Project Overview

A £10m upgrade to the Waste Water Treatment Works (WWTW) serving customers in Ellon has been completed, boosting the site’s capacity by around one third. 

The project means that the WWTW is able to support the town’s growing community while continuing to protect the local environment.

Ellon WWTW

£10 million investment

The investment has delivered a comprehensive upgrade of the pre-existing WWTW

What We Did

The investment has delivered a comprehensive upgrade of the pre-existing WWTW, with the installation of new pumps, new screens, a new aeration system and new holding tanks. 
All the work took place within the boundary of the existing treatment works site, which is located between the River Ythan and Castle Road. It was delivered by Scottish Water’s alliance partner ESD, a joint venture involving MWH Treatment, Galliford Try and Binnies. 

The central challenge of the project was to ensure the treatment works could continue to operate to a high standard, even while extensive upgrade work took place to renew or replace much of the equipment involved. 


Why We Did This

Each stage of the existing treatment process has now been refurbished or upgraded to increase the site’s capacity and ensure that it can continue to meet the community’s needs for many years to come. We are very grateful for the patience and support of the local community while our team has been working on site – and hope we have succeeded in keeping any short term disruption to a minimum.
