The Five Strategic Pillars
-
Architectures: Restructuring Capital Delivery for SR27 at £13.4 Billion Scale
Scottish Water's capital delivery architecture is being fundamentally redesigned for SR27. The Delivery Vehicle 4 enterprise model — valued at £5–9 billion and replacing a 12-year-old framework — shifts from transactional contracting to outcome-based collaboration, with Stantec appointed as Primary Designer. The Seafield Waste Water Treatment Works sludge investment, scheduled for construction from mid-2026 to end-2027, addresses critical capacity constraints at the facility serving 850,000 people and processing 265 million litres daily.
-
Enablement: Digital Intelligence for Demand, Asset, and Network Management
Scottish Water's Plan for Transformation established digitalisation as a core strategic driver in 2021, with the domestic smart monitoring programme generating daily water use insights from representative customer homes. Automated Meter Reading loggers for business customers on 30mm+ meters and the Delivery Vehicle 4 digital innovation mandate create a digital intelligence layer spanning demand, asset condition, and construction delivery.
-
Resolution: Net Zero 2040 and Beyond Net Zero Through Nature-Based Solutions
Scottish Water has reduced operational carbon emissions from 462,000 tonnes to 217,000 tonnes per annum since 2006/07 and committed to net zero Scope 1 and 2 by 2040. Scottish Water Horizons operates heat-from-wastewater schemes through the Noventa Energy partnership and hydropower at Whiteadder Reservoir. More than 800 hectares of peatland were restored between 2021 and 2025, while Loch Katrine woodland creation supports a broader Beyond Net Zero ambition.
-
Alignment: Tripartite Governance and SR27 Regulatory Determination
The Memorandum of Understanding between the Water Industry Commission for Scotland, Scottish Water, and Consumer Scotland formalises a tripartite accountability structure in which consumer affordability is a co-equal policy objective alongside environmental and service outcomes. The SR27 Final Determination, expected in October 2026, must resolve tension between the £13.4 billion investment case and formal affordability concerns raised during the determination process.
-
Capability Building: Workforce and Supply Chain for a £13.4 Billion Programme
Scottish Water's SR27 programme is projected to support approximately 4,000 jobs and create opportunities for 1,500 young people through the Delivery Vehicle 4 supply chain. Graduate programmes across engineering, data analytics, finance, sustainability, and science, alongside apprenticeships in civil engineering, networks engineering, and software development, are building capability for outcome-based partnering at SR27 scale.
Operational Excellence & Resilience
Scottish Water operates an integrated water network supported by wastewater treatment upgrades, catchment management, and network-wide monitoring. Performance is achieved through sustained capital delivery and active leakage management across the asset base. This is further supported by the combined sewer overflow monitoring programme targeting 3,000 high-priority monitors by end-2026. Key performance is reflected in record capital expenditure of £1.09 billion in 2024/25. This is reinforced by leakage reduction to 454 million litres per day in 2024/25.
Scottish Water's SR27 Draft Business Plan proposes £8 billion for capital maintenance and improvement and £5.4 billion for operating and essential costs over 2027–2033, delivered through the Delivery Vehicle 4 enterprise model and funded through customer charges and Scottish Government borrowing. This investment envelope is subject to the Water Industry Commission for Scotland's regulatory determination process, with the Final Determination expected October 2026.

Expert Briefing: FAQs
Scottish Water funds the SR27 programme through customer charges and Scottish Government borrowing rather than direct capital market access. This is supported by a proposed £13.4 billion programme covering £8 billion in capital maintenance and improvement and £5.4 billion in operating and essential costs over 2027–2033. This is delivered through the SR27 Draft Business Plan and the Water Industry Commission for Scotland determination process.
Scottish Water's transformation is defined by a shift to enterprise-based, outcome-led capital delivery. This is supported by Delivery Vehicle 4, valued at £5–9 billion, alongside a rise from £1.02 billion in capital expenditure in 2023/24 to £1.09 billion in 2024/25. This is delivered through the Delivery Vehicle 4 framework with Stantec appointed as Primary Designer.
Digital intelligence improves system performance by strengthening demand visibility, asset insight, and programme-level innovation. This is supported by domestic smart monitoring in representative homes and Automated Meter Reading loggers for business customers on 30mm+ meters. This is delivered through the domestic smart monitoring programme and the Delivery Vehicle 4 digital innovation mandate.
Scottish Water has committed to net zero Scope 1 and 2 emissions by 2040. This is supported by a reduction in operational carbon emissions from 462,000 tonnes to 217,000 tonnes per annum since 2006/07 and a target to produce three times its electricity consumption from renewable sources by 2030. This is delivered through Scottish Water Horizons, heat-from-wastewater schemes with Noventa Energy, and broader Beyond Net Zero land-based programmes.
