Fully rehabilitation: integrating a small hydro cascade into a water supply system
Abstract
A rehabilitation scheme at the more than 100 year-old Fully hydro scheme, where the penstock had shown signs of ageing, has involved converting the original single power station into a cascade of three plants, which have been integrated in a municipal water supply system. This paper presents the main stages of the rehabilitation studies, the reasons for the solution adopted, as well as an overview of the construction challenges. The scheme is now nearing completion, with the last small plant scheduled to be commissioned in December.

Water supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions (urban versus rural).
Water supply network
A water supply network or water supply system is a system of engineered hydrologic and hydraulic components that provide water supply. A water supply system typically includes the following: A drainage basin (see water purification – sources of drinking water) A raw water collection point (above or below ground) where the water accumulates, such as a lake, a river, or groundwater from an underground aquifer. Raw water may be transferred using uncovered ground-level aqueducts, covered tunnels, or underground water pipes to water purification facilities.
History of water supply and sanitation
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely. Major human settlements could initially develop only where fresh surface water was plentiful, such as near rivers or natural springs.

Laurent Villard, Stephan Brunner, Alberto Bottino, Ben McMillan, Moahan Murugappan
Long global gyrokinetic turbulence simulations are particularly challenging in situations where the system deviates strongly from its initial state and when fluctuation levels are high, for example, in strong gradient regions. For particle-in-cell simulati ...

Fabio Nobile, Yoshihito Kazashi, Eva Vidlicková
We consider the Dynamical Low Rank (DLR) approximation of random parabolic equations and propose a class of fully discrete numerical schemes. Similarly to the continuous DLR approximation, our schemes are shown to satisfy a discrete variational formulation ...
