Northumbrian Water Group’s Head of Innovation, Angela MacOscar and HP Nanda, Divisional CEO (Water Utility) at global water and pump solutions company Grundfos have shared their predictions for the water sector in 2023.

Sharing her thoughts on what technology, approaches and behaviours will be making waves in innovation over the next 12 months, Angela MacOscar says inclusivity, energy-saving technology and citizen partnerships are set to become the biggest innovation trends for 2023, commenting:

"The global water sector is pulling together to tackle the huge challenges we share. For 2023, we now need to up the pace of putting ideas into action to start seeing the benefits.

“Watch this space, because I think that 2023 is going to be very exciting.”

The water company, which is leading the way when it comes to innovation in the industry thanks to its now globally recognised Innovation Festival, uses a design sprint model and format to create innovative outputs to help improve services for its customers and bring fresh ideas to the utilities sector.

According to the North East Innovation expert, the top innovation trends to watch out for are:

1. Citizen partnerships

We will see a change in conversation with our customers, moving to more of a partnership with trust and shared responsibility on some of the important challenges where they hold the key – such as flushing wipes that cause blockages, water efficiency in the home and keeping our bathing waters in tip-top condition. At Northumbrian Water, our Bin the Wipe campaign has already seen great results in blockage reduction by working hand in hand with our customers. We also have a number of projects in the pipeline that will engage customers in new ways to develop this partnership on things such as lowering their water usage and boost environmental interest.

2. Sustainable and circular solutions

Our water and wastewater treatment processes emit a number of valuable by-products that can and must be recycled. Long-term impact and sustainable solutions need to be at the top of the list for any new project, we need new business models to make these options the go-to choice. Northumbrian Water has already secured OFWAT funding to explore the capture and re-use of phosphorus and a scheme to capture ammonia to create hydrogen fuel. These projects will be well under way in 2023 and you will see much more of this as the year unfolds.

3. Energy and chemical efficiencies

Need drives change, and this year we have seen unprecedented increases in energy and chemical costs. This has prompted action to tackle these costs, so expect to see many radical new solutions and different approaches to be taken to manage these costs and make our processes more efficient too. At Northumbrian Water we seize the opportunity to do things differently and this challenge presents the opportunity to re-write how we operate our treatment plants, and we are pulling out all the stops!

4. Smart sewers and environmental monitoring

To have the best rivers and beaches, we need to leverage technology so we can better understand water quality in our environment. This is a very tough challenge to crack. There are some brilliant technologies available that do the job well, but it is not viable to deploy them at the volume required across our > 50,000km networks. We are working on some exciting projects that are exploring new ways of getting the data needed, and new ways of sharing this information with our customers and bathing water users. Expect to see some big news on this in 2023.

5. Inclusive innovation

Innovation is a team sport in Northumbrian Water and there is a need to make this a place that is inclusive for all so that an innovative culture can truly thrive. If this is not done, and only a small number of people are involved, the potential lost is huge. At Northumbrian Water we have been working hard to bring this alive at our innovation festival and in our workplaces. We have looked at quiet innovation, how we can create design sprints that include all preferred styles of participation and thought processes – which has included slowing down the sprint activities, allowing space for meaningful reflection and quiet spaces. We have also explored diversity and inclusion and neurodiversity as we strive to innovate with purpose with all our employees and partners.

6. No Dig solutions

Annually the utility sector digs more than a million holes in the road which causes disruption to our customers and can be a costly solution. Everyone has been searching for innovative solutions in this space. At this year’s festival we unveiled a technology we are working on with Origin. This game changing, mineral based solution reduces the need for excavation and has been successfully applied to a number of live trials in 2022. We will be developing this solution further for the water sector during 2023.

7. Open AI

AI (Artificial Intelligence) has been in the charts for a number of years, and we are now seeing this powerful technology applied routinely across the business to fast-track learning and improve services. AI will become more prevalent in 2023 with natural language processing and machine learning advances and improvement in its understanding of us and ability to perform more complex tasks. Open AI is available to everyone in the form of ChatGPT. It is a sophisticated artificial intelligence system, made by the Microsoft Corp., that responds to complex queries with the appearance of striking intelligence and accuracy. It does have rules but could easily be mis-used as it is able to create very plausible human responses. Like with all new technologies the full power is still to be realised but the learning curve with millions of users will be very steep and will develop uses we can’t even imagine today. AI is definitely here and will be a part of everyone’s jobs and can be used to drive massive efficiency and innovation in the water sector.

8. Regulation innovation

We need regulation in this sector and water companies are working together on many of our biggest challenges as part of the Ofwat innovation competition especially so we can deliver resilient and reliant services for all our customers. In doing this we see opportunity to work with our regulators more closely to drive up performance of the whole sector that will benefit all our customers.

9. Robotics

This is not a new technology as it is applied in the water sector today for tasks such as process automation and asset health assessment. However, today the cost is a barrier and mass application has not been realised yet. This is an opportunity that we will be looking into in 2023, technology advances in this space will enable to water sector to leverage this technology more, especially for dangerous and difficult tasks in our operations and in the management of our assets.

Grundfos - decentralised networks and increased circularity of urban water systems to optimise performance

Predictions for the UK water industry in 2023 from HP Nanda, Divisional CEO at Grundfos include decentralised networks and increased circularity of urban water systems to optimise performance:

Warming weather will turn up the heat on inadequate infrastructure

Remember the sizzling summer of 2022? Well, despite the year ending with wet weather, according to the Environment Agency much of England remained in drought. Another unprecedently hot summer is on the horizon this year. Water companies need to invest now in drought-proofing measures such as identifying new water sources, making existing resources increasingly resilient, and fixing leaks in a nationwide network of 350,000km of pipes. With some of the UK’s water infrastructure 150 years old, it is perhaps unsurprising that it performs far worse than Germany and Japan in terms of leakage rates. The UK water industry has a government-imposed goal to halve leaks by 2050 but work to improve its performance must begin much sooner than that.

Decentralised networks will empower communities to solve water scarcity

Water scarcity has a more pronounced impact on very small, extremely isolated communities that cannot necessarily afford connections to distant, centralised water systems. This is bad news for regions such as Lancashire, which is 80% rural and forecast to see a water stress increase of 80% by 2040. Similarly, rural Scotland uses 20+ litres per capita more than the UK average. For these high-risk communities, decentralised water systems present a portable, scalable solution that would facilitate local water quality control and create local jobs. This year should be the year these become more common as communities become aware of the benefits.

Urban water systems will become more circular

UK communities seeking inspiration to solve their water-based challenges may also look towards nature – or specifically, the circularity of water in nature – to optimise the performance of urban water systems. As Thames Water in London approaches completion of its Tideway Tunnel Super Sewer, for instance, Londoners can expect a circular system that reduces pollution by recovering untreated water spills from the river Thames. Circular systems can also reduce waste by putting recovered water to other uses, be it biosolids for industry, fertiliser for agriculture, or district heating. As with decentralised systems, once consumers, businesses, and local governments become more aware of the benefits of a circular water economy, investment in these solutions will increase in 2023 and beyond.

Water and energy will become intertwined

The relationship between the water used in energy production and the energy used to process water, otherwise known as the “water-energy nexus”, will be key to improving energy efficiency on a national scale. By rolling out new district heating infrastructure across the UK, the Government and local authorities could make the water-energy economy increasingly circular, closing the loop so that more water is reused and less is wasted. This works because district heating diverts surplus energy from one area to areas where demand is higher, via a network of underground pipes carrying hot water. Given the benefits of using water in this way, it should not be long before adoption of district heating spreads throughout the UK.

Cities will embrace science-based targets for water security

Last year saw the C40 Cities Climate Leadership Group commit to safeguarding cities from water-related climate hazards. 2023 should be the year that London, as a member of the C40 steering committee, and other UK cities embrace science-based targets as a key means of achieving this climate-conscious goal. With climate-related flooding and drought thought to cost cities up to $194bn in damages each year, the need to improve water security could hardly be more urgent. That’s why science-based targets, such as reducing greenhouse gas emissions by 50% by 2030, will be the best way to prepare for the net-zero deadline of 2050. That hard work has to start now.
