Newmachar Wastewater Treatment Works

What are we doing? 

A new Sewer Overflow has been installed, along with a larger storm tank, both of which will help to reduce discharges to the local watercourse during storms.

As the Wastewater Treatment Works is situated next to two burns, a new flood compensation area has been constructed to the south of the site. Work is ongoing to landscape the area to resemble a natural valley. 

The majority of the work has taken place within the existing footprint of the site, and operatives have worked with the community to minimise disruption during construction.

Preparation work involving the clearance of some trees took place before the bird nesting season ahead of the main construction work.

Why are we doing it? 

This investment project will increase capacity at the WWTW by 20%, enabling further residential growth in this area of Aberdeenshire while continuing to protect the local environment. 

Latest Update - April 2026

This project is nearing completion. Since work began on site in March 2024, several key milestones have been reached.

The new storm tank has been installed and the Sewer Overflow pipework is fully completed. 

The Returned Activated Sludge and Activated Sludge pipe work has been installed.

The base and kiosk for the Motor Control Centre (MCC) has been completed, with the MCC delivered to site.

A new sludge tank has also been erected and the flood alleviation area is now complete, with landscaping work ongoing.

Operatives are in the process of reinstating the main site compound and fencing and landscaping work are ongoing.

We would like to thank everyone affected for their patience and understanding.
