Utility Deploys Advanced Technology Across Its
Network to Accelerate Progress Towards Net Zero Emissions
Scottish Water has made a big dent in its greenhouse gas
emissions by deploying advanced technology at 200 pumping stations
across its network. By combining high-efficiency pumps and advanced
digital technologies, the utility has reduced energy consumption by
up to 60%, accelerating its goal of becoming carbon neutral by
2040.
As Scotland's publicly owned water supplier, Scottish Water
provides essential water and wastewater services to more than 2.6
million homes and 150,000 business premises across Scotland. Its
pump stations move water across a large geography, including remote
villages and islands, so the utility was challenged to keep energy
consumption and emissions down.
In collaboration with leading global water technology company
Xylem (NYSE: XYL), Scottish Water began trialing a smart pumping
solution at two pilot sites, Maple Grove and Cross Dene. The trial
delivered pronounced cost savings, including a 99% reduction in
unplanned maintenance and a 40% reduction in energy, prompting the
utility to adopt the technology across its network.
“Moving and treating wastewater is incredibly energy intensive.
Around 17% of transport emissions in Scotland are from the water
and wastewater operations sector, so anything we can do will have a
big impact for both Scottish Water and the country,” Nathan Wield,
Wastewater Operations West Manager for Scottish Water, said. “By
deploying smart technology, we can prolong the lifetime of our
equipment, prevent callouts, and reduce downtime, so there is less
service disruption and reduced risk of environmental impact. This
delivers real cost savings for the Scottish people and gives us a
major boost in our work to reduce our impact on the climate.”
A pioneer of digital innovation, Scottish Water combined several
Xylem technologies – Avensor monitoring and Flygt Concertor
intelligent pumps – to deliver the cost and energy savings. The
utility now has real-time visibility and control across its
network. Remote monitoring has enabled the Scottish Water team to
replace weekly callouts with monthly inspections.
As a result, the utility saved more than 400,000 miles of
reactive travel and 37,000 liters in diesel consumption, reducing
its annual carbon output by 160 tCO2e.
“Reducing greenhouse gas emissions across the water sector
presents a unique opportunity to rethink water management. New
approaches and advanced technologies can help water utilities go
further, faster,” Ian Thompson, Xylem Vice President UK &
Ireland, said. “Innovative utilities like Scottish Water are a
prime example of what can be achieved by harnessing the power of
digital to decrease the sector’s impact on the environment – and
still deliver a resilient, cost-effective, and reliable service for
communities.”
Scottish Water also deployed advanced monitoring systems to
extend the life of critical assets, including a main pipeline that
runs more than 10 miles from the Blairlinnans Water Treatment Works
to a reservoir in West Dunbartonshire. Using Xylem’s SoundPrint
Acoustic Fibre Optic System – the first of its kind in Europe –
Scottish Water carried out extensive inspections of the pipeline,
allowing the utility to reduce the possibility of failure by
proactively maintaining areas found to be at risk.
Data from the inspection showed that only 2% of the pipeline
needed maintenance attention. Scottish Water achieved significant
cost savings by extending the life of the remaining pipe sections
resulting in fewer disruptions to customers. That approach to
monitoring and targeted maintenance also further reduced the
utility’s greenhouse gas footprint by avoiding emissions associated
with unnecessary pipeline replacements.
