Corstorphine Road
Project Overview
We are installing new screens and spill chambers to a storm overflow under Corstorphine Road to help prevent sewer related debris from entering the Water of Leith.
Work is due to get underway at the beginning of June 2025 for approximately six months.
During delivery, Corstorphine Road will be reduced to one lane under temporary traffic lights between Ormidale Terrace and Murrayfield Gardens.

The project will help prevent rags, wet wipes and other sewer related debris from entering the watercourse.

What We Are Doing
New screens and spill chambers are being installed to our storm overflow underneath Corstorphine Road at Ormidale Terrace.
The existing spill pipe and outfall will be retained.
When excess rainwater is discharged, the new screens will ensure any sewer related debris does not end up in the Water of Leith.

Why We Are Doing It
Working closely with the Scottish Environment Protection Agency (SEPA) Scottish Water has identified priority storm overflows for improvement or replacement for water quality or aesthetic – sewer related debris – reasons.
Under the banner ‘Draining the Rain, Enhancing the Environment’ the investment will help prevent sewage related debris such as wet wipes from entering the environment during periods of rainfall.
