Recent archaeological excavations in the nave of the church have confirmed the presence of medieval foundations, including a ceramic water supply pipe.
Pumped hydro and mini-hydro systems in water supply pipes between large dams and local storages can generate electricity at times of high demand, rather than relying on gas-fired power stations.
The first is that they can colonize and clog water supply pipes, thereby restricting water flow for systems used for cooling, fire-fighting, hydroelectricity, etc.
