The water may be supplied to the consumers either- (1) by continuous system or (ii) intermittent system. In the continuous system, water is available to the consumers for all 24 hours a day. Whereas, the intermittent system supplies water only during the peak hours of water demand, which is fixed hours in the morning and evening period of the day.

Geochemical assessment for groundwater quality was carried in 15 stations along Bay of Bengal of Vizianagaram district, Andhra Pradesh. Statistical and geochemical interpretations of major ions revealed geological and chemical factors with mechanisms controlling quality and quantity of groundwater.

The present work seeks to assess the spatial distribution and level of fluoride in the groundwater of different blocks of Bankura district, West Bengal. This is the first concerted attempt to highlight the vicious presence of fluoride in the sub-surface environment of Bankura and its gradual ingress in tube well water.

Photocatalysis is an advanced oxidation process aiming at the complete conversion of harmful and toxic dissolved contaminants in natural or drinking water into carbon dioxide, water and inorganics in presence of semiconducting materials such as TiO2 and ZnO, which act as catalysts.

Keeping in focus the rural area and its distribution system, a Regional Rural Water Supply Scheme (RRWSS) for 30 villages in Nashik District consisting of a distribution system from MBR (Master Balancing Reservoir) to GSR (Ground Service Reservoirs) of 30 villages is selected as a reference scheme for this study.

Egypt, with the highest population in the area, is already considered to be in the water scarcity limit. Thus, there is an increasing need for desalted water to cope with the population growth and development. It is essential to determine the capital, operating and unit cost for producing water by desalination.

Urban waste management are being increasingly transformed from a disposal-based linear system to a recovery-based closed-loop system that promotes the conservation of water and nutrient resources thereby contributing to sustainable development. The current manuscript compares the decentralized and centralized approaches to wastewater systems by citing several studies that have listed various well-defined criteria to choose decentralized systems over centralized systems.

Water industry due to its unique nature faces many problems. Civic bodies will have to manage the supply of water from the limited water resources in order to fulfill the ever increasing demand of water. It is a very challenging task. This paper presents the results of the study carried out to solve the problems faced by the water supply industry in urban areas with the help of GIS.

Ground water abstraction is increasing day by day due to its increasing demand for various uses. Hosur union of Krishnagiri District, completely depends on ground water for drinking purpose, since the surface water from Penniyar River is very limited. In the present study the assessment of ground water quantity of this region is taken up, to ascertain the safe yield.

This study evaluated the microbiological quality of treated and untreated water samples from urban and rural communities and examined the relationship between coliforms occurence & average water temperature and a comparison of the rainfall levels.
