Maining out at Manse Street

CWA’s Strategic Board visit Galashiels Manse Street project to see one of the biggest directional drilling rig in the UK tunnelling under the River Tweed.The project is part of three schemes which will deliver up-grade works to Howden Water Treatment Works, provide a new 12ML clear water tank and then main out the existing Manse Street works with a 12km pipe-line.

The 300 tonne drilling rig has successfully completed the first of two 500m drives under the River Tweed, the A70 and a high pressure gas main.

Using the drill has lessened disruption to customers on roads and reduced the risk of open cutting around a gas main. CWA’s Project Manage Barclay Smart said, “The drill passes be-neath the river on a curved path

so we started to drill 100m back from the bank to ensure the right trajectory. It was crucial for us to drill deep into solid rock 10m beneath the bed to lessen the chance of drilling fluids escaping and contaminating the river.

“The River Tweed is an SSSI (Site of Special Scientific Interest) with a number of ecological con-straints associated with the cross-ing relating to salmon, otters and crayfish. The team liaised with many stakeholders including

SEPA, The River Tweed Commis-sion and The Tweed Foundation. “We had a robust emergency response plan in case any fluid escaped into the river. Silt booms can be deployed with a curtain that drops down to contain leaks

and a vacuum machine which could remove the contamina-tion.”

CWA have been supported by AG Wilson who are delivering the construction element of the project, and GMAC Utilities who have managed the drilling.

Paul Sexton who visited the site with CWA’s board said, “These guys really enjoy what they are doing taking great pride in their work, it really shows on this site.

“Work on the project is going well and is a credit to the teams from Scottish Water’s CSD, CWA, AG Wilson and GMAC working together to improve resilience in theareaforourcustomers.”

These guys enjoy what they are doing, they take great pride in their work, it really shows on this site.
