The Operations Simulator's solver runs from the offline database and during startup can extract real-time data from the online Aquadapt database for a current snapshot of a client's distribution system, or use data from any selected time period in the Aquadapt system's archive.

A separate operator's user interface allows users to change normal operational parameters as well as some level and flow constraints, which usually require supervisory level access on the live system. Operators can test scenarios such as equipment failure or maintenance schedules, enabling them to see what effect it will have on their system including real-time calculation of cost. They can then investigate effective solutions before applying them to the live environment.

Management staff, engineers and planners can also modify physical characteristics of the distribution system, such as pump curves, storage tank dimensions and electrical tariffs. They can then run the solver to evaluate the operational and cost impact of these proposed changes. In a changing electricity market this will help management to determine which tariff structure is the most cost effective for their individual system.

Operations Simulator in synchronized mode users can select the option of receiving regularly updated data from the live system. Operators have the ability to continually work with the most up-to-date information. As a stand-alone application, operators can confidently manipulate settings and run scenarios without affecting the live Aquadapt system.

One of the strengths of Aquadapt software is its ability to predict levels and flows 48 hours in advance. It can preemptively identify problems, such as minimum storage, where proactive steps by the operator can lessen the consequences. Having identified the issue the operator can use the Operations Simulator to develop effective counter strategies, often before the problem occurs.

Operations Simulator can also be used as a training tool. As it is a complete reproduction of the Operator Panel it looks and feels like the live system and provides a realistic environment to safely train operators. Training can incorporate everything the live system can do including:

• Changing pump schedules - by zone or the entire system;
• Setting water treatment plant rates;
• Setting flow and pressure set points;
• Response to alarms and warnings;
• Operation in different seasons.

Operators can also be trained to deal with more infrequent situations such as extreme weather events or plant outages. The engineer's user interface allows a greater range of changes to be made including the addition of new physical equipment into the distribution system. The information produced by the Operations Simulator can be used with confidence for project cost/benefit justification and can be exported for further analysis if required. Most changes can be made using a graphical interface, like the pump curve screen shown left, or through direct SQL access to the simulator database.
