I don't understand how the authorities approach fixing the problem of what appears to me to be a manhole that is not level with the road surface . Or how it's decided whose responsibilty it is .Southwark ,if they maintain the road ? Thames Water if they maintain the cover ? Southwark@s on line reporting lists Broken covers as an item that can be reported ,suggesting that they take responsibilty for broken/damaged covers .Nothing about noisy ones . I had a frustrating telephone conversation yesterday which I imagine constituted an update . One of the covers I reported will be "thoroughly investigated " in the next 2 to 5 working days . I had to correct the quoted location and was unable to understand why the caller couldn't discuss the second cover that I had reported at the same time . I was told that the tarmac work to the cover opposite Mulberry Close had not been instigated by Thames Water . It all seems hopeless to me ,the cover near 161 Barry Rd has been noisy ( with brief respites ) for 12 months now .
