Abstract:

The environmentally and economically sustainable provision of safe drinking water remains one of the most significant public health challenges facing society. It is particularly difficult in small municipalities that lack the human and financial resources to maintain complex and/or expensive water treatment systems, especially in regions where the water is naturally contaminated with toxic substances such as arsenic. This paper analyses two municipalities (Kanjiža and Senta) in northern Serbia with groundwater arsenic concentrations significantly higher than the 10 µg/L maximum allowable conce

Non-revenue Water (NRW) is an important component of commercial water system management. NRW is the result of pipelines leakage, improper, illegal service connections and theft water. NRW contributes system loss that is a buzzword. Actually, NRW is uncounted water that has been produced but it is confirmed to be lost before it consumes the customer. This matter agitates for all concern and specially it affects the whole economy.

Abstract:

Lack of water results in a reduction in photosynthesis in plants and crops. Plants are significantly affected when the soil water level is depleted thereby resulting in low production in the agricultural sector which can lead to a reduction in food supply. This problem makes water supply and management highly necessary for plants to grow effectively. Over the past century, the rate at which water usage has increased globally has increased at a rate higher than that of population growth. Particularly in dry regions, an increasing number of regions are now using more water than they can sustaina

Water supply systems frequently present high-energy consumption, which correspond to the major expenses of these systems. Energy costs are a function of real consumption and the daily energy tariff. This paper presents a model of optimization to guarantee the delivery of enough water to populations, for each day. Although, in order to achieve that, energy for pumping is needed, representing the main cost for the companies that operate the systems. The model, developed in MATLAB®, provides the best solution to take in each time step. Simultaneously the population water consumption must be guara

The economic crisis that has hit almost all parts of the world has forced everyone to rethink their own economic arrangements. One thing to consider is the use of hot water. Not by eliminating it, but by looking for other alternatives to produce hot water. The heat-generating system that is widely used by the community is the electric water heater. On the one hand, this system works effectively because it can produce hot water with a maximum temperature of 750C. But on the other hand this system is not economical, because the electricity costs are very large. An alternative that can be given i

Abstract:

This study is based on the design of a portable automatic water level control switch that is capable of switching on the pump when the water level in the overhead tank goes low and switches it off as soon as the water level reaches a pre-determined level to prevent dry-run of the pump in case the level in the underground tank goes below the suction level. The water in the tank is measured by the conductive probes and displaced via the LED indicators. At maximum-set capacity the pump is de-energized to automatically switch off, thereby stopping the inflow of water into the tank. The design appr

Abstract:

Modern organized societies require robust infrastructures, among which hydraulic projects, such as water supply and drainage systems, are most important, particularly in water-scarce areas. Athens is a unique example because it is a big city (population 3.7 million) located in a very dry area. In order to support the development of the city, large hydraulic projects had to be constructed during its history and, as a result, Athens currently has one of the largest water supply systems in the world. Could Athenians choose smaller scale infrastructures instead? Analyzing social, technical and eco

Abstract:

Developed and crafted in Madagascar, the Raseta pump is a novel hydraulic ram (hydram) pump using a springs system. It operates differently from other pumps by the exclusive use of water energy due to the water hammer phenomenon induced by the sudden stop of the water flow. The present study initiates the investigation of the environmental impacts of this new type of hydram pump through a life cycle analysis using OpenLCA 1.8. It was found that, when operating in a small-scale water pumping system, the choice of the pump supply pipe material has small differences of environmental impacts, whet

Abstract:

Non-potable urban water reuse is Japan's main water reuse practice, which includes water for environmental uses, in-stream flow augmentation, toilet flushing, and industrial reuse. On-site water recycling systems reclaim wastewater on site as well as harvest rainwater in one or more large buildings and distributing the reclaimed water within the buildings for non-potable reuse. Based on our survey conducted in 1999 on current status of on-site water recycling systems in 23 wards of the Tokyo Metropolitan Government District, the following findings are reported in this paper: (1) on the average

Abstract Desalinated water is becoming a significant resource in many countries. With limited water supply, several high-demand sites located far from the desalination plant and an efficient and cost-effective transmission and storage network have become critical. In many areas, desalinated water is not delivered efficiently through a pipeline and storage tank system capable of providing safe and cost-effective coverage to a wide range of demand sites. In addition, due to the limitation of transmission and storage distribution, many desalination plants are unable to achieve full production cap

The island's water is mainly used for drinking and for sanitary needs of the population and tourists, and only a small part is used in industrial production. Tourism causes high seasonal water needs which can hardly be met with the existing water supply system. Agriculture has long tradition on the island. Toda

Efficient use of irrigation water is crucial to face the uncertain trend of a declining water resource. Ensuring a supply of water that matches crop evapotranspiration (<i>ETc</i>) while optimizing soil moisture is challenging. This study aimed to come up with a model of an irrigation system that can supply water immediately to meet <i>ETc</i> without using electricity. To test the proposed water balance model a trial was established in water lettuces. The system consisted of 15 pots connected in serial using water pipes and hoses through the bottoms of the pots.
