Annual Report

To highlight what we do, each year BIAPWS produces an annual report summarising our activities, achievements and events.

The full report for the year to June 2018 can be downloaded here




The British and Irish Association for the Properties of Water and Steam (BIAPWS) is the UK and Ireland national committee of the International Association for the Properties of Water and Steam (IAPWS) and the representative body for Power Plant Chemistry in the UK and Ireland. BIAPWS is a not for profit organisation. This is the annual report of the activities of BIAPWS for the period from August 2017 to July 2018. A list of publications by BIAPWS members during this period is included in Appendix A.

BIAPWS membership remains strong, with current support provided by twenty-three industrial sponsors, six honorary members, five ordinary members and eleven corresponding members.

BIAPWS committee meetings are held three times a year and attendance at these continues to be good, typically with around thirty people present. A recent change has been to expand the technical sessions at BIAPWS committee meetings to add value to meeting attendance. Industrial member’s representatives are able to bring a colleague to the meetings to benefit from and contribute to the discussions.


Each year, BIAPWS organises an annual symposia on power plant chemistry and water treatment. The 19th in this series of symposia was held at the University of Warwick, Coventry, on 26 – 27 June 2018. The symposium consists of introductory sessions on the fundamentals of power plant chemistry and water treatment, followed by more detailed technical presentations. The event remains well supported, with around 80 delegates and 11 exhibition spaces taken up in 2018. A copy of the symposium programme is included in Appendix B. A paper summarising the proceedings of the 2018 event has been published in Power Plant Chemistry journal.


BIAPWS has continued to support IAPWS through its formal membership and participation in IAPWS activities. A number of BIAPWS committee members are represented on IAPWS working groups. At the 2018 IAPWS annual meeting in Kyoto, Japan, BIAPWS will be represented by M. Sparrey and Adam Caswell of EDF and Paul McCann of Uniper. In addition, BIAPWS is represented on the executive committee of IAPWS.


BIAPWS offers selected sponsorship opportunities for student placements and schools events that aim to raise the awareness and generate new interest amongst students in the areas of science and technology relevant to the properties of water and steam, including power plant chemistry. This initiative has in the past proven highly successful, with many previous winners of the BIAPWS Student Award going on to full time employment in power generation.

Over the last 12 months, BIAPWS received no opportunities for sponsorship in 2018


The public facing pages aim to promote a better understanding of what BIAPWS and IAPWS are and what our activities include. The members area now includes a library of technical information for our members from BIAPWS meetings and symposia. Further developments are planned to include training resources.


BIAPWS is currently represented on the three British Standards and Euro Norm Committees listed below of relevance to power plant chemistry and water treatment. However, there have not been any significant developments in recent years.

  • PVE/2: Water Tube and Shell Boilers. The UK standards committee has responsibility for BS EN 12952-12:2003: “Water-tube Boilers and Auxiliary Installations - Requirements for Boiler Feedwater and Boiler Water Quality” and BS EN 12953-10:2003: “Shell Boilers - Requirements for Feedwater and Boiler Water Quality”.
  • CII/62: Treatment of water for boilers. The UK standards committee also has responsibility for BS 2486:1997: “Recommendations for Treatment of Water for Steam Boilers and Water Heaters”.
  • EH/3/6: Water quality - sampling. The UK standards committee is responsible for BS 6068-6.7:1994 (ISO 5667-7:1993): “Guidance on Sampling of Water and Steam in Boiler Plants”.


BIAPWS maintains correspondence with a number of professional bodies with the aim of sharing information and closer working.

  • BIAPWS is represented on the Energy Sector Interest Group of the Royal Society of Chemistry by John Greene;
  • BIAPWS is also represented on the Water Science Forum of the Royal Society of Chemistry by Eric Huff;
  • Richard Hill, who is a committee member of the Institution of Chemical Engineers (IChemE) Water Subject Group, is also a Corresponding Member of BIAPWS.
