This paper reviews water institutional reforms in Sri Lanka by contrasting those observed during the 1980s with those proposed during the 1990s. While the earlier reforms focused on the irrigation sector that yielded quicker benefits and low political risks, recent reforms have covered macro institutions and the whole water sector where the benefits are gradual and less visible but with high political risks. As the earlier reforms were packaged as part of larger investment programs, they had in-built incentives and strong proponents. But recent reforms not only lacked such conditions but also faced an ideologically charged hostile environment. Despite the current failure of the reforms, their future prospect is not that bleak in view of the emerging consensus on most issues and the continuing government commitment to reform. The Sri Lankan case also provides evidence for the effects of transaction cost and political economy factors, the tactical benefits of reform packaging, sequencing and timing, and the role of stakeholders' perception, learning and information in articulating the demand for change.
Heap Leach Pad Monitoring - Case Study
2D Electrical Resistivity Imaging Objective Study was performed at a Heap Leach Copper Mining site in Chile to determine the impervious zones for the irrigation. The first base survey is performed to locate the impervious zones to be able to improve irrigations. The second monitoring survey is performed after 50 days of irrigation through drilled two boreholes to observe the improvement of irrigations. Layout The surveys were performed in 12th of May and 1st July 2015 in Chile with AGI SuperSting WiFi R8...
Times are changing: Wastewater as a resource
Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like population growth and climate change, more and more people around the planet are realizing that water can be treated and...
Delta Drainage and Irrigation System - Case Study
BackgroundDelta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean.Of the 13,500 hectares (ha) watershed, 6,300 ha is active agricultural land, 3,500 ha is the environmentally sensitive Burns Bog, and the rest is a mix of urban and industrial...
A combined reed bed/freezing bed technology for septage treatment and reuse in cold climate regions
A combined reed bed-freezing bed (RB-FB) technology was effective at treating septage under Canadian climatic conditions over a 5-year period with average loading rates of 82–104 kg TS/m2/y. Varying hydraulic and solid loading rates as well as the increasing sludge cake with time had little to no effect on treatment efficiency, with almost complete removal of organic matter, solids, heavy metals and nutrients. Filtrate concentrations varied significantly between the freeze-thaw and growing seasons for many...
