Edge Lane Liverpool to remain closed for repairs on blocked sewer
United Utilities has been working with the council to investigate the hole which has opened up on Edge Lane.
Engineers have now identified that a brick sewer is blocked beneath the road.
The sewer is around 7 metres deep and the engineering teams are now liaising with other utilities and the emergency services to work out the best way to tackle repairs.
A high pressure gas main runs along the opposite side of the carriageway and repairs will have to be managed carefully to avoid any further disruption.
United Utilities wastewater strategy manager Tony Griffiths said: “At this stage we don’t know what has caused the sewer to block up, it could be ground movement or subsidence.
“Our first priority is to make the area safe and set up a bypass pumping system so that wastewater flows can get past the blocked section. It may then be possible to open the opposite carriageway and set up a contraflow system for traffic while repairs take place.
“It’s hard to say how long repairs will take until we can actually dig down and fully assess the situation, but it’s likely to be weeks rather than days.”
Liverpool Council has set up a temporary diversion route and motorists are asked to follow the signs.
