Briefing – Planned work along the Water of Leith Walkway by Scottish Water between Baberton Loan and Colinton Dell

CSO Plan

This post provides information relating on the works Scottish Water (via their contractor Amey) will be carrying out which affect the Water of Leith Walkway between Baberton Loan and Colinton Dell from January 27th.

As many people may know, a trunk sewer runs along the Water of Leith. When it is full it overflows (normally raw sewage diluted with rainwater) into the Water of Leith via devices known as “Combined Sewer Overflows“. This work is focussed on the Combined Sewer Overflows. The table at the foot of this page outlines the planned work. 

Plan
Baberton Loan access arrangements. 

Whilst undertaking works at Baberton Loan Scottish Water will look to keep the pedestrian access open as much as possible, so the gates will normally be closed for the construction traffic, when traffic movements are required a Banksman will open the gate (which will temporarily close the path for Pedestrians), to allow the vehicles to pass, and then close the gate once through. Essentially when there are no traffic movements the pathway will be clear for Pedestrians to cross. Scottish Water are advising the residents of Woodhall Mains of these access arrangements.

Once Scottish Water have completed this work, the Council will then take forward work already planned to improve sections of the path. From them:

The following is the latest position I have received from Sustrans on this project. As envisaged, funding has been restricted to design work with construction delayed until the completion of the Scottish Water sewer outflow construction works within Colinton Dells.

“Sustrans have supported the design work on this route upgrade project to be shovel ready this year. It is our intention to fund the delivery of capital works following the Scottish Water works planned on the site for the first 6 months of 2020. We therefore intend to identify capital funds to deliver the route upgrade from our Network Development grant programme for 2020/2021.”

Once we have a clearer timescale for the completion of the SW works and Sustrans have confirmation of their 2020/2021 budgets we will be in a position to finalise the timescale for delivery of this project.
