Large Water & Waste Infrastructure Oversight Lead

We are Ofwat, the Water Services Regulation Authority, a non-ministerial government department responsible for regulating the water sector in England and Wales.

We have an opportunity for a Principal Large Water & Waste Infrastructure Oversight Lead to join our Water Supply Team within RAPID & Environmental Planning Directorate.

The water sector is entering a new chapter. The government has set out a bold new direction, bringing together expertise from across the sector to deliver better outcomes for customers and the environment. We are collaborating with fellow regulators to respond to recommendations in The Independent Water Commission Report, the Welsh Government’s response to the Green Paper, Shaping the Future of Water Governance in Wales, and the Government’s White Paper, A new vision for water.

Ofwat is working with the government and other regulators to help create a new body for England, bringing together our strengths with those of the Drinking Water Inspectorate, the Environment Agency and Natural England. We are also continuing to work with the Welsh Government to support decisions on the future arrangements for Wales.

While these changes take shape, our mission remains the same: to hold water companies to account, drive performance, and ensure the sector delivers real value for customers, communities, and the environment. If you’re passionate about making a difference, this is a unique moment to join us and help shape the future of water, and together we can continue to make a positive impact.

You can find out more about why you should join Ofwat, our strategy, values and our framework for success in the attached Information for Candidates Pack.

We're looking for a Large Water & Waste Infrastructure Oversight Lead to join our Water Supply team within the RAPID and Environmental Planning directorate at Principal level. The sector is facing unprecedented challenges, and we want someone who relishes the opportunity to apply their skills and experience to improve our water environment. Whilst there are specific policy areas you will lead on, you will also play an important role in driving the collaborative work programme across Governments and with other regulators to improve future water resources management.

The Large Water & Waste Infrastructure Oversight Lead role has an important and valuable contribution to enable us to deliver on our goals and regulatory commitments. Primarily, you will lead the large scheme gated process and our oversight of development of large water and wastewater schemes within it. These complex schemes received funding at the 2024 price review and are required to address the growing challenges the industry faces.

The gated process you will lead ensures their timely development continues to demonstrate technical feasibility and cost efficiency for customers and the environment. To achieve this, you will lead our strategy for engaging and building relationships with water companies and their programme delivery and technical teams, wider governments, regulators and a varied range of stakeholders. You will also lead on policy decisions within the process and develop policy to shape its ongoing evolution.

Your role may also cover areas such as the Asset Improvement Process – coordinating the process and bringing together engineering, asset management, economics, assurance and regulatory stakeholders to identify, develop and justify investment programmes for Ofwat funding. You will also work to align technical and programme insights across dependant regulatory processes and teams. This includes technical planning processes, such as water resources management plans (WRMPs) and drainage and wastewater management plans (DWMPs), as well as economic and delivery processes, including future price reviews, cost change processes, delivery plans and price control deliverables (PCDs).

Key deliverables:

In this role you will be expected to:

• Lead the large scheme gated process, including leading on policy decisions within the process for investment communication and programme delivery.
• Lead on our technical and engagement steer of the large scheme gated process, including advising on engineering issues and building relationships with water companies and their programme and technical teams, and wider regulators.
• Lead and support on other areas of cross-process and cross-regulatory work to align decisions across partner regulators and delivery frameworks, including asset improvement processes, WRMPs, DWMPs, business plan links, cost change processes and PCDs.
• Manage a team of scheme leads and supporting specialists, including directing on key milestones and timelines, programme requirements and training.
• Contribute to the RAPID and Environmental Planning directorate strategy and the Price Review directorate more broadly as required.

Assessment process

Sift Stage - Blind Sifting

We operate a blind sifting model to eliminate bias. All candidate identifying information will be removed from applications.

At sift stage we will assess your application (CV and personal statement) against essential criteria 1, 2, 3, and 4 listed below. Please ensure you provide enough evidence in your application form to demonstrate how you meet the criteria.

Use your personal statement to address the below criteria and tell us how your experience, skills and knowledge meet them:

• Lead criterion: Relevant technical experience within engineering, science, capital programmes, asset management and/or business planning, working at a senior level, ideally within the water industry.
• Academic or professional experience of wider environmental issues and good knowledge/understanding of those related to the water industry.
• Experience of policy development and implementation, and/or designing and delivering programmes of work or processes within a relevant field.
• Significant experience of building and maintaining constructive working relationships with internal and external stakeholders, influencing decisions and delivering outcomes across organisational boundaries.
• Please note that in the event of receiving a large number of applications, a pre-sift may take place on just the lead criterion.
• * If a high volume of candidates meet the minimum pass mark at sift stage, we will only progress the highest scoring candidates to interview. Candidates not invited to interview, who have achieved the minimum pass mark, will be placed 'on hold' until the final stage of the assessment process is completed. Should the role/s remain unfilled, candidates placed 'on hold' may be invited to interview in merit order.

Feedback will only be provided if you attend an interview or assessment.

Interview Stage - Transparent Interviews and Presentation

At interview stage we will test against essential skills, experience, knowledge and attributes set out above.

Our transparent interview process involves candidates receiving a selection of attribute-based questions in advance. This has been proven to help neurodiverse candidates and others to perform better at interview and is part of our inclusive culture.

You can read more about attributes and our Framework for success here.

Please note that the interviews will be conducted via video conferencing software (Microsoft Teams).

As part of the interview process, we will require a short presentation. Further details will be provided to candidates upon invitation to interview.

Please ensure anything you present in your interview answers is factually accurate, and you are not presenting the ideas and experience of others, or generated by AI, as your own. You may expect follow up questions.

It may be necessary for a second stage interview, which will be communicated to the successful candidates, if required.

If the assessment process identifies more appointable candidates than roles available, a reserve list will be created for 12 months from which further appointments in merit order can be made.

'Near-miss' candidates (candidates who have performed well at interview stage but haven’t scored high enough for the advertised Principal band) may be considered (in merit order) for a Senior Associate grade post – a band lower than Principal. Further details will be provided to candidates as needed.

If you have any queries about any aspect of this role, selection process, or you require any reasonable adjustments, please email recruitment@ofwat.gov.uk.
