This study evaluated user preferences among three alternative in-home water treatment technologies suitable for households relying on trucked water in El Paso County, Texas, which is on the border with Mexico. The three technologies were: chlorination of household storage tanks, small-scale batch chlorination, and point-of-use ultraviolet disinfection. Fifteen households used each of the three ...

Storage tanks are commonly used for domestic hot water (DHW) preparation in large buildings supplied by district heating (DH), especially to cope with peak demand. The charging control of DHW tank systems is often suboptimal, increasing return temperatures and harming the overall DH operation efficiency. This paper presents two novel concepts optimize charging, satisfying comfort hygienic requi...

irrigation. The idea was to build 100 m of catchment area, and two concrete water storage tanks and irrigate one mu (1/15 hectare) of courtyard land devoted to cash crop production. In practice, the 1-2-1 program focused on building water tanks for household use, with roofs and courtyards serving as the principal catchment surfaces that channel water into the tank. County and township governmen...

This system aims to design and develop a prototype of an automatic for cleaning domestic cylindrical water tanks. The proposed includes simple mechanism with centrifugal force. Household tanks are supposed provide safe cleaning, gardening, cooking, drinking. majority the time coming into tank comes dust dirt particles. Over time, sludge or sediment may build up, contaminate cause illnesses in h...

Safe, accessible, and good water quality are essential characteristics for reducing various waterborne diseases. Since domestic is the most consumed by Lebanese people, cleaning household tanks important to prevent their exposure pathogenic microorganisms. Generally, all stages of value chain sector still imperfect. Thus, should be regularly tested, especially in impoverished landmarks where wo...

Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and dynamic...
