EPSRC PhD Studentship in: Investigating the impact of biofilms on drinking water microbial compliance

University of Sheffield - The University of Sheffield, Sheffield Water Centre in collaboration with Severn Trent Water, Dŵr Cymru Welsh Water, Scottish Water and the Centre for Doctoral Training in Water Infrastructure and Resilience

Qualification Type: PhD
Location: Sheffield
Funding for: UK Students, EU Students, International Students
Funding amount: £21,000
Hours: Full Time
Placed On: 9th February 2023
Closes: 27th March 2023
 

Start Date: 25th September 2023 (contract duration 4 years)

This interdisciplinary PhD will combine engineering and biology, advancing understanding of biofilm dynamics and interactions with bulk-water to improve resilience of drinking water systems and microbial water safety.

The PhD will specifically study sample lines, the narrow pipes that transport water from the main water supply to the tap where regulatory samples (used to monitor water quality) are collected. This research will examine the potential for biofilms to be a source of regulatory target organisms (and other pathogens), causing bacteriological exceedances in samples when mobilised, which would be unrepresentative of the actual bulk-water quality. Current biofilm management strategies lack a scientific basis, resulting in a reluctance to modify operational procedures due to fears of exacerbating the situation.

Ensuring sample lines are designed and operated to mitigate impacts of biofilms will eliminate false positives (which have significant implications, ensuring resources are better distributed to investigate true exceedances, protecting water quality and public health.

Working within a dynamic and supportive research team of industrial and academic collaborators, the research will involve:

  • Combining laboratory work using full-scale facilities at The University of Sheffield with fieldwork (with project partners, costs covered)
  • Investigating the impact of sample line design, operation (e.g. hydraulics) and final water characteristics on biofilm growth and stability, to develop evidence-based management and sampling strategies
  • Furthering understanding of biofilm ecology, including providing insight into coliform and biofilm dynamics to advance root cause analysis of bacteriological failures
  • Providing an evidence-based approach to determine and evaluate the role of sample line biofilms in bacteriological exceedances
  • Informing guidance on optimal sample line design, operation and management to mitigate biofilm impacts on regulatory samples

This is an exciting opportunity for motivated individuals to contribute to world-leading, applied biofilm research and inform practices within the water sector.

The PhD programme benefits from being part of the EPSRC Centre for Doctoral Training in Water Infrastructure and Resilience (CDT WIRe). CDT WIRe is a collaboration between the three leading UK Universities in water resilient infrastructure. Students will benefit from a bespoke training scheme delivered by world leading experts from academia and industry, access to world-leading experimental and computational facilities as well as close and regular contact with industry and end user partners.  CDT WIRe is committed to promoting a diverse and inclusive community, and offer a range of family friendly, inclusive employment policies . For further information on the CDT WIRe scheme visit the web site at:  https://cdtwire.com/

Supervision

The project will be supervised by Dr Fish, Prof Boxall and Dr Pick in collaboration with partners from Severn Trent Water, Welsh Water and Scottish Water.
