    Context

    Pumping of water for domestic and productive uses has been difficult to maintain in Tanzania. This challenge is highly attributed by the higher costs of pumping water using conventional means such as diesel generators and electricity.

    Solar Photovoltaic (PV) technologies have enabled rural communities of Tanzania to apply this technology for lighting, water pumping, charging of cell phones, etc. Community water projects using solar pumps have benefitted from reduced running costs as compared to diesel or electric water pumps.

    Solomon Islands comprise hundreds of islands.  Solomon Islands Water Authority (SW), a state-owned enterprise, is mandated to operate as the provider of municipal water and wastewater services. About 95% of total installed capacity of electricity generation in Solomon Islands is based on fossil fuels, and the balance 5% is through renewable energy sources. The electricity tariff of Solomon Islands is one of the highest in the Pacific since a major share of electricity in the Islands is met through fossil fuels. 

  • Tamar Technological Development r seals eliminate leakages in the main factories in Israel and were successfully installed in .USA Italy Brazil and Netherlands. The new MTZ shaft sealing technology has been introduced by Tamar Technologies This product is especially effective in sealing pumpage with particulates as well as for clear liquids It has application for pumps mixers agitators ribbon blenders and fans in addition to sealing shafts for dry powder handling. The Tamar Seal is analogous to a double mechanical seal that uses a flexible sealant as a barrier fluid.

  • Technology

    Mekorot implements state-of the-art technological solutions and cutting-edge processes that succeeded in maximizing the utilization of Israel’s water resources. The systems include a national network of fully-automated control centres. These centres ensure the continuous functioning of Mekorot’s 3000 water installations including wells pumping stations treatment facilities reservoirs and pipelines. Advanced communications devices provide online real-time information about water quality and water supply while allowing remote control of vital systems.

  • Objective

    A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. Solar water pumps is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.

    Small-scale private irrigation schemes have been the driving force behind the expansion of irrigated areas in Nigeria, despite government efforts to promote large-scale public irrigation schemes. This article empirically assesses the effect of unobserved transaction costs for Nigerian farmers" when investing in irrigation pumps, using the baseline survey data for the Second Fadama Development Program (Fadama II).

    According to this study, the Malawi Government has intensified the use of treadle pumps. The treadle pump as a result is gaining popularity among small-holder farmers throughout the country. This study was conducted in two purposely selected districts of Blantyre in the Southern Region and Mchinji in the Central Region of Malawi. The findings of the study demonstrate that the treadle pump is important for the generation of income, reduction of poverty and maintenance of food security among smallholder farmers in Malawi.

  • Objective

    This article demonstrates the Comprehensive Approach, by means of an example of an inter-basin transfer scheme with significant pumping costs associated with water transfers. Uncertainties about future water transfers and associated variable costs are provided by stochastic simulation modelling. The incremental approach is shown to be severely biased with respect to variable costs and it is shown that this bias leads to significantly different estimations of likely life-cycle project costs. Such differences conceivably lead to suboptimal decision-making.

    Enhancing water productivity is often recommended as a "soft option" in addressing the problem of increasing water scarcity. In this study, authors analysed the water productivity and GHG implications of water reuse through pumping groundwater and creek water, and compare this with gravity-fed canal irrigation in the Upper Pampanga River Integrated Irrigation System (UPRIIS) in the Philippines. Water productivity indicators show that water reuse contributes significantly to water productivity.
