15 Year Action 1998 Take-over from Polymetrics Actions: Excessive valve throttling, non-matching duty points, pumps leaks, Well pumps to drain!! 2001 Installation of Pelton Turbines 2004 Pressure exchangers replaced Francis Turbine pumps. Energy recovery efficiency 2009 Upgrading of desalination plants SCADA system, energy recovery pumps and membrane replacement (i.e. 75% of membranes). (EU pre-accession funds) 2010 Installation of VFD pressure optimisation and better control 2016 Replacement of 25% of membranes, pressure exchangers, and replacement of pumps
