Whole-system planning for resilient water infrastructure
Better decisions across the whole water system.
Explore. Compare. Adapt. Decide.
One connected journey from understanding the system to committing to a plan you can defend.
Explore
Understand the system, constraints, dependencies and possible futures.
Compare
Test options and scenarios across cost, performance, risk and outcomes.
Adapt
Update plans as assumptions, priorities and conditions change.
Decide
Make transparent, defensible decisions with a clear understanding of trade-offs.
Applications of .water
Planning each part of the water system separately cannot answer the questions water companies are now being asked. These applications bring the whole system into one adaptive model.

Asset Planning
Capital Investment & Asset Planning
Prioritise capital maintenance and enhancement spend across the asset base, linking risk, condition, criticality and customer outcome in a single auditable framework.
Network Optimisation
Leakage Strategy & Network Optimisation
Identify, target and sequence leakage intervention spatially and temporally to meet regulatory targets at minimum whole-life cost.
Wastewater Planning
Storm Overflow & Surface Water Management
Model the cost, benefit and sequencing of overflow improvements across the sewer network, demonstrating regulatory and environmental compliance.
Resilience Planning
Water Systems Planning & Resilience
Develop adaptive Water Resource Management Plans under multiple climate and demand scenarios, testing supply-demand balance robustly.
Business Planning
Business Planning & Regulatory Investment
Construct evidence-based, outcome-linked PR submissions connecting asset need, investment cost and ODI performance to a coherent customer-funded programme.
Environmental Planning
Environmental Programme Planning & Delivery
Optimise WINEP and NEP delivery schedules, balancing environmental improvement obligations against capital efficiency and operational readiness.
Connect capital investment, operational performance, environmental compliance and customer bill impact into one adaptive model - enabling water companies to build, test and defend a holistic PR strategy that holds up under Ofwat scrutiny and evolves through the AMP cycle.
How .water works
Temporal, Spatial & Financial Planning

- 97% net carbon emission reduction by 2045
Scottish Water - Dalmuir Wastewater Catchment Strategy
Rapid whole-system scenario analysis helped Scottish Water compare competing investment choices across one of Scotland’s most complex wastewater catchments.
- 20 scenarios modelled and compared to 2050
- 25-30% Opex reduction from an MBBR treatment upgrade
- 35% catchment removal needed to match the same savings
WASTEWATER
Helping Scottish Water identify the right long-term investment strategy for Dalmuir
Rapid whole-system scenario analysis helped Scottish Water compare competing investment choices across one of Scotland’s most complex wastewater catchments.
The challenge
How do you know which intervention will deliver the greatest value across an entire wastewater system?
The Dalmuir wastewater treatment works (WWTW) catchment serves a large area of Greater Glasgow and faces increasing pressure from population growth, climate change and environmental obligations.
Scottish Water needed to make a strategic choice. Should flows be redirected away from Dalmuir WWTW? Should the treatment process itself be upgraded? How much difference could investment in SuDS make? And what would each choice mean for operational expenditure, CSO spills, sewer flooding and the wider Bioresource Strategy?
Answering those questions meant looking beyond individual assets and understanding how different investment choices would interact across the catchment.
The solution
Rapidly comparing fundamentally different investment choices at whole-system level
Using Decisio™ Wastewater Systems, BMA created a connected digital representation of the Dalmuir catchment and rapidly tested alternative future configurations.
Twenty scenarios were compared, combining different catchment configurations with alternative treatment-process choices. Decisio also identified and quantified potential SuDS interventions across 20 priority drainage zones.
This allowed Scottish Water to see not only what each intervention could achieve individually, but the trade-offs between fundamentally different investment strategies.
The impact
Greater confidence in where investment can make the biggest difference
The analysis established MBBR as the clear strategic priority for Dalmuir.
Across the scenarios modelled, the MBBR upgrade consistently reduced operational expenditure by 25-30%. The analysis also showed that SuDS could play an important supporting role, while catchment reconfiguration alone would not solve Dalmuir’s CSO spill and sewer-flooding challenges.
By bringing these choices together, Scottish Water gained a clearer evidence base for its long-term catchment strategy - and greater confidence in where investment could deliver the greatest value.
Looking at the whole system
Looking at the whole system changes the investment conversation
The Dalmuir case study shows why wastewater investment decisions cannot always be made asset by asset.
When planners can rapidly compare different interventions across the wider system, they can test assumptions, understand trade-offs and identify where investment is most likely to deliver the outcomes they need.
