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.

Protecting the environment

The project will help prevent rags, 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 off of Lochloy Road in Nairn.

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

The new storm overflow that we install will include a powered screen - an upgrade from the existing infrastructure - which will address aesthetic screening needs and help reduce the risk of sewer-related debris, such as wet wipes, entering the River Nairn.

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 for water quality or aesthetic – sewer related debris – reasons.

Under the banner ‘Draining the Rain, Enhancing the Environment’ the investment will help prevent sewer related debris such as wet wipes from entering the environment during periods of rainfall.

Latest Update - January 2026

After carrying out some final internal checks in response to some concerns raised from the community, we have now submitted our planning application regarding the location of our site compound.

Subject to the outcome of the planning process, and following feedback received about the best timing for the work, we are aiming to start construction in October 2026, with the majority of the work expected to be completed over the autumn and winter months.

Our team are also planning to hold a public drop-in event for the local community later in the year to provide more information and updates. We will share more details when available.
