Water of Leith
- We are improving Edinburgh's waste water systems with a multi-million pound investment. The project will improve the environment around the Water of Leith. Our alliance partners amey Black and Veatch (aBV) will be carrying out the work.
- Once complete, this new infrastructure will help prevent items which are wrongly flushed down the toilet - from overflowing into the Water of Leith
- The project requires upgrade work to various Combined Sewer Overflows (CSOs) at 14 locations along or near the Water of Leith.
- We will be updating these project pages as the project progresses.
What we are doing
The work includes the installation of new pipework, chambers and screens to reduce the risk of sewage related debris entering the Water of Leith and removing the Unsatisfactory Intermittent Discharges (UIDs) thus improving the aesthetics and reducing the environmental impact of storm overflows on the Water of Leith. This will result in an improved watercourse for all its users.
Work started in July 2020 and overall the combined projects are expected to take around 2 years to complete.
