The City

The City of Baltimore, Maryland is one of many US cities faced with challenges related to increasing potable water demands, diminishing fresh water supplies, and aging infrastructure. To address these challenges, the City recently undertook a $7M study to evaluate water supply and treatment alternatives and develop the conceptual design for a new 120 million gallon per day (MGD) water treatment plant. As part of this study, an innovative raw water management tool was constructed to help model source water availability and predicted water quality based on integration of a new and more challenging surface water supply. A rigorous decision-making approach was then used to screen and select appropriate treatment processes. Short-listed treatment strategies were demonstrated through a year-long pilot study, and process design criteria were collected in order to assess capital and operational costs for the full-scale plant. Ultimately the City chose a treatment scheme that includes low-pressure membrane filtration and post-filter GAC adsorption, allowing for consistent finished water quality irrespective of which raw water supply is being used. The conceptual design includes several progressive concepts, which will: 1) alleviate treatment limitations at the City's existing plants by providing additional pre-clarification facilities at the new plant; and 2) take advantage of site conditions to design and operate the submerged membrane system by gravity-induced siphon, saving the City significant capital and operations and maintenance (O&M) costs. Once completed, the new Fullerton Water Filtration Plant (WFP) will be the largest low-pressure membrane plant in North America, and the largest gravity-siphon design in the world.

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.

Experimental studies on chemical and biological pretreatments in membrane filtration processes were carried out to removal manganese contained in raw water and to prevent membrane fouling due to manganese. Two types of the pretreatment reactors, i.e. the fluidised-bed and fixed-bed configurations, were compared in the biological pretreatment experiments. New synthetic media (tubular polypropylene, I.D. 3 mm, O.D. 4 mm, length 5 mm) were used in all three experiments as a manganese-oxidising catalyst. The chemical pretreatment using sodium hypochlorite was effective in manganese removal and controlling membrane fouling; more than 0.8 mg-Cl2/L of chlorine dose was necessary to bring the manganese concentration from 0.4 mg/L in raw water to less than 0.05 mg/L. The biological pretreatment for manganese removal required a long start-up period of more than 40 days. The fixed-bed biological pretreatment was superior in manganese removal and in control of membrane fouling to the fluidised-bed biological pretreatment, which showed wash-out of the attached bacteria resulting in membrane fouling. The linear velocity and the empty-bed retention time required for the treatment of 0.14 mg-Mn/L in the fixed-bed biological pretreatment was 206 m/d and 8.0 minutes, respectively.

This research was initiated from the Pamsimas program targets have not yet been achieved. The causes were limited water sources and raw water supply, sanitation and hygiene behavior, public awareness of the importance of healthy living behavior was low. This study was to describe and analyze the implementation of the Pamsimas program and the supporting/inhibiting factors of the Program. This study used a qualitative approach by selecting key-informants based on a purposive sample technique. The results showed that the the implementation of the Pamsimas Program in Blora Sub-district was not optimal in terms of the variables as a prerequisite for program implementation. These prerequisites tend to be rigid, making it difficult for program implementers in the field to make decisions that are not included in the standard operational procedures (SOP). On the other hand, the individual and community behavior and participatory to the program in supporting the provision of clean water to be positiveBesides that the factors of limited water sources and raw water supply, unsafe sanitation and drinking water remained unsolved. Recommendations of the conclusions of the study are the delegation of authority related to the bureaucratic structure, especially the standard operating procedures (SOP) and the absence / scarcity of raw water sources for clean watethat needs attention to program managers in the field.

Abstract The Semarang City Government prohibits groundwater/deep wells in hotel and apartment buildings because the use of groundwater or deep wells in locations that have experienced subsidence will further aggravate the subsidence. The method used in this research is to purposively select hotel and apartment buildings in Semarang that have received an assessment by the Semarang City Building Expert Team and have received a certificate of serviceability. Furthermore, compare the map of land subsidence in some areas of the city of Semarang with the natural water sources used by the hotel and apartment buildings. The research results showed that from 10 hotel and apartment buildings, there were 7 that used deep wells in zone level II, namely subsidence between 2.1 to 4 cm/year. Meanwhile, 3 other hotel and apartment buildings use water from the Municipal Drinking Water Company of Semarang. The existence of hotel and apartment buildings that use groundwater/deep wells in zone level II will increase and trigger the more significant subsidence in the area, thereby increasing the level of subsidence to level III.

<p>Administratively, Giriasih Rusunawa located at Jalan Griya Asri Permai, Kampung Babakan RT 01 and 02 RW 18 Kampung Babakan, Giriasih Village, Batujajar Sub-District, West Bandung Regency, is in a difficult area for clean water. This study aims to determine the alternative sources of raw water that will be used to meet water needs in Rusunawa. Alternative raw water sources, namely groundwater, surface and rain. The method used by comparing water quality with quality standards. The parameters tested consisted of physical, chemical, and microbiological parameters. The quality monitored is compared to the quality standard based on Government Regulation Number 82 of 2001 Class I concerning Management of Water Quality and Water Pollution Control and PerMenKes No. 492 of 2010 concerning Drinking Water Quality Requirements. Based on the results of analysis of raw water sources, surface water is very possible to be used as a source of water to meet the needs of water in flat from all aspects. Quantity aspect, Saguling Reservoir guarantees continuous availability of raw water, which is 4,000 l / sec and can still be developed up to 5,000 l / sec. Parameters that do not meet quality standards on surface water are: BOD, COD, Phosphate and Manganese. Based on the results of the calculation of water requirements of 3 l / sec to serve the water needs in the flat.</p>
