We are pleased to announce the publishing of the fifth FWR newsletter under IES editorialship. This issue looks at one wastewater treatment plant taking a step towards carbon neutrality, a water policy Q&A with the IES Policy Lead, and provides an update on the FWR's Review(s) of Current Knowledge (ROCKs). The articles in this issue uncover the potential uses of digital twins, and resources for water professionals that can lead to better policy engagement.

IES members and non-members are both encouraged to sign up to the FWR newsletter, in order to keep up-to-date with key developments in innovation in the water sector, and discover new opportunities from cross-disciplinary researchers and industry professionals. We welcome proposed article contributions for upcoming issues of the newsletter, which can be sent at any time to publications@the-ies.org.
