Plant Designer

Save days in time for water, industrial, biological and desalination plants design.

Water designer is used by some of the world leaders in their industry.

Used by over 900 Engineers to design 2500+ plants; all in record time.

Skip the manual, repetitive and linear methods of water simulation

Best-practice modelling approaches

Plant Designer enables engineers and consultants to run water simulations using best-practice modelling approaches.

Built for team collaboration

Unique automated optimization capability, collaborative change control and audit trail, speeding up design times significantly.

Intuitive drag-and-drop interface

Easy-to-use drag and drop interface with pre-populated assumptions for common designs. Scenarios up and running quickly.

Automatic calibration & validation

Reduce model calibration time with our water simulation software

EVS Water Plant Designer includes a unique automatic calibration function, where thousands of model configuration scenarios are simultaneously compared and evaluated to provide the most accurate and reliable calibrated model configurations for the target design.

Workflow & collaboration

Automatic production of key engineering deliverables for water simulations

Automatically produce your engineering deliverables for water treatment plant design, including material balances, plant and equipment sizing, stream properties, specification modelling, electrical load schedules, equipment schedules and design reports.

Best-practice models & Design tools

Model operational scenarios and run water simulations to design for your requirements

EVS Water Plant Designer allows you to design to your specific water quality and cost targets, with easy comparison of key lifecycle metrics and performance commitments for each design option.


Here are answers to common questions about Plant Designer. Reach out to our team today if you don't see the answer you are looking for.

EVS Water Plant Designer is a process design and virtual marketplace application for water treatment. You will be able to effectively design a water treatment plant, run all your boundary condition scenarios, generate vendor RFQs and obtain pricing and equipment datasheets, produce a PFD that can be either exported to CAD software, produce a Mass & Heat balance in Excel, produce a process design report in Word, generate a lifecycle evaluation, electrical load schedule, equipment lists and other documentation relevant to process design. The software will size each unit operation or you can choose to specify the dimensioning data.

Every modelling result will provide unit operation sizing data, stream properties, stream concentrations, mass flows, precipitated solids, information about scaling and corrosion and saturation indices. The software predicts solubility in each stream by using a sophisticated speciation engine that has been calibrated and validated for process conditions, also considering the impact of dissolved gases on redox and equilibrium relationships between inorganic species. It will highlight where you might have a process design issue or when you have exceeded a parameter threshold.

You can export the flowsheet, generate a mass & heat balance, chemical consumption tables, process design & modelling reports, operating costs, vendor RFQ's, capital costs, electrical load schedules, equipment lists. There is no vendor lock-in - these documents can be exported either as a .DXF, .XLS, .DOC, .EMF or .PDF depending on the type of deliverable.

Currently, there are over 60 unit operations that are common to water and wastewater treatment. These include from chemical dosing to conventional settling processes such as clarifiers, filters and also membrane systems, thermal systems with electrolytic systems on the way. Unit Operations are split between single feed, dual feed or countercurrent operations like a cooling tower or heat exchanger, mixers, splitters and rotating equipment such as pumps, blowers, compressors. Biological treatment processes are based on the ASM modelling framework and cover the key operations related to aerobic treatment.

You can either speak with our process support by clicking on Contact Support under the Help tab or you can send an email to or if your question relates to a particular plant design or modelling result, you can check the box "Shared with AqMB Support" which will generate a support case and one of our process engineers will be assigned to help you.

Consult the Plant Designer manual for a list of unit operations that are currently simulated or consult with a member of the pre-sales team if unsure.
