Persistent Blocked Drain, Lorne Hotel, Glasgow
C Hanlon Drainage was called by Logical Land Developments Ltd to the Lorne Hotel in Kelvinside, Glasgow to investigate a drainage problem the hotel had been experiencing. The hotel has been going through a £7 million upgrade.
Various drainage companies had been to site but were unable to detect why the drainage system kept blocking. C Hanlon drainage engineers used high pressure water jetting on the internal drainage system and drain tracing techniques to locate the flow of the drain. The drainage run was located to an external manhole chamber on the pavement. The manhole chamber was over 5m deep. Due to the depth of the manhole chamber, confined space manhole entry equipment was required to enter the chamber. Engineers entered the manhole chamber and removed an internal access cover which had fallen into the drainage channel and was causing the blockages. Once the access cover was removed, the drain was high pressure water jetted and the drain was restored to full flowing capacity.
Works were completed on time and Site Manager was pleased with the result.
