Unprecedented control and insight is now available from any of the major treatment works, area control centres, sub-control centres and from the main London Water Control Centre - the nerve centre of the entire treatment and distribution business.

This view and control anything form anywhere capability provides outstanding levels of operational redundancy. 

Architecture

The system consists of twenty eight servers distributed around the various treatment works and distribution control centres.  Eight of the servers operate in full hot standby / dual redundant mode.  Some sixty five plus clients attach to the servers and allow operational and management personnel to view and control anything over the network by way of a complex security model which is engineered to ensure operational personnel and managers profiles match the functionality available to them.  

Platform

The entire system has been engineered with the Microsoft NT/2000 platform and as a consequence delivers huge business integration benefits and considerable Operational Cost reductions.

OPIAS™ for Oracle Historian

An Aston Dane OPIAS™ for Oracle solution sits above the Supervisory Control and Data Acquisition system.  It provides two years of analogue data, alarms and events.  Operators are therefore able to call up a real time trend of any signal across the entire LWS system, scroll back in time for up to two years and make comparisons against similar trends across various treatment and distribution sites.  This operational insight is further enhanced by providing managers and process engineers with a whole range of analysis capability via a web enabled ad-hod querying interface.
