=397) presented fluoride concentration between 0.6 and 0.8 mgF/L; 20.6% (n=122) below 0.6 mgF/L; 11.5% (n=68) between 0.8 and 1.2 mgF/L and 0.7% (n=4) above 1.2 mgF/L. Most samples showed fluoride levels within the recommended parameters. Minimal variation was observed among the analyzed collection locations, showing that the city has been able to control the fluoride levels in the public water supply and reinforcing the importance of surveillance and constant monitoring to assure the quality of the water delivered to the population.

This article examines the suitability of water supply installations in residential buildings for the pressure conditions of the main water network, and evaluates the energy saving possibilities associated with pumping water into homes. It assesses the situation and the options for renovation in a sample of 151 buildings in the city of Zaragoza (Spain), estimating the savings in electric power and the possible financial returns that could be obtained. The results show that in half the buildings, the installations are inadequate and lead to inefficient energy use, which could be avoided by renovation. However, they also show that in many cases, this type of retrofitting would not be profitable for the building owners, meaning that technically viable solutions may not necessarily be financially viable. To mitigate or avoid the energy inefficiency in question, the public sector could step in by informing and financing support for building owners and regulating in the areas of town planning and construction.

The issue of rationalizing water consumption and preserving it for future generations is one of the most important indicators of sustainable development referred to in the Agenda 21. This study aims to assess the sustainability of water resources for the city of Erbil in terms of quantity and quality. In this study, the amount of water available in the existing water sources was evaluated and compared with the volume of water demand. The reliability of water sources, especially groundwater, in the selected area was evaluated and confirmed. The study also focused on the management of groundwater by the concerned authorities and the identification of factors that help to develop the sustainability of these sources. The problems facing the management of groundwater and the proposed solutions to solve these problems were also identified. Due to the rapid growth of the populations and lack of both water demand and water supply system, Erbil City required a fundamental evaluation of water supply systems and good planning for future. However, in this study, the assessment was conducted based on the existing data and the accurate archived documents as well. As a result, the study concluded that there have been a lot of problems that should be taken into consideration in order to provide good managing of the groundwater system. It was also observed that there was slightly higher depletion in groundwater table due to poor supplying. This study can be used as a fundamental reference for future investigations especially for those areas having the same problems in sustainable management of the subsurface basins.
