Overflowing blocked gully

This is a reoccurring problem that happens often. The gully half way down Gorchester Gardens is blocked as the main hole cover is broken causing raw sewage to flow down the pavement. This is a health hazard. I must have reported this problem to the council more than 10 times over the last few years and it keeps reoccurring. Every time a lorry or bin van goes onto the pavement(which happens often) the drain cover is broken and the problem occurs. The sewage is currently flowing onto the pavement. This has been going to for the last few days.
