Rock delays work on sewer
TECHNICAL difficulties mean works to replace corroding iron pipes in the Town Quay area of Fowey have been postponed.
The works are required to replace old iron sewer pipes that are effected by salt water corrosion, with more modern plastic pipes which predate the upgrading of the town’s pipe network on the river foreshore in 1995.
But South West Water have delayed the planned works due to problems created by the level of rocks below the foreshore where the planned works were due to take place.
To prevent future pollution incidents, South West Water (SWW) plans to replace the remaining iron pipes at Town Quay and Caffa Mill (Passage Slip) sewage pumping stations.
The pipes in and out of Town Quay are both significantly below water level which creates difficulties for engineers to access the pipes in the slipway and foreshore who need to create a dry area for works to take place known as a cofferdam.
Works were due to start last month and be completed by Friday, April 7, however they have now been postponed until the autumn.
A SWW spokesman explained: “Our marine contractors now need to review the method for constructing the cofferdam and further investigations are required to determine the rock level below the foreshore.
“This would mean delaying this section of work until May or June, which would cause considerable disruption during the peak holiday season.
“For this reason, we met members of the town council, the Harbour Master and Assistant Harbour Master last Thursday to discuss the situation and agreed that we would return to complete the rising main replacement work in late September / October.
“Work is still progressing on the gravity sewer within the slipway chamber, which will require the low tides of w/c March 13 and possibly w/c March 27.
“The rising main replacement at Caffa Mill pumping station is operational except for replacement pipe work within the pumping station, which will be complete by the end of April.
“When we have technical details and programme for the autumn we will have another meeting with representatives of the Town Council and the Harbour Master.”
