Improve planning, inform cost-effective investment decisions and mitigate risks to ensure consistent, robust water supply now and into the future.

The Hydro-Logic® Aquator software platform provides modellers, water resource planners and hydrologists with reliable, actionable insight into complex water resources systems, enabling them to assess critical supply, demand and environmental factors and analyse a range of scenarios. 

Designed to inform, support and deliver robust water supply plans in the heavily regulated UK public water sector, it has proven itself in the most demanding of markets—and with a wide range of customisation features, capabilities and support options it can flex to meet the challenges of even the most demanding strategic or operational water management planning project. 

Hydro-Logic® Aquator has been developed by, for and with water resource professionals to ensure that every output may be optimised to match supply with demand, whatever the population or climate pressures.

Hydro-Logic® Aquator is a modelling software platform that enables modellers, hydrologists, engineers and analysts to create and run complex models of real-world water resource supply networks and systems, giving water utilities, regulators and consultants the critical insight they need in order to make better water management decisions. 

The software incorporates a full component toolbox that enables the modelling of all components typically present in a water resource system. Complex operating rules can be developed that accurately reflect real-world operational constraints such as reservoir control curves, abstraction licence conditions, minimum flow requirements and leakage.

As part of the Hydro-Logic® solution set, Hydro-Logic® Aquator has been developed by, for and with expert water industry professionals to ensure that every output may be optimised to match supply with demand, whatever the population or climate pressures.

Hydro-Logic® Aquator is also the only water resource supply software in the world approved to use Microsoft Visual Basic® for Applications (VBA) to customise its models—making it uniquely capable of helping people to address their most important water management challenges.

Applications

  • Conjunctive/mixed use water resource systems
  • Public water supply
  • River catchments, lake and reservoirs
  • Navigation and canal systems
  • Hydropower
  • Irrigation resource management

Plan and manage water supply and demand

Hydro-Logic® Aquator enables water providers to determine whether or not existing or planned water networks are able to supply sufficient water to meet customer demand—and to take action accordingly to ensure uninterrupted supply to residential, commercial and industrial customers now and into the future. 

Models help users to identify, assess and mitigate supply risks such as population changes and climate disruptions, helping utilities to deliver robust strategic and operational water resource plans that improve their costs of operation, investment and resource deployment. 

Audit suppliers and develop policy

Environmental and legislative agencies need to understand the supply and demand models used by water providers, and they need to factor in future supply and demand in order to develop meaningful water abstraction policies. Hydro-Logic® Aquator provides this critical insight. 

Develop the right models for your system

From simple models with a few components to large, complex stochastic models with over a thousand elements, Hydro-Logic® Aquator provides the modelling flexibility that water suppliers and environment agencies need to understand the water environment. 

Improve hydropower profitability

Hydro-Logic® Aquator provides hydropower businesses with reliable, actionable insight into complex water resources systems, enabling them to assess develop optimal operating policies for turbine use (based on reservoir storage and energy prices) whilst meeting environmental factors or other constraints.

The platform allows simulation and analysis across a range of scenarios in order to generate in the most cost-effective way over the short, medium and long term. Scenarios of asset change or outage can be assessed for their impacts and/or benefits.

Answer critical questions

Hydro-Logic® Aquator can help users to address issues such as:

  • Future climate change risks
  • Asset management decision making
  • Strategic scenario planning (e.g. water trading or transfers)
  • Alternative option/solution testing
  • System yield or availability estimation
  • Extreme weather and system resilience testing
  • Outage reviews and operational efficiency
  • Reservoir or operational control curve optimisation

The Hydro International consulting team offers modification options and will be happy to develop custom models to meet these kinds of applications as well as any others that you might require.

If you require assistance from Hydro-Logic® Services in this area please contact us.

Users construct a representation of a water system by dragging and dropping components from a toolbox onto the schematic area. Users then enter values for the parameters required by each component in order to generate a fully working model.

Each component encapsulates a set of operating rules; Hydro-Logic® Aquator seeks to satisfy daily demand by automatically enforcing these rules no matter how complex the system.

While obeying these rules Aquator executes a linear optimisation algorithm known as Aqua solver, which tries to find the best solution for daily water movement by supplying at lowest cost when water is plentiful or supplying according to the state of resources when water is scarce.

Custom rules and modifications

If custom rules specific to an organisation are required, or complex interrelationships exist between components, users can use Microsoft® Visual Basic® for Applications (VBA) to modify the built-in rules.

While users might be comfortable using VBA themselves, the Hydro-Logic® Services team offers modification options and will be happy to develop custom models.

If you require assistance in this area please contact us.

The Aquator Suite

Hydro-Logic® Aquator XV

XV is the latest Hydro-Logic® Aquator core simulation package, and is a complete re-write of the modelling platform using the latest Microsoft development tools. It implements the same optimisation algorithm (Aqua-Solver2) that was provided in the previous release of 4.3.

Hydro-Logic® Aquator XM

XM (eXecution Manager) is a control program add-on for undertaking different types of analysis based on Hydro-Logic® Aquator water resource system models.

XM can execute multiple instances of Hydro-Logic® Aquator simultaneously to complete the analysis in a shorter time than would be possible using a single instance of the software.

Q

Will I get the same results from Hydro-Logic® Aquator versions 4.3 and XV?

A

It's unlikely that you will get identical results for a model of significant complexity. The reasons for this are that (i) the algorithm has been re-written and re-ordered to increase speed; (ii) we observe in many models that more than one solution is optimal, i.e. there isn’t one unique solution, so XV may choose a different solution from 4.3 due to (i); and (iii) rounding errors will differ (XV does all calculations in double precision whereas V4.3 used single precision). However, the important point is that closely similar solutions should be achievable because fundamentally the same algorithm has been implemented.

Q

I'm using Hydro-Logic® Aquator 4.3 - do I need to switch to XV?

A

It's not necessary to switch from 4.3 to XV, but we would recommend it. We are no longer developing 4.3 - all future development work will be on XV. If you wish to switch then the Hydro International consulting team can help you to move your models across from 4.3 to XV.  

Q

Can Hydro-Logic® Aquator by modified?

A

Yes. If custom rules are required, or complex interrelationships exist between components, users can use Microsoft® VBA to modify the built-in rules. The Hydro International consulting team also offers modification options and will be happy to develop custom models.

Q

What hardware do I need to run Hydro-Logic® Aquator?

A

Windows 8 or Windows 10, 32 or 64 bit; Recommended screen resolution: 1600 x 900 (HD+) or better; Recommended processors: Intel Core i5 (or equivalent) or better for large models; Recommended RAM: 4GB or greater
