How have these improvements been
possible?
Telemetry systems rationalised
Hydrometry and Telemetry activities were combined
Hydrometric data management systems rationalised
National and Regional H&T Panels
Low benefit sites challenged and closed.
Implementation of a risk based approach
Adoption of new flow measurement technology

Future challenges
Meeting changing business needs
Reducing the environmental impact of our activities
Increasing efficiency i.e. doing more for less

Overall our workforce will reduce from 11,400 FTEs today to somewhere in the region of 10,000 by October 2016.
FCRM GiA is likely to reduce by around £12.5m from 2013/14 to 2015/16.
