Why the Water Sector is Entering a New Phase

The UK water sector is entering a period of significant change. The Government has already committed an investment of £104bn to transform water infrastructure between 2025-2030, alongside regulatory action through the Water (Special Measures) Act 2025. These steps have begun to address some of the long-standing challenges faced in the water sector and highlight the scale of transformation that is required. 

The publication of “A New Vision for Water” marks the next stage in this process and is based on recommendations from the Independent Water Commission’s final report. The water white paper outlines the government’s intention to reshape the water sector around long-term outcomes, introducing a model of “preventative regulation” designed to identify and tackle risks early, before they develop into wider problems. 

This decisive shift in how the sector will be governed and delivered, will better align the sector towards shared outcomes: better protection of public health, improved environmental performance, stronger economic contribution, restored trust and transparency, and water and wastewater services that are reliable and effective for all stakeholders. 

The Reform Themes in “A New Vision for Water”

The white paper is structured into 7 reform themes that are designed to address aspects of performance and delivery within the water sector and the wider water system to make sure it delivers on the most critical outcomes.

A New Direction for Water: The reforms aim to establish a clearer long-term direction for the sector. This includes reforms to Strategic Policy Statements, rationalising plans, creating a more joined-up regional water planning function and introducing a long-term stability objective. An upcoming transition plan will support these changes by improving efficiency in long-term planning and providing a clearer framework for delivery.

Resetting Regulation: A new integrated water regulator will be introduced to provide greater stability, transparency, and an integrated view of both economic and environmental performance. This will be supported by a new supervisory approach, making regulation more proactive, more targeted to individual company performance and more focused on early intervention. The new regulator will help to:

• Help underperforming companies recover faster
• Attract the investment they need
• Improve financial resilience
• Strengthen asset health
• Improve environmental outcomes

Attracting Investment: A key priority is to make the water sector more attractive and reliable for investors seeking stable and fair returns. The policy outlines ways in which this will be achieved as:

• Rationalising and simplifying performance commitments to reduce volatility in returns.
• Introducing measures to improve financial resilience
• Increasing competition through innovative third-party financing
• Reforming the appeals process to align the water sector with other utility sectors
• Resetting the balance of risk and return for investors.

Collectively, these measures aim to support a long- term and stable investment in water infrastructure.

Putting Customers First: The reforms place a strong emphasis on customer protection and public health. The White Paper outlines the creation of a new independent water ombudsman, stronger safeguards for drinking water and an increased focus on public health outcomes as key measures to achieve this objective.

Clear Action for Clean Water: “A New Vision For Water” builds on existing investment in storm overflows and wastewater treatment whilst introducing further measures to improve environmental performance. These measures include, tackling sewage misuse, introducing a single set of stronger and clearer standards, strengthening enforcement for agricultural pollution and implementing an open monitoring system to remove companies self-reporting on their own environmental performance. These reforms will support the government’s commitment to achieving cleaner rivers, lakes and seas.

Water Security: Water security is set to be achieved through a combination of infrastructure, efficiency and regulatory reform. Key actions include:

• Improving asset health through new mapping and statutory resilience standards
• Reducing leakage
• Increasing water efficiency with more water reuse, smart metering and innovative regulation

The reform also aims to streamline infrastructure delivery through new planning systems, provide support to strengthen supply chains and improve regulatory oversight to protect infrastructure from growing risks.

Transition Plan: A transition plan is due to published this year and will guide the implementation of these reforms. It will be based on the following principles:

• A clear and straightforward roadmap
• Clarity on roles and responsibilities
• Securing buy-in from regulators and the water industry
• Practical guidance on creating capacity
• Robust governance processes.

This transition will be led by the government in partnership with existing regulators, companies, investors and environmental organisations.

What these Reforms Mean for Real Projects

The “A New Vision for Water” white paper is framed around policy and regulation, but its success will ultimately be measured on site, in how projects are specified, delivered and handed over. 

For water companies and Tier 1 contractors, the implications are practical and immediate. 

A more integrated regulatory model and clearer standards should reduce ambiguity at the front end of projects. But this also raises the bar. Specifications will need to be clearer, more consistent and more aligned to long-term outcomes, not just minimum compliance. 

At the same time, the shift toward preventative regulation and asset health places greater emphasis on reliability, repeatability and performance over time. This is where many projects have historically struggled. Issues such as late design changes, inconsistent specifications, site readiness gaps and coordination challenges between delivery partners remain common causes of delay and inefficiency. 

In this context, the reforms are not just about doing more work, they are about delivering work differently. 

Projects will increasingly need to move away from one-off, bespoke approaches and towards models that support

• Standardisation across programmes 

• Earlier design alignment between stakeholders 

• Greater use of offsite manufacture 

• Stronger coordination across supply chains

• Faster, more predictable installation and commissioning

The organisations that succeed will be those that can translate regulatory clarity into delivery certainty, reducing friction between design, manufacture and site, and removing the all-too-familiar pain points that slow projects down. 

In short, joined-up regulation will only deliver value if it is matched by joined-up delivery.

How Colloide Can Support

As the sector moves into this more structured and outcomes-driven environment, the role of the supply chain becomes even more critical. 

At Colloide, our focus is on helping utilities and Tier 1 contractors turn policy intent into practical, deliverable solutions, particularly in areas where projects often encounter avoidable friction. 

With over 20 years’ experience in water and wastewater engineering, we support the full project lifecycle, from design and manufacture through to installation, commissioning and maintenance. 

But more importantly, our approach is built around addressing the challenges that repeatedly impact delivery: 

Ultimately, the direction set out in “A New Vision for Water” is clear: better outcomes will come from better alignment between regulation, planning and delivery. 

Our role is to help make that alignment work in practice, removing common pain points, improving efficiency on site, and supporting the delivery of resilient, high-performing water infrastructure.
