“…Choice modelling has gained recognition in the field of environmental valuation (Giergiczny and Kronenberg, 2014) and is increasingly applied to value water resources such as wetlands (e.g., Carlsson et al, 2003;Birol et al, 2006a;Milon and Scrogin, 2006) or water services (e.g., Snowball et al, 2008;Kanyoka et al, 2008). In relation to wastewater, in a study by Birol and Das (2010), choice modelling was used to estimate the local public's WTP for improvements in the capacity and technology of a sewage treatment plant in Chandernagore municipality in India. Another study by Genius et al (2012) applied choice modelling to elicit the value of the attributes of a wastewater treatment plant in a rural area in Greece; the attributes included -among others -water quality and irrigation with recycled water.…”

Wastewater has emerged as an alternative source of water. Since the agricultural sector remains the largest water user world-wide, it is the main potential user of treated wastewater. However, while there are trade-offs in using wastewater, it may be the only option in water-scarce regions. South Africa has included water reuse as a policy option; hence the aim of this study is to understand farmers' preferences regarding water reuse frameworks for irrigation. A choice modelling approach was applied to identify the elements defining these frameworks and to quantify their relative importance amongst farmers in the agricultural hinterland of Cape Town. The findings suggest that water reuse is acceptable to farmers in the area. Furthermore, they prefer options that guarantee good quality water and low levels of restrictions on use practices. Due to low trust in water service providers, farmers are willing to pay for a privately-managed scheme for water reuse, which suggests that the management model for implementing such schemes is important.

“…The upstream is divided into three tributaries: the north branch is the main tributary named as Arun, the west branch as Sun Kosi and the east branch as Tamor. The three come together to form the Kosi River, near Dan Kute, which finally flows into the Ganges River in India (Birol and Das, 2010) (Fig. 2).…”

The Kosi River is an important tributary of the Ganges River, which passes through China, Nepal and India. With a basin area of 71 500 km², the Kosi River has the largest elevation drop in the world (from 8848 m of Mt Everest to 60 m of the Ganges Plain) and covers a broad spectrum of climate, soil, vegetation and socioeconomic zones. The basin suffers from multiple water related hazards including glacial lake outburst, debris flow, landslides, flooding, drought, soil erosion and sedimentation. This paper describes the characteristics of water hazards in the basin, based on the literature review and site investigation covering hydrology, meteorology, geology, geomorphology and socio-economics. Glacial lake outbursts are a huge threat to the local population in the region and they usually further trigger landslides and debris flows. Floods are usually a result of interaction between man-made hydraulic structures and the natural environment. Debris flows are widespread and occur in clusters. Droughts tend to last over long periods and affect vast areas. Rapid population increase, the decline of ecosystems and climate change could further exacerbate various hazards in the region. The paper has proposed a set of mitigating strategies and measures. It is an arduous challenge to implement them in practice. More investigations are needed to fill in the knowledge gaps

Abstrac-Waste water treatment is the process of removing existing contaminants to make water becomes fit for disposal or reuse. The waste water generally contains 99.9% water and 0.1% of solid impurities; thus, it has a large potential as a source of water for different purposes such as fish ponds, comfort rooms, cleaning source, among others. Treated water can be used back into the natural environment without adverse ecological impact. In the Philippines, the most commonly used treatment methods for beverage companies are pond/lagoon system and activated sludge system. This study aimed to characterize and differentiate the wastewater treatment methods used by Coca-Cola Bottlers Company (CCBC) and the Tanduay Distillery, Inc. (TDI),a multi-national and local company, respectively. This study also aimed to identify the most effective and commercially viable treatment system as well as determine effective waste management system. Study on waste water treatment systems in selected multi-national and local beverage companies in the Philippines are recommended with the end view of obtaining the effects of treated water in nearby communities where these companies are located. Industrial wastewater treatment is important to generate alternative source of water as well as to protect and maintain the balanced ecosystem in the community.
