Engineer adjusting valve at Rowlyn weir and dam which form part of the water flow management Dolgarrog hydro scheme near Conwy,
The water from this weir passes along a leat that feeds Coedty reservoir above Dolgarrog. The water runs off river weirs along channels called leats or through pipes or conduits called penstocks through an intake grid chamber and onto a turbine generator. The turbine is controlled from a computerised panel and the amount of electricity generated is dependant on the amount and flow of water from the river or pipe. A tailrace returns the water after it has passed through the turbine to the main stream. The generation of this clean electricity will help prevent an annual release of many tonnes of the main greenhouse gas, carbon dioxide, which is a major contibutor to global warming and climate change.
