• TO hear Thames Water suddenly found a 105-ton blockage is not very credible, (Concrete blockage in sewer, News online, April 19).
These sewers are inspected often and a build-up like this would take time. This was no “accident” and someone at Thames needs to explain why this was never discovered and controlled earlier.
