River Kelvin

A multi-million pound investment to improve the environment at the River Kelvin. Once complete this new infrastructure will help prevent items which are wrongly flushed down the toilet – wipes containing plastic, period produects etc – which due to extreme rainfall can overflow into the river.

The project requires upgrade work at 11 locations along or near the River Kelvin.

Nigg, Easter Ross

A waste water treatment process which maximises the production of biogas has helped a Scottish Water site in Aberdeen to transform its carbon footprint and start exporting energy to the national grid.

The CAMBI thermal hydrolysis plant was installed 20 years ago at Nigg Waste Water Treatment Works and since a programme of upgrade work was carried out over the past couple of years, it has now halved its CO2 emissions since 2019.

Winchburgh Waste Water Treatment Works

New multimillion pound treatment works in West Lothian.

Using award-winning Nereda technology treats waste water much faster than current treatments and takes away the need for pumps and mixers, meaning less energy and space is needed to treat a higher quantity of waste water. It also removes the need to use any chemicals during the treatment process which better protects the environment at local waterways.

Peebles/Bonny Craig

A Water Treatment Works (WTW) being built in the Scottish Borders. There were two key principles adopted for the design for the proposed WTW. The first was that it aim to have a net zero carbon footprint and the second was that landscape impact was minimised.

The building has been designed using an innovative modular technology where it will be constructed off site and delivered to Peebles in sections. There is a reduction in carbon emissions using this construction method as it has a considerably reduced construction programme, less site preparation and fewer vehicle movements for workforce, equipment and supplies. It is also proposed to install Photovoltaic (PV) solar panels on the roof of the building which we anticipate will provide an annual return of around 50MWh. The project is well under way.

Craigneuk, Airdire

An £11.5million investment to help reduce flood risk and reduce sewer flooding by increasing the capacity of the local combined sewer network. Installation of an underground storm tank and increase capacity of sewer pipes. Due to finish by spring/summer 22.

The works at Invercannie, Banchory
Invercannie Water Treatment Works, nr Banchory

An investment of £52 million, this two-year project will see the complete refurbishment of the existing plant, including a new water storage tank and a dissolved air filtration plant, with capacity to produce up to 63 million litres of drinking water a day for the area.  A new pumping station and associated pipework will also be installed.

Perth Waste Water Treatment Works solar + battery

Scottish Water has completed work on a milestone £2 million solar power scheme in Perth as part of its drive towards achieving net zero emissions by 2040. More than 2,500 solar panels are now installed on land adjoining Perth’s Waste Water Treatment Works at Sleepless Inch on the River Tay, with a combined generating capacity of just over 1 Megawatt (MW).
