Water tank is an important element in water distribution system. The project is studied the characteristics of water tanks and the main objective of it to identify the selection criteria for the water tank. Furthermore, Selection of water tank is a challenge for many individuals and companies. The study is gathers information from many sources such as literature reviews, companies, questionnaire and experts in order to reach to the main important characteristic of water tanks. The selection of water tank depends heavily on the applications. As a result, it found that the best type of storage tanks for sweet water used for human consumption are two types, one of which is polyvinyl chloride to store a quantity of less than five cubic meters and the other is stainless steel tank to store more than five cubic meters. The study found that the best reservoir for irrigation and sewage uses is the carbon steel tank. On the other hand, the study found that the stainless-steel tank is best suited for storage of seawater, which requires a material that can withstand corrosion.

The Maule Mw 8.8 earthquake of 27 February 2010 impacted a number of water and wastewater lifelines. Ground shaking and liquefaction heavily damaged the Essbio water and wastewater systems, particularly in Concepción. Ground shaking destroyed more than 70 elevated water tanks in rural water systems built by the national government. A fire water tank collapsed at the Santiago Airport. There was damage to canals. Despite more than 3,000 repairs to other types of water pipe, the high-density polyethylene pipe used in the Concepción water distribution system was undamaged.

Water Tanks

The use of water tanks as a tool for storing water before being distributed for daily use has become a widely used system today. Among the attempts to develop a water distribution system is optimization in terms of system and operating costs. In this study, four methods of the Runge Kutta method are the Implicit such as Explicit Euler method, Implicit Euler method, Implicit Midpoint Rule, Runge Kutta Fourth-order method are used and compared with the exact solution method. The method will be compared in terms of accuracy and efficiency in solving differential equations based on set parameters for optimum design of water tank. The accuracy and efficiency of each method can be determined based on error graph. At the end of the study, numerical results obtained indicate that the Implicit Midpoint Rule provides greater stability and accuracy for the fixed stepsize given compared to other numerical methods.

AbstractWe conducted a prospective environmental study for Legionella pneumophila in 15 hospitals in Pennsylvania. Hot water tanks, cold water sites, faucets, and show-erheads were surveyed four times over a one-year period. Sixty percent (9/15) of hospitals surveyed were contaminated with L pneumophila. Although contamination could not be linked to a specific municipal water supplier, most of the contaminated supplies came from rivers. Parameters found to be significantly associated with contamination included elevated hot water temperature, vertical configuration of the hot water tank, older tanks, and elevated calcium and magnesium concentrations of the water (P < 0.05). This study suggests that L pneumophila contamination could be predicted based on design of the distribution system, as well as physicochemical characteristics of the water.

The sensorial evaluation of Chenin blanc wine produced with different types of oak wood treatments over time has not been investigated before. The main aim of this study was to assess the sensory profile, using a trained panel, of a South African Chenin blanc wine fermented and matured in old barrels, three types of new oak barrels, two types of oak staves as well as a stainless steel tank over time, which has not been done before. Results indicate mainly separation between the stainless-steel tank/old barrel treatments from the stave and new barrel treatments, with separation between the latter two treatments also being found. More fruity descriptors were used in the stainless-steel tank and old barrel treatments, with oak-related descriptors being used in the stave and new barrel treatments. Separation between among the new barrel and stave treatments were also noted, which was still reflected during bottle maturation. These results indicate that winemakers need to take cognizance of the sensorial differences induced by barrel and stave maturation in white wines and how these evolve over time.

The Impact

High level water tank is a commonly used facility to satisfy water demand for people living in high building, which is also the so-called secondary water supply system (SWSS) in China. Due to lack of maintenance, water quality problem has been frequently reported in the SWSS. In the last few decades, anti-negative pressure facility (ANPF) has emerged as a revolutionary approach for solving the pollution in the SWSS. ANPF makes good use of the municipal pipeline pressure, which is the improvement of traditional water supply. However, most of recent research activities mainly focus on the influence of part of water distribution system (WDS). In this paper, the software of EPANET has been applied in the SWSS calculation and simulation. Besides that, the SWSS with ANPF simulation method is proposed to evaluate the effect of other all nodes pressure in the WDS using hydraulic model. As the cases study, the paper analyzed two WDSs with ANPF. After simulation of the SWSS, the result of WDS, which is smaller, indicates that 6 out of the 9 nodes are affected with ANPF and that of WDS, which is larger, demonstrates that 37 out of the 41 nodes are affected and the affected nodes are focused on the confluent of pipes, especially around the ANPF.

The city of Riobamba captures for human consumption groundwater from melting glaciers, from seven wells in the foothills of the Chimborazo volcano. The objective is determine the percentage of existing microplastics in drinking water distribution system. Sixty two samples were collected, analysed with a cellulose filter and Nile red dye. Then observed in a stereoscope, obtaining presence in 12 samples of the 62 analysed. The results of the analysis show that there is a 19% presence of microplastics.

RC intze water tanks are constructed for storage and suppling of water through a certain height with adequate pressure of water distribution. Many overhead water tanks affected due to certainty like earthquake that can induce large lateral forces. So, there is a necessity to Understand and examine the behavior of intze tank supported on framing in context to different soil types under the seismic forces. This paper evaluates the experimental output of seismic analysis that compares shear and moments at base and also hydrodynamic pressure at wall and base slab for various seismic zone and different type of soil condition at different staging heights.
