Making an existing green scheme even greener
South West Water is working with the Environment Agency on a scheme to significantly improve salmon stocks on the river Tavy, while ensuring the future of the green renewable energy produced by Mary Tavy and Morwellham hydro power stations.
The scheme is part of a broader Environment Agency initiative to improve the ecology of the River Tavy and protect salmon stocks, which are widely regarded as a key indicator of the health of a river.
South West Water will contribute to the success of the scheme by adapting the hydro intakes at Abbey Weir in Tavistock and the nearby Hillbridge. Both intakes are being carefully re-designed with new automatic screening devices to prevent young salmon escaping into the water channels that feed Mary Tavy and Morwellham hydro power stations.
South West Water's Water Treatment Manager Mark Beighton said: "South West Water is committed to ensuring that our renewable energy projects remain positive to wildlife and river ecology and we are happy to work with the EA to ensure the hydro water intakes are as environmentally friendly as possible."
Bruce Newport for the Environment Agency said "These voluntary changes are of fundamental importance to the recovery of salmon stocks in the Tavy and we are very pleased that South West Water is working with us on this initiative."
South West Water's hydro power schemes currently prevent 7,000 tonnes of CO2 from entering the atmosphere every year. The improvements to the hydro intakes at Abbey Weir and Hillbridge will not only improve the health of the River Tavy but also help the company reduce its carbon footprint in the region.
As part of its massive contribution to the preservation and protection of the environment, South West Water now generates 5.73 MW of energy through hydro electric power and 1.46 MW through Combined Heat and Power (CHP -biogas). This combined energy production is enough to power a town with a population of over 12,000 people. Mary Tavy hydro power station alone generating one third of the company's green energy.
South West Water is a company committed to green generation, green energy purchases and increased energy efficiency to reduce its CO2 emissions. By working with the EA on the River Tavy initiative, the company is proactively improving the health of the river and achieving the perfect balance between renewable energy and the ecological improvement.
