Howden WTW and Greenock SCADA hits major milestone!
18th December 2024
The Howden WTW project achieved acceptance on 18th December. This upgrade to the works is a key part in Scottish Water’s 25 year strategy for the Borders network and is a major milestone for ESD. The whole team have shown a huge amount of dedication, commitment and tenacity to get us to this point and should feel very proud of what they have delivered for our client.
We are delighted to announce the successful acceptance of the Greenock SCADA Replacement Project. This extremely complex project, which has been over 7 years in the design and prepare stage, will replace the existing redundant distributed control system with a new specification compliant Siemens PLC and SCADA system. This new state-of-the-art system will allow the works to be maintained for years to come. This milestone has only been achieved by close collaboration between ESD, Scottish Water and the systems integrator BGEN.
Glenfarg WTW Visitors!
November 2024
A few weeks ago, a family of beavers was discovered near Glenfarg WTW, which is due to undergo a major £114m upgrade. They have now been successfully relocated to the Cairngorms National Park.
The construction works would have seriously disturbed the beavers’ habitat and, as they are stubborn creatures, they probably would not have moved on of their own accord.
With expert advice and support from The Beaver Trust, the animals have been relocated to their new home as shown in the video below, posted by Scottish Water on YouTube.

Remember; Nothing we do is so important that we cannot take the time to do it safely.
Official Opening Ceremony for Invercannie WTW
September 2024
Friday 20th September saw the official opening ceremony of the revamped £60m Invercannie WTW near Banchory. The event was attended by Cllr Judy Whyte, Provost of Aberdeenshire, and Scottish Water’s Board Chair, Deirdre Michie, and Chief Executive, Alex Plant (See photos) – as well as representatives of ESD.

Invercannie WTW WiS
July 2024
On the 18th July, the ESD Team at Invercannie WTW hit a major milestone for the project and the greater Aberdeen area with Water in Supply for the new Chlorine Contact Tanks, 19ML Clear Water Tanks, Lime Make-Up and Dosing System, Sodium Hypochlorite Dosing System, and Integration of the existing Ammonia Dosing System. This £56million pound investment project is the largest infrastructure work at Invercannie WTW since the building of the 1924 Aqueduct. With the new DAF treatment on the raw water and now the new CCT, CWTs and Chemical dosing packages, Invercannie WTW is more resilient to change in Raw Water quality and now has storage capacity of 19ML further protecting the valuable water supply to Aberdeen and the surrounding towns and villages.
A fantastic effort from the site team and supply chain to finally hit this major milestone! Well Done all!!
Milestone at Carron Valley
July 2024
The site team at Carron Valley WTW reached a project milestone by successfully getting the new powdered activated carbon (PAC) system up and running, achieving water into supply (WIS).
Having the new PAC plant operating was critical to meeting a DWQR requirement, and the team worked tirelessly alongside Ross-shire Engineering to ensure the deadline was met. PAC is used to neutralise an earthy taste in drinking water caused by an algae, Geosmin, found in Carron Valley Reservoir in the summer months.
The team’s hard work since March last year means that the temporary PAC system that has been in use can be removed from service, and the new system can be handed over to Scottish Water following a reliability period and operator training. ESD remain on site at Carron Valley to manage a complete filter refurbishment, construction of a new service water pipeline and pump kiosk, and upgrades of all remaining chemical dosing systems.

South Commons hits important Milestone
May 2024
A major milestone in the Scottish Borders on 1st May 2024. Water into Supply (WIS) was achieved for the first cell of a new South Common 12 million litre Clear Water Tank (CWT), This is part of the £30m+ scheme ESD is delivering to improve WQ and resilience of supplies throughout the Central Borders.
New Milestone at Dhu Loch WTW
March 2024
The new MIEX (Magnetic Ion Exchange) plant at Dhu Loch WTW (Water Treatment Works) on the Isle of Bute reached a key project milestone this week with Scottish Water approval being granted to go ahead to Water into Supply (WiS).
The MIEX process has been proven to reduce the natural organic matter content in the raw water that combine with disinfectant by-products resulting in higher levels of THM’s. Lessons Learned from the MIEX plants previously delivered by ESD at Tarbert and Ardrshaig have been implemented at Dhu Loch to minimise the risk of disruption to final commissioning and hand over. Fine raw water filters have been installed to minimise the risk of organic plant material entering the process which caused blockages to contactor vessel inlet distribution pipework at Ardrishaig.
Black Esk and Winterhope WOA Progress
February 2024
At Black Esk, ESD is constructing a new 2 megalitre clean water tank for Scottish Water, based at Southwoodhead Farm near Kirkpatrick Fleming. We are using R H Irving as our main civils sub-contractor to carry out all elements of construction other than M&E. The job is challenging from both a weather and an environmental point of view: being situated at the top of a small hill with open countryside to the Solway Firth means it is very susceptible to wind and we are near Eskdalemuir, so we do suffer from the rain also. The ground consists of heavy red clay which does not settle quickly when mixed with water, so we have installed a large amount of silt ponds and silt fencing and barriers to stop dirty water from leaving site. We are currently chemically treating dirty water under licence from SEPA to allow it to be removed from site in a clean state.
Strategic Board visits Mannofield WTW
February 2024
On 1st February, the team at Mannofield welcomed the ESD Strategic Board to site to see the progress being made to date. Due to the significance of the Mannofield project within the Scottish Water portfolio of projects, everyone was keen to see the project in real time and enjoyed their tour and briefing by the team.
At the Mannofield WTW (Water Treatment Works) site, the concrete works for the static mixer chamber were completed at the end of 2023 by sub-contractor, CPR. This consisted of a 13m x 9m x 4m buried chamber RC chamber which will house the new pipe work, valves, flow meters, static mixer and sampling equipment. Challenges faced during its construction included the diversion of existing services and the installation of a cofferdam in very hard ground conditions.

Water Supply Boost for Loch Ness Communities
ESD has successfully completed work on Scottish Water’s new water treatment works at Invermoriston on the banks of beautiful Loch Ness, transforming the fresh water supply to the Glenmoriston and Fort Augustus communities. Local MSP, Kate Forbes, was on hand on 15th September to unveil a plaque and declare the new plant open.
ESD’s Chief Operating Officer, Wendy Cooper, said: “The scale and complexity of the project to give Fort Augustus and Glenmoriston a single, improved water supply for the future has always been striking. Along the way, our team has had to deal with everything from the challenging ground conditions beneath a 200-year-old wonder of water engineering to a global pandemic.
“The common factor in every stage and every challenge has been the strength of our working relationship with our partners – the local community, landowners and our supply chain. Where we have encountered difficulties, we have been able to work together to find solutions. The outcome is one that everyone who has played a part should feel proud of."
Congratulations to ESD’s Project Manager, Kelton Bennett, Senior Site Manager, Mark MacLennan, and the whole team on a magnificent achievement.
