Water & Wastewater
Water companies face intense and growing pressure. Ageing infrastructure, climate-related risks, population growth, and increasingly stringent regulation all place new demands on capital planning, while customers and regulators expect improved outcomes, greater efficiency, and full transparency.
The challenge: how to make the most of limited capital and operating budgets, while delivering measurable improvements in service, resilience, and environmental impact.
That’s where AIM delivers value.
Purpose-built for long-term planning and regulatory alignment.
AIM is used by leading water utilities to plan and prioritise investment across all asset types – from buried distribution networks to treatment works. It helps organisations justify funding decisions, meet regulatory expectations, and build robust asset strategies that align with frameworks such as the Common Framework, DWMP, Asset Management Plans, Water Resources Planning, Asset Health, and OFWAT’s regulatory price review requirements.
Instead of relying on static spreadsheets, top down analysis, or even rules of thumb, AIM enables precise, scenario-based planning at the individual asset level – combining condition, cost, criticality, and risk in a unified platform.
How AIM supports the water and wastewater sector.
Optimises asset interventions to reduce service failures, leakage, pollution, and environmental risk
Models long-term investment needs under varying budgets, policies, and performance constraints and scenarios
Builds regulator-ready business plans with full transparency, traceability, and justifiable assumptions
Quantifies risk and value across options - enabling defensible trade-offs between cost, service, and carbon
Supports strategic and tactical planning from 40-year investment programmes to short-term delivery optimisation
Adapts to changing landscapes - including climate change, stakeholder expectations, environmental concerns, and regulatory drivers
Incorporates uncertainty, using it to generate confidence intervals around performance and budget measures to help manage risk tolerances, climate change, financial exposure, and the value of data improvement
"AIM has maintained itself at the forefront of innovation and we are continually impressed by the flexibility, power, and speed of AIM.
From becoming a first adopter in 2011, we have now significantly expanded the use of AIM to nearly all our asset base, including Trunk Mains, Distribution Mains, water resource planning, wastewater infrastructure (1.3 million assets) and above ground non-infrastructure assets."

Infrastructure Planning Manager, Thames Water
In use: Planning across the full asset base
From water mains to pumping stations, AIM helps planners understand when, where, and how to invest. Teams use it to develop long-term plans, stress-test scenarios, and ensure that investment aligns with customer outcomes and regulatory drivers.
Utilities like Thames Water and South West Water have embedded AIM into their business-as-usual planning cycle using it to, amongst other applications, build AMP7 and AMP8 investment plans, and manage trunk main renewal programmes.
AIM enables
- Confident investment planning under uncertainty
- Clear, evidence-based decision-making
- Improved resilience and reduced risk exposure
- Better outcomes at lower whole-life cost
Whether you’re building your business plan, defending it to stakeholders, or delivering it in practice – AIM gives you the insight and control to do it better
