Project Overview

We are installing a new and improved storm overflow chamber off of Lochloy Road in Nairn.

The new chamber will include a powered screen, which will help prevent sewer related debris from entering the River Nairn.

This project is part of our £500m Improving Urban Waters programme.

Work is currently planned to begin in Autumn 2026.

Protecting the environment

The project will help prevent things like wet wipes and other sewer related debris from entering the River Nairn

What We Are Doing

We are installing a new screened storm overflow chamber within the Scotmid car park by Lochloy Road in Nairn.

The existing overflow chamber is currently located in the centre of the A96 at its junction with Lochloy Road.

The new storm overflow that we install will include a powered screen - an upgrade from the existing infrastructure - which is designed to retain sewer-related debris, such as wet wipes, within the sewer when the overflow need to operate.

Our team will also be carrying out some local sewer realignment works to connect the new overflow chamber to the existing sewer network.

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 - to address impacts on water quality and/or the risk of sewer related debris being released into the environment during periods of heavy rainfall.

Under the banner ‘Draining the Rain, Enhancing the Environment’ the investment will help protect the River Nairn and the wider environment from pollution with things like wet wipes, sanitory products and other items which shouldn't be flushed down toilets.
