Claire Pollard CSci , Vice President Science, on Professional Registration  

I became a Chartered Scientist in 2013 when the Institute of Water first introduced professional registration for scientists. I studied Marine and Freshwater Biology as a first degree but was first introduced to the water industry when my father started working at a local Water Treatment Works and I assisted in the laboratory at the works every summer holiday whilst doing that degree carrying out chemical and microbiological testing of treated water samples.    



When I left university, I started working full time for Anglian Water expanding my knowledge and experience in the world of water testing and during that time, I obtained a Masters degree in Microbiology. My career developed from that early water company experience, moving to the Drinking Water Inspectorate where I spent over 20 years working in all areas of the regulation of drinking water quality and public health. It was during my time with the DWI that I obtained the Chartered Scientist award, the attraction being that it recognised all the different aspects of being a Water Scientist by profession rather than a scientist by qualification. It felt more relevant as a reflection of my wider water industry experience and knowledge that I had gained at that time.




I have since become an assessor for all three of the scientific registration levels for both the Institute of Water and the Science Council and promoted the benefits of being registered to scientific colleagues in my last three roles, with the DWI, Anglian Water and Thames Water supporting and acting as a mentor as much as possible. Moving into a new role recently with Southern Water, I will be doing much the same with my scientific colleagues there. The benefits of registration are so important for individual scientists in the industry as recognition of their professionalism gained through experience and knowledge in whatever scientific role they are working in, but also of their passion for being part of an industry delivering a vital public health service from provision of drinking water to treatment of sewage wastewater.


For this reason, I was really honoured to be asked to become the new Vice President of Science for the Institute of Water not least as the invite came from its predecessor Robin Price, who has championed professional registration for many years not just at Anglian Water where he works but supporting other water companies to progress the registration in their own scientific teams. He will be a hard act to follow but I know there is the support from him and from others at the Institute of Water and I look forward to continuing championing the importance and benefits of professional registration.
