Abstract The provision of clean water for the community is not optimal, so that the distribution of water is not evenly distributed. The distribution network of PDAM Tirta Jati serves Taman Tukmudal Indah Housing, Sumber District, which is supplied from Cigusti springs with a gravity drainage system, currently reaching 1,037 units of house connections. Geographic Information Systems visualize spatial data related to positions on the earth’s surface. Analysis of Clean Water Service Capacity in the discussion of clean water quality that has been tested in the Bandung Institute of Technology laboratory. The samples tested for analysis showed that the clean air quality met the quality standards. The standard of clean water needs is 60 liters/person/day. Continuity shows that the clean air pressure is not in accordance with the minimum standards that have been determined because most of the air pressure is still low. The lowest air pressure = 1.00 meters, and the highest = 50 meters, the lowest average air pressure is at 22:00 and the highest is at 09:00. The minimum air pressure that must be met is 1.0 atm. This pattern is expected to maintain the quality, quantity, and continuity of clean water services.

Abstract Proper understanding of reservoir producing mechanism forms a backbone for optimal fluid recovery in any reservoir. Such an understanding is usually fostered by a detailed petrophysical evaluation, structural interpretation, geological description and modelling as well as production performance assessment prior to history matching and reservoir simulation. In this study, gravity drainage mechanism was identified as the primary force for production in reservoir X located in Niger Delta province and this required proper model calibration using variation of vertical anisotropic ratio based on identified facies as against a single value method which does not capture heterogeneity properly. Using structural maps generated from interpretation of seismic data, and other petrophysical parameters from available well logs and core data such as porosity, permeability and facies description based on environment of deposition, a geological model capturing the structural dips, facies distribution and well locations was built. Dynamic modeling was conducted on the base case model and also on the low and high case conceptual models to capture different structural dips of the reservoir. The result from history matching of the base case model reveals that variation of vertical anisotropic ratio (i.e. kv/kh) based on identified facies across the system is more effective in capturing heterogeneity than using a deterministic value that is more popular. In addition, gas segregated fastest in the high case model with the steepest dip compared to the base and low case models. An improved dynamic model saturation match was achieved in line with the geological description and the observed reservoir performance. Quick wins scenarios were identified and this led to an additional reserve yield of over 1MMSTB. Therefore, structural control, facies type, reservoir thickness and nature of oil volatility are key forces driving the gravity drainage mechanism.

Two main building Kalimantan Institute of Technology was established on an area of 3500 m2 on October 6, 2014 which serves as the infrastructure for teaching and learning activities of students. The rapid increase in the number of students each year results in an increase in the number of buildings as facilities for teaching and learning. This is the background for the development of the Kalimantan Institute of Technology area by adding five more lecture buildings to support teaching and learning activities for 3500 students. The expansion area for five more lecture buildings is currently under construction in the area of ​​the Faculty of Mathematics and Natural Sciences. The function of the land area has been change due to building construction resulted in an increase in runoff discharge. This condition certainly affects the region if not handled properly. Increased runoff discharge will affect inundation or flooding in the area if it is not equipped with a drainage system as needed. This research is one alternative solution given. This research is in the form of a study on the implementation of a drainage master plan that aims to obtain drainage dimensions such as drainage width, drainage length and drainage depth by observing runoff due to rainwater using the concept of environmentally friendly drainage. The research obtained from the dimensions of tertiary canals with dimensions of 0.10-0.30 meters, secondary channels 0.30-0.45 meters and primary channels 0.35-0.70 meters with the discharge area of ​​the Faculty of Mathematics and Natural Sciences ITK is 1.18 m3/ sec.

Abstract—Water is an important element that becomes the need of every human being, in the service provider company Clean water control of water usage is still a problem because there is no system that provides information on the use of water on the customer side, especially in the BLUD UPT SPAM Musi Rawas. Customers also find it difficult to see the amount of bills in realtime so that if the billing information has been presented then the customer can adjust the use of the water. This system will use a Waterflow Sensor to read the water flow which will then be converted to Digital data in the form of computer bits that will be processed by Arduino and then sent to the Server to be seen by the Clean Water Service Provider in this case the BLUD UPT SPAM Musi Rawas and customers. Intisari—Air merupakan unsur penting yang menjadi kebutuhan setiap manusia, pada perusahaan penyedia layanan Air bersih kontrol penggunaan air masih menjadi masalah karena belum ada sistem yang menyediakan informasi penggunaan Air pada sisi Pelanggan khususnya di BLUD UPT SPAM Kabupaten Musi Rawas. Pelanggan juga kesulitan untuk melihat jumlah tagihan secara realtime sehingga jika informasi tagihan tersebut sudah tersaji maka pelanggan dapat mengatur penggunaan Airnya. Sistem ini akan menggunakan Waterflow Sensor untuk membaca aliran air yang kemudian akan di konversikan ke data Digital  berupa bit komputer yang akan di proses oleh Arduino kemudian di kirimkan ke Server untuk dapat di lihat oleh Penyedia Jasa Air bersih dalam Hal ini BLUD UPT SPAM Kabupaten Musi Rawas dan Pelanggan.

Clean water supply is a major problem among flood victims during flood events. This article aims to determine the sites of well water sources that can be utilised during floods in the District of Kuala Krai, Kelantan. Field methods and Geographic Information Systems (GIS) were applied in the process of selecting flood victim evacuation centres and wells. The data used were spatial data obtained primarily, namely the well data, evacuation centre data and flood area data. The well and evacuation centre data were obtained by field methods conducted to determine the position of wells using global positioning system tools, and the same for the location of the evacuation centres. Information related to evacuation centres was obtained secondarily from multiple agencies and gathered into GIS as an evacuation centre attribute. The flood area data was also obtained via secondary data and was digitised using the ArcGIS software. The data processing was divided into two stages, namely the first stage of determining the flood victim evacuation centres to be used in this research in a structural manner based on two main criteria which were the extent to which an evacuation centre was affected by the flood and the highest capacity of victims for each district with the greatest impact to the flood affected population. The second stage was to determine the location of wells based on three criteria, namely i) not affected by flood, ii) the closest distance to the selected flood victim evacuation centre and iii) located at different locations. Among the main GIS analyses used were locational analysis, overlay analysis, and proximity analysis. The results showed that four (4) flood evacuation centres had been chosen and matched the criteria set, namely SMK Sultan Yahya Petra 2, SMK Manek Urai Lama, SMK Laloh and SK Kuala Gris. While six (6) wells had been selected as water sources that could be consumed by the flood victims at 4 evacuation centres in helping to provide clean water supply, namely Kg. Keroh 16 (T1), Kg. Batu Mengkebang 10 (T2), Lepan Meranti (T3), Kg. Budi (T4), Kg. Jelawang Tengah 2 (T5) and Kg. Durian Hijau 1 (T6). With the presence of the well water sources that can be used during flood events, clean water supply can be distributed to flood victims at the evacuation centres. Indirectly, this research can reduce the impact of floods in the future, especially in terms of clean water supply even during the hit of a major flood.

Maintaining healthy forests is the major objective for the Forest Service scientists and managers working for the U.S. Department of Agriculture. Air pollution, specifically ozone (O3) and nitrogenous (N) air pollutants, may severely affect the health of forest ecosystems in the western U.S. Thus, the monitoring of air pollution concentration and deposition levels, as well as studies focused on understanding effects mechanisms, are essential for evaluation of risks associated with their presence. Such information is essential for development of proper management strategies for maintaining clean air, clean water, and healthy ecosystems on land managed by the Forest Service. We report on two years of research in the central Sierra Nevada of California, a semi-arid forest at elevations of 1100–2700 m. Information on O3and N air pollutants is obtained from a network of 18 passive samplers. We relate the atmospheric N concentration to N concentrations in streams, shallow soil water, and bulk deposition collectors within the Kings River Experimental Watershed. This watershed also contains an intensive site that is part of a recent Forest Service effort to calculate critical loads for N, sulfur, and acidity to forest ecosystems. The passive sampler design allows for extensive spatial measurements while the watershed experiment provides intensive spatial data for future analysis of ecosystem processes.

A drainage system is one of the most essential facilities in building service engineering. Unfortunately relevant technology used today to analyze it was developed decades ago. This research investigated the case of existing building drainage systems in Taiwan, including our previous studies. The purpose of this paper is the development of a non-destructive testing method of air pressure fluctuation in a stacked building drainage system using field observation and experimental study of stack fluid mechanisms. A portable testing device is developed to execute field testing in existing drainage systems to determine air pressure fluctuation in the stacks of buildings. Meanwhile, the Fourier Transform Process is adopted in this paper to analyze the power spectrum of air pressure fluctuation in a drainage stack and to verify the previous theoretical study. Validation obtained from case-studies can be used to confirm the practicality of this portable and non-destructive testing method. As a result, the proposed testing method can be applied to the diagnosis of existing building drainage systems and improve the design of a drainage system in an existing housing complex.
