The decisions we make today will shape the resilience of Scotland's water services for decades to come.
Climate change is increasing flood risk, putting pressure on water resources and creating new demands on infrastructure. At the same time, customers rightly expect reliable services, a protected environment and value for money.
These challenges are increasingly interconnected and require careful balance. Decisions about investment affect not only service quality and resilience, but also environmental outcomes, carbon emissions and the communities served by Scotland's water infrastructure.
As Scotland's independent economic regulator, WICS has an important role in helping the sector navigate decisions with independent evidence and analysis in the best interests of current and future customers.
Distinct roles
Scottish Water, government, regulators, customers, communities and other stakeholders all bring different perspectives and expertise. Those perspectives will not always point to the same solution, nor should they. Good decisions depend on robust challenge, evidence and informed debate.
These distinct roles are one of the strengths of Scotland's water sector.
Scottish Water plans and delivers essential water and wastewater services. Environmental regulation helps protect and improve Scotland's natural environment. Drinking water quality regulation safeguards public health. Government sets policy direction. Customers and communities help shape priorities.
WICS brings together these different perspectives, providing independent evidence, analysis and challenge so that decisions about investment and charges are informed by a shared understanding of costs, benefits and trade-offs.
This is becoming increasingly important as climate change makes investment decisions more complex.
A different way of thinking about investment
In the past, the water industry relied heavily on engineering solutions to address its challenges. These approaches remain important, but they are not always the only answer.
Nature-based solutions, blue-green infrastructure and partnership approaches can sometimes deliver better overall outcomes. Reducing flood risk, for example, may involve working with local authorities, communities and landowners alongside traditional infrastructure investment. Protecting water quality may depend on how land is managed across a catchment.
The challenge is not simply identifying solutions to individual problems. It is understanding which approaches deliver the greatest overall value when all the costs and benefits are taken into account.
Supporting long-term decision making
One of the most significant challenges posed by climate change is uncertainty.
The sector knows more investment will be needed, but it cannot always predict precisely where future pressures will emerge or how quickly circumstances may change. New evidence, technologies and opportunities will continue to emerge over time.
That is why flexibility is becoming increasingly important.
Through the Strategic Review of Charges, WICS has introduced a more adaptable approach to investment planning. Delivering on agreed commitments remains essential, but climate change also requires the flexibility to respond to emerging risks, new evidence and changing priorities as they arise.
In practice, that means maintaining accountability for delivery while creating space to adjust investment plans when doing so will deliver better outcomes for customers, communities and the environment.
A more flexible approach helps ensure resources can be directed towards the areas of greatest need and the opportunities that deliver the greatest overall value.
Looking ahead
We know that climate change will require significant investment across Scotland's water sector over the coming decades.
The challenge is deciding where investment can deliver the greatest benefit, how affordability can be balanced with long-term resilience and how different organisations can work together to achieve better outcomes.
Success will depend on each organisation playing its part and bringing its expertise to inform the decisions ahead. For WICS, that means continuing to provide the independent evidence, challenge and economic insight that helps inform those decisions on behalf of current and future customers.
