UK: The City Council of Gloucestershire is planning to create a digital drainage map of the city. It is hoped that the system will allow potential drainage issues to be identified early and fixed before they become more serious.
So far the data has been collected from parts of Gloucester and Cheltenham and maps for these areas are expected to be finished by May 2011. A council spokesman said it meant the consequences of flooding in the summer of 2007 could be tackled more quickly.
Contractors use portable equipment – which receive GPS location data – to allow the location of drains, catch pits, chambers and manholes to be recorded. The digital drainage mapping project has already received interest from other councils and the National Assembly of Wales.
