In food production, water and energy are rarely separate issues. Every liter of water that enters a plant may need to be pumped, filtered, heated, pressurized, sprayed, collected and treated. Every cleaning cycle also affects labor planning, production availability, wastewater volume and hygiene verification.
That is why water energy performance matters. It is not only a sustainability metric. For plant managers, hygiene teams and operations directors, it is a practical indicator of how effectively a facility converts resources into clean, controlled and productive processing conditions.
In poultry processing and other food production environments, the challenge is clear: hygiene standards must remain strict, while costs, water pressure, labor availability and environmental expectations continue to increase. Improving water and energy performance helps bring those priorities together.
What water energy performance means in a food plant
Water energy performance describes how efficiently a production facility uses water and energy to achieve the required cleaning, hygiene and processing outcomes. It is not the same as simply using less water. A plant can reduce water use in the wrong place and create higher hygiene risk, longer cleaning time or more rework.
A useful performance view connects four questions:
- How much water is used per cleaning task, production hour, line section or kilogram of product?
- How much energy is required to pump, heat, pressurize or treat that water?
- What cleaning result is achieved on belts, crates, shackles, filters and equipment surfaces?
- How much labor, downtime and wastewater are created in the process?
This combined view is important because water savings can influence energy use, and energy savings can influence cleaning quality. For example, reducing flow without improving cleaning impact may increase manual work. Using very high volumes of hot water may deliver visible cleaning, but it can increase heating costs, wastewater load and humidity in the production environment.
The goal is not the lowest possible water use. The goal is the right amount of water, delivered with the right impact, at the right point in the process, with a reliable hygiene outcome.
Why water and energy should be managed together
In many plants, water and energy are managed by different teams or budgets. Water may sit under utilities or sustainability, while energy is tracked by engineering or finance. Cleaning performance may be owned by hygiene, sanitation or production. This separation can hide the real cost of cleaning.
A cleaning system that uses excessive water also creates energy demand. Water may need to be heated, pumped through pipework, pressurized through nozzles and managed as wastewater. The more water that is used unnecessarily, the more supporting infrastructure is required.
The ISO 50001 energy management standard encourages organizations to take a structured approach to energy performance. In food production, that structure becomes even stronger when water-related energy loads are included in the analysis.
| Resource factor | Typical operational impact in food production |
|---|---|
| Water volume | Affects utility cost, wastewater volume, floor conditions and sustainability reporting |
| Water temperature | Influences heating demand and total energy cost |
| Pumping and pressure | Determines electrical load and cleaning force at the point of use |
| Spray control | Affects overspray, cross-contamination risk, water waste and operator safety |
| Cleaning duration | Influences labor hours, downtime and production availability |
| Wastewater load | Affects treatment capacity, discharge cost and environmental pressure |
When these factors are reviewed together, teams can make better decisions. A hygiene manager sees whether cleaning remains consistent. A technical manager sees whether the system is practical to integrate. A plant manager sees whether the improvement supports cost control and production continuity.
Hygiene performance depends on controlled cleaning, not only high consumption
In poultry production, cleaning challenges are often concentrated around high-risk and hard-to-reach areas. Conveyor belts, shackles, crates, filters, guides and transfer points can collect organic material during production. If soil remains in these areas, it can affect product quality and increase contamination risk.
Traditional cleaning often relies on high water volume, manual intervention and repeated passes. This may appear safe because it is familiar, but high consumption does not automatically mean better control. Water that is not directed properly may create splash, overspray and inconsistent coverage. In some situations, excessive spraying can move residues into surrounding areas rather than removing them in a controlled way.
Better water energy performance starts with cleaning impact. The question is whether water reaches the surface with enough mechanical effect to remove soil efficiently, without using unnecessary volume. This is where nozzle selection, spray angle, distance, pressure, droplet behavior and line-specific positioning become important.
For food safety teams, the practical value is consistency. Controlled cleaning points can reduce dependence on individual operator technique. They can also support more repeatable cleaning during critical process steps, especially where inline cleaning is possible.
Where water and energy losses usually occur
Most food plants do not waste water and energy in one obvious place. Losses are usually spread across many small decisions, older systems and habits that have become normal over time.
Common sources of underperformance include open hoses, poorly positioned spray bars, worn nozzles, cleaning systems that run when no product is present, excessive pressure without useful impact, manual cleaning in areas that could be cleaned inline, and equipment designs that require frequent disassembly.
In poultry processing, the issue is often amplified by production speed and soil load. Equipment needs to be cleaned effectively, but available time is limited. If a cleaning process takes too long or requires too much manual work, it can affect production planning and labor allocation.
A practical review should look at both visible and hidden losses. Visible losses include water running to drain, overspray and operators repeating tasks. Hidden losses include heated water demand, pump energy, extra wastewater treatment, line stoppages and inconsistent cleaning that requires follow-up work.
For a more focused approach to water reduction, IWC also covers practical methods in its article on how to reduce water consumption in food processing lines.
Measuring performance before making changes
Before investing in new cleaning technology or changing procedures, plants should build a baseline. This does not need to be complicated, but it should be specific enough to support decisions.
Start by selecting a defined cleaning application, such as a conveyor belt, crate washer area, shackle line or filter cleaning point. Then measure the resources used, the cleaning time and the outcome. The strongest business cases often come from applications where water, energy, labor and hygiene challenges overlap.
| Measurement area | What to track | Why it matters |
|---|---|---|
| Water use | Flow rate, run time and frequency | Shows the real volume used per task or line section |
| Energy use | Pumping, heating and compressed air demand where relevant | Helps calculate total utility impact |
| Labor | Operators required and time spent cleaning | Identifies manual workload and potential savings |
| Downtime | Production interruption or cleaning window length | Links cleaning to capacity and scheduling |
| Cleaning result | Visual checks, ATP testing or site-approved verification methods | Confirms whether performance meets hygiene requirements |
| Wastewater | Drain load and treatment impact | Connects cleaning to downstream cost and capacity |
The baseline should include actual operating conditions, not only design assumptions. Many systems perform differently after years of use, especially when nozzles wear, pipe pressure changes or manual routines drift from the original procedure.
How smarter cleaning improves water energy performance
Smarter industrial cleaning improves performance by applying cleaning force more precisely. Instead of relying mainly on large water volumes, the system should create effective contact between water and the surface that needs to be cleaned.
IWC International’s Undine® technology supports this approach by mixing water and compressed air under pressure to create high-velocity microdroplets. The practical purpose is to improve cleaning impact while reducing unnecessary water use. For applications such as conveyor belt cleaning, crate cleaning, shackle cleaning and other processing equipment, this can help plants move toward a more controlled and efficient cleaning process.
Depending on the application, current situation and production environment, Undine® technology can save up to 70% on water and energy consumption and up to 60% on labor costs. These results are not automatic, and they should always be evaluated against the specific line, soil type, hygiene requirement, operating hours and integration conditions.
A complete assessment should also consider compressed air supply, pump requirements, water temperature, available space, maintenance access and production continuity. The best solution is not always a standard unit. In many food production environments, the right configuration depends on the process step and the specific contamination-control challenge.
This is especially relevant in poultry processing, where multiple line areas may require different cleaning strategies. A shackle line has different access points and soil behavior than a conveyor belt. A crate washing area has different volume and handling demands than a filter cleaning application. Treating each area as a separate performance case leads to better technical decisions.
The business case goes beyond the utility bill
Water and energy savings are important, but they are only part of the value. For many plants, the strongest business case includes labor reduction, less manual intervention, improved cleaning consistency and reduced downtime.
A cleaning process that uses less water but still requires the same number of operators may deliver a smaller operational benefit than expected. A system that reduces manual cleaning time, limits disassembly and improves line availability may create value across multiple departments.
For decision-makers, the business case should include:
- Utility costs for water, heating, pumping and wastewater treatment
- Labor hours required for cleaning, inspection and re-cleaning
- Production time lost during cleaning, disassembly or manual intervention
- Maintenance requirements, spare parts and accessibility
- Hygiene verification results before and after the improvement
- Sustainability targets related to water use, energy use and wastewater reduction
This broader view helps avoid a common mistake: judging a cleaning improvement only by the initial investment. In food production, cleaning technology should be assessed over its operational life. If a solution reduces resource use, supports hygiene consistency and fits the existing production process, it may contribute to both cost control and risk reduction.
Integration matters as much as technology
Even strong cleaning technology can underperform if it is not integrated correctly. Food plants need solutions that work with existing equipment, utilities, hygiene routines and production planning.
Important integration questions include where the cleaning unit will be placed, how it will be accessed for maintenance, whether it can operate inline, how spray is contained, how water is drained, how operators interact with the system and how results will be verified.
Technical teams should also check whether the solution can handle the demands of the production environment. Poultry plants, meat processing facilities and food manufacturing lines are wet, time-sensitive and mechanically demanding. Equipment must be robust, accessible and practical for sanitation and maintenance teams.
This is why process expertise matters. IWC International does not approach industrial cleaning as a generic service. The company focuses on contamination-control technology, inline cleaning and custom solutions for demanding food production environments. That combination is important when a plant needs to improve hygiene and reduce water and energy use without creating new operational problems.

Turning performance into a continuous improvement metric
Water energy performance should not be treated as a one-time project. Once a plant improves a cleaning application, the same method can be used to identify the next opportunity.
A practical continuous improvement process starts with a baseline, a targeted improvement and a verification period. After that, the plant can standardize the new process and monitor the main indicators over time. This helps prevent performance from drifting back due to nozzle wear, changed operating conditions or undocumented manual workarounds.
For multi-site food production companies, the same framework can support benchmarking. Plants may face different water prices, labor availability or energy costs, but the same basic question applies: how much resource is required to achieve the required cleaning outcome?
When water, energy, labor and hygiene data are viewed together, improvement opportunities become easier to prioritize. The result is a cleaner and more efficient production environment, supported by measurable operational data.
FAQ’s about water energy performance in food production:
What does water energy performance mean in food production? It means measuring how effectively a plant uses water and energy to achieve required cleaning, hygiene and processing outcomes. It connects water volume, energy demand, cleaning quality, labor, downtime and wastewater impact.
Why is water energy performance important in poultry processing? Poultry processing has strict hygiene requirements, high production speeds and equipment that can be difficult to clean. Better water and energy performance helps plants improve cleaning control while reducing unnecessary water use, utility demand and manual work.
Can a plant reduce water use without compromising hygiene? Yes, but only when reductions are based on controlled cleaning performance. Simply lowering flow can create problems. The cleaning system must still deliver enough impact, coverage and consistency for the specific equipment and hygiene requirement.
How can a food plant measure cleaning-related water and energy use? A plant can start by measuring flow rate, run time, water temperature, pumping or compressed air demand, labor hours, downtime and hygiene verification results for a specific cleaning application. This creates a baseline for improvement.
How does Undine® technology support water and energy savings? Undine® technology mixes water and compressed air under pressure to create high-velocity microdroplets. Depending on the application and production environment, this can improve cleaning impact while reducing water, energy and labor use. Results should always be assessed case by case.
