Scottish Water has completed a major upgrade to the sewer network in Edinburgh.

The £2 million project involved the installation of a new screened storm overflow near Lord Ancrum Woods. The work, which began in March 2024, aimed to improve water quality and enhance the resilience of the sewer network.

The new overflow features a powered screen, control kiosk, and outfall pipe. The project was designed to minimise disruption to the local environment, particularly Lord Ancrum Woods.

Scottish Water's Karen Dee, Waste Water Services Strategy General Manager said: "We are delighted to have completed this vital project at Lord Ancrum Woods.

"The new screened overflow will play a crucial role in protecting the local watercourses and ensuring a cleaner, healthier environment for the community.

"We are extremely grateful to everyone for their patience and support during the planning and construction phases in what has proved to be a great example of collaborative work.

"With the community's help and co-operation, we have been able to deliver the project with minimal disruption, maintaining pedestrian access and access to local football fields throughout.

"The new overflow will significantly reduce the amount of sewage related debris entering the Mary Burn and into the River Esk, improving the overall water environment."

Overflows are an essential part of Scotland's waste water infrastructure, acting as relief points to ensure storm and excess rain water does not overwhelm the system during weather events to protect our customers' homes and businesses from flooding.

Over the past decade Scottish Water has invested £2.7 billion in improving and maintaining the country's public drainage system and infrastructure.

Karen Dee added "We are already investing record amounts to address the challenges of ageing infrastructure and climate change.

"This additional investment of £500million will enhance the monitoring of sewer systems, reduce sewage-related debris, and minimise overflows from the sewer network.

"People have a part to play as well by only flushing the three p's – pee, poo and toilet paper – to keep our sewers clear of blockages and our rivers and beaches clean.

"By working together, we can protect properties, communities and the environment against the impact of increasing demand and climate change."
