Climate resilience is no longer just an environmental issue — it is becoming one of the defining operational challenges facing the UK water sector.
Water companies need to make better long-term investment decisions under increasing uncertainty. Decisio helps utilities connect operational, engineering, environmental and financial intelligence to build more resilient water systems.
Resilience is built across the whole water cycle, not event by event
More than half of England is now officially in drought. At the same time, population growth, ageing infrastructure and tighter environmental expectations are increasing pressure on water systems. Building resilience is no longer about responding to isolated events — it requires integrated planning across the entire water cycle.
Resilience runs on two clocks
Resilience gets used to mean several different things in the same conversation — redundancy, storage buffer, recovery time, supply-demand headroom, asset reliability, adaptive capacity. These rarely move together, and people around the same table are often optimising for different ones without realising it. There is also a distinction worth drawing out: reducing the chance a risk materialises is not the same as improving how the system copes when it does, and the two lead to very different investment decisions.
Much of this comes down to timing. Day-to-day resilience — storage, alternative routes, recovery time — is almost entirely bought by decisions made years earlier: the trunk main route chosen, the headroom left at a works, the mains renewed a decade ago. Long-term investment choices are only justifiable by reference to how the system performs day to day. In practice, these sit with different teams, on different cycles, and get handed between one another in a spreadsheet — which is exactly where the systemic view tends to go missing.
A whole-systems approach to water infrastructure planning
Whole systems digital business twin
A node-level representation of the raw water, potable water and wastewater system, including above and below ground assets and the changing long-term targets that affect them.
AI-powered investment options
Auto-generates new investment options beyond traditional planning, identifying connectivity schemes and capacity uplifts that account for real-world constraints.
Adaptive planning & scenario analysis
Tests investment pathways against thousands of possible futures to identify no/least-regret strategies and rapidly respond to evolving regulatory requirements.
Multi-stakeholder collaboration
A cloud-based platform with interactive dashboards and GIS mapping, bringing engineering, finance and regulatory teams onto the same page for board-level assurance.
