Deputy Chief Inspector (Grade 6)
Ref. 408230
Make a difference in protecting public health by becoming a Deputy Chief Inspector.
As part of the Senior Management Team, you will be responsible to the Chief Inspector for developing and managing the Inspectorate’s resources in the delivery of its Vision and Strategic Objectives.
You will be part of the strategic team delivering regulation on the quality, assurance, safety and security of drinking water supplied by the water industry and the local authorities which includes delivery of secure network information systems by operators of essential supplies for water. You would be expected to communicate effectively with, and provide technical and scientific advice to, Ministers, officials of Defra and the Welsh Government and wider government departments. Engagement with stakeholders associated with the water sector such as Water UK, UKWIR, UKHSA, Public Health Wales, RAPID, as well as the wider regulatory landscape including the Environment Agency, the financial regulator Ofwat and CCW, requires a broad understanding of the complexities of the water sector.
The Deputy Chief Inspector leads and directs experienced professionals with strong academic, technical, scientific, engineering and practical backgrounds in the water and allied industries. The Inspectorate’s technical and support staff includes experts in network information systems, data management, information and knowledge management, and business administration. The work requires a high level of expertise in all aspects of drinking water supply; the interpretation of law, fair and proportionate enforcement of legal requirements and the provision of sound advice.
The role requires someone who combines strong leadership, technical expertise and managerial skills with the judgement and flexibility necessary to operate in what can be a demanding environment. Working within the context of the respective Government policies is also critical.

Inspector – Network and Information Systems (Cyber Security)
Ref. 408233
Make a difference in protecting public health by becoming a Network and Information Systems Inspector.
The Network and Information Systems Regulations (NIS) (2018) extended the original Drinking Water Supply regulations to include greater emphasis on the security and reliability of information systems which control drinking water production or delivery, with particular regard to the modern-day threat of cyber security.
The main responsibility of the DWI NIS team is to ensure that the 17 drinking water companies in England and Wales (that are currently within scope of the NIS regulations) take appropriate and proportionate technical and organisational measures to manage any risks posed to the security of their network and information systems. This includes the cyber and physical security of assets on which their essential service of drinking water provision relies.
The Inspectorate regularly needs to respond to an evolving risk picture, or incidents which impact on the water network. Therefore the post holder will need to be flexible and able to adapt quickly to changing work priorities and may be required to participate in the Inspectorate’s response to a security incident. This may include out of hours working on occasion, but the Inspectorate makes every effort to allow for individual personal circumstances and offers a range of flexible working options including remote working and some working from home.
