Thousands of water supplies safeguardedSouth West Water is investing over half a million pounds to safeguard the water supplies of 30 thousand homes located between Tavistock and Plymouth by the end of March.
Nearly 2.5 miles (4006 metres) of water mains from Dousland water treatment works will be upgraded using various techniques to ensure the pipelines remain effective for at least the next 100 years. Some of these mains have been in place since 1940.  Thousands of water supplies safeguarded This year alone South West Water will spend over £30 million to improve nearly 250 miles of the region's water mains, putting the sparkle back into more South West water supplies. A 21inch iron main has been renovated using a large diameter lining rig the size of an articulated lorry to scrape out corroded iron pipes and reline with a polymeric coating to safeguard future water quality. This main which supplies Tavistock, Milton Coombe, and parts of the South Hams has produced a record 9 tons of corroded iron along every 100 to 150 metre stretch during the relining process. This is due to a low flow rate along the main allowing a higher than normal build up. Before the project was started a full investigation was carried out to ascertain the condition of the water mains and find the most effective renovation method. Some pipelines from Roborough reservoir will be replaced if necessary using the latest specialist materials. - ENDS - For further information please contact Dina Chandler, Communications Officer on 01392 443021.
