Understanding drivers and barriers: the key to water use behaviour change
In southwest Victoria, like many other regions in Australia, drought, climate change and population growth have exposed gaps in water supply. To develop effective demand management strategies for rural and regional areas, this paper investigates the drivers and barriers to water saving in southwest Victoria. Although the majority of people felt water saving was important, the drivers for water ...

Application of solar disinfection for treatment of contaminated public water supply in a developing country: field observations
A sustainable and low-cost point-of-use household drinking water solar disinfection (SODIS) technology was successfully applied to treat microbiologically contaminated water. Field experiments were conducted to determine the efficiency of SODIS and evaluate the potential benefits and limitations of SODIS under local climatic conditions in Karachi, Pakistan. In order to enhance the efficiency of ...

Chinese Strategic Environmental Assessment system and its application in water resources development plan of the Yellow River
The changing pattern and intricate correlation between water supply and demand, social development, and ecological conditions over the past decade were presented. To gauge environmental impacts from implementation of new water resources development plan, a Strategic Environmental Assessment (SEA) was carried out. The residential, agricultural, and industrial water demand in 2010 at different ...

Radon distribution in groundwater of Taiwan
Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...

Role of small-scale independent providers in water and sanitation
Small-scale independent providers (SSIPs) and households are good for 10?69% of the household water supply and sometimes up to 95% of the sanitation solutions in cities in developing countries. Different types of SSIP can be distinguished. They could be allowed to make a more important contribution to drinking water and sanitation in a situation where many governments cannot be the only one to ...

Inequalities in microbial contamination of drinking water supplies in urban areas: the case of Lilongwe, Malawi
Over past decades strategies for improving access to drinking water in cities of the Global South have mainly focused on increasing coverage, while water quality has often been overlooked. This paper focuses on drinking water quality in the centralized water supply network of Lilongwe, the capital of Malawi. It shows how microbial contamination of drinking water is unequally distributed to ...

Estimating regional water demand in Seoul, South Korea, using principal component and cluster analysis
ABSTRACTIn Seoul, the multiple regression models were used to estimate future water demand and to verify the ability of the water supply to cope with regional development. A regional development project extending over two districts was planned to stimulate the regional economy of Seoul in October 2003, and multiple regression models for each district were developed to verify the capacity of water ...

Design Considerations for Multilevel Monitoring Wells
Untitled Document ABSTRACT Much has been written about the advantages of multilevel (multiport) monitoring wells over clustered or nested monitoring wells, however, there is little published information that provides helpful hints and 'dos and don'ts' for planning successful multilevel well projects. This paper discusses the differences in both design and construction ...
