Working within a small team of network water quality scientists, you will engage with operational teams in the field as well as carrying out office-based projects and activities.  In doing this, you will ensure the protection of public health and deliver excellent customer service.

A primary focus will be ensuring appropriate investigation of water quality failures, events and complex customer complaints take place.  This will involve determining the root cause and proposing appropriate measures to mitigate identified risks, thereby reducing the likelihood of future recurrence.  For network water quality events, you may also be required to take on the role of an event scientist, providing advice regarding the protection of public health and compliance with drinking water regulations.

The team play a pivotal role in governance relating to the operation and maintenance of the distribution system.  You will be involved with maintaining up to date operational network standards, for example, associated with the disinfection of water mains.   Additionally, you will be involved in reporting on performance and risk to ensure appropriate investment and continued compliance with water quality requirements.

Key areas of responsibility will include:

  • Investigate failures of network water quality parameters and complex/long running customer complaints.
  • Act as an event scientist for network water quality events providing advice regarding the protection of public health.
  • Participate in Drinking Water Safety Plan audits and risk assessment updates.
  • Review permit to work requests, providing water quality approval as appropriate.
  • Provide technical input to relevant Water Network Asset Standards, relating to the disinfection and flushing of water mains.
  • Establish relationships with internal stakeholders to promote the protection of public health, ensure appropriate network investment and continued compliance with water quality requirements.
  • Develop technical expertise in the field of drinking water quality and clean water distribution systems and apply and communicate this knowledge.

To be successful, you will have the following skills and experience:

  • Degree / HNC in a relevant scientific discipline.
  • An understanding of the current legislation, regulatory and operational requirements surrounding water quality would be advantageous.
  • Experience in the field of drinking water quality, risk and project management.
  • Highly developed communication and interpersonal skills.
  • Significant competence with the use of complex IT systems and standard office software.
  • A basic knowledge of GIS would be advantageous.
  • Travel to other sites is a requirement of the role and therefore a full driving licence is required.

What’s in it for you?

This is a great opportunity to work as part of a specialist team of water quality scientists responsible for protecting public health within the clean water distribution system.  This will be achieved by ensuring standards are set correctly; risk assessments conducted; failures, events and customer complaints investigated rigorously; and appropriate measures delivered to mitigate risk.
