The La Romaine hydropower complex is the largest infrastructure project underway in Canada. Located about 55 km from Havre-Saint-Pierre, over 2 000 workers are living on the premises. The accommodations comprise dormitories, offices, cafeterias, a leisure center, a bar and a convenience store. . As such, and in sync with its sustainable development vision, Hydro-Québec had to comply with stringent discharge standards for the treatment of the wastewater produced by this camp. And wastewater treatment in remote and isolated locations is a significant challenge. Moreover, the wastewater treatment equipment had to be demobilized after use.
Understanding water-society nexus: insights from Turkey's small-scale hydropower policy
Turkey's recent venture involving the construction of hundreds of small-scale hydropower projects is a significant trend, both in regard to its contribution to Turkey's hydroelectricity production and the social and environmental impact of these projects at the local level. Turkey's hydropower policy was premised on a conventional understanding of water driven by science, technology, and the market. This approach, however, does not seem to have paid sufficient attention to the socio-ecological characteristics of...
Understanding India-Pakistan water politics since the signing of the Indus Water Treaty
On 19 September 1960, the Indus Water Treaty (IWT) was signed between India and Pakistan, presumably resolving the conflict of Indus water sharing. Nevertheless, over the years the conflict has re-appeared, dragging both the riparian states into confrontation. This paper explores the reasons that lead to conflict despite the Indus water sharing having already been resolved by the IWT. Analysis of the documentation shows that increasing construction of hydropower projects by India instigates conflict between the...
Modeling future changes in the North-Estonian hydropower production by using SWAT
Climate change is altering temperature, precipitation, and other climatic parameters, affecting sectors dependent on water resources, e.g. energy production. The purpose of this study is to analyze the possible influences of climate change on hydropower potential in North Estonia. In Estonian run-of-river hydropower plants, energy comes mainly from water volume. Thus, changes in hydropower production are related to changes in river runoff. The Soil and Water Assessment Tool (SWAT) model is used to study runoff...
A real-time operation of the Three Gorges Reservoir with flood risk analysis
Risk analysis is essential to reservoir operation. In this study, a new analysis for reservoir operation is proposed to enhance the utilization rate of the flood water from the Three Gorges Reservoir (TGR) during the flood season. Based on five scenarios of hydrology forecasting with the adaptive neuro-fuzzy inference system (ANFIS), a multi-objective optimum operation was implemented employing the risk control constraints of the genetic algorithm (GA) for the TGR. The results of this analysis indicated that the...
DSEP100 Mains Decoupling Relays for hydropower projects in remote locations in the Cumbrian Lake District, UK. Old decommissioned water wheels in Ambleside, Blencathra and Langdale have been recently refurbished and brought back into use as sophisticated hydropower turbines which are now working in parallel with the grid, supplementing the local electricity supply. The DSEP100 protection relay was chosen for this application because of it’s extensive protection capabilities, reliability and safety...
