Shutdown strategy saves time and money

摘要

Away to shutdown an entire sewage treatment works without using storm facilities has been devised by a Costain team working at Severn Trent Water's Stratford Milcote facility. The strategy was developed and trialled while the team installed a new inlet works with associated screens and handling at the sewage treatment works. Tom Grainger-White, Costain senior site agent, said the strategy reduces risk and saves money. He said: "Traditionally when a treatment works is shutdown, foul water is transferred to tankers and then transported to other sites. By compiling information such as how wastewater flowed between the 15 pump stations that fed the site, and carrying out tests to check those interactions, we were able to turn off individual stations.
