Criticality Analysis with WaterGEMS
Criticality Analysis, included in WaterCAD and WaterGEMS, lets engineers identify those areas to be shut down to repair leaks and those areas that will be impacted if they don't.

Pressure Management with WaterGEMS
Sometimes there are leaks that can’t be found (unavoidable leakage) or can't be fixed in the near future. In those cases, water professionals can use WaterCAD and WaterGEMS’ Pressure Dependent Demands (PDD) analysis to study the amount that they can expect to reduce leakage by reducing pressure and to look at the impact on customer service.

Pipe Breakage Control with HAMMER
HAMMER can help engineers reduce pipe breakages caused by high pressure transients (or water hammer), identify the areas where breakage is likely to occur, and design surge protection devices.
Recorded eSeminar: Reduce Transient to Limit Breakage (by Angela Battisti, Bentley)
Recorded eSeminar: Active Leakage (by Manmohan Prajapat, Bentley)
Water Leakage Strategy: Find - Repair - Reduce - Prevent
This presentation focuses on how water modeling software can help you reduce water loss and answer the following questions:
- Where are the leaks?
- Who will be left out of service during repairs?
- Can we reduce the pressure to minimize leaks?
- How can we protect our system?
