Scottish Water’s £2.5million project to alleviate flooding on the A8 East Hamilton Street in Greenock is to facilitate delivery of a second project to benefit Inverclyde.

A separate scheme to reline a section of the local sewer is to be carried out using the same road traffic management arrangements that have been in place for the past five months.

Georgina Reid, Scottish Water’s corporate affairs regional affairs manager in the west said: “Our alliance partner Caledonia Water Alliance is involved in a Scotland-wide programme to survey and where required upgrade sections of our 33,000-mile-long network of sewers.

“Specialist contractors carrying out this work took the opportunity to examine a section of pipework in the immediate vicinity of Pottery Street under the current traffic management.

“The survey found remedial work is required so we have decided to carry it out using the road permissions already granted for the flood alleviation project.”

The flood alleviation project which is close to completion has seen a new screened Combined Sewer Overflow (CSO) constructed in the grounds of Inverclyde Council’s Pottery Street depot.

Works to upgrade and connect the CSO to the local sewer network has involved approximately five months of traffic management on the A8 itself with the road reduced to one lane in each direction.

As a contingency should these be delayed by bad weather or unforeseen circumstances an extension to the Temporary Traffic Restriction Order (TTRO) was successfully secured until the end of February 2024.

The new sewer relining project will now be delivered using this TTRO extension.

Georgina Reid added: “In practical terms we will be working on the road for approximately three to four weeks longer than originally scheduled while we deliver this extra project under similar traffic management arrangements.

“The benefit of doing this means we will not have to return to the site later in the year and excavate the newly reinstated road and central reservation. It also means the sewer relining can be completed in approximately half the time it would otherwise require.

“I can appreciate there will be a sense of disappointment at what is perceived as a delay.

“This is actually an additional project being delivered in less time and with less disruption than would otherwise be the case.”
