Reduce water use from urinals
How to deploy innovative technology in your business washrooms to save water and costs.
Urinals can be a major source of wasted water as they typically flush even when they are not being used. An uncontrolled flush can waste around 200-300 cubic metres of water per year, depending on flush frequency and cistern size.
There are a number of technologies that your business could consider to reduce the water that is wasted from flushing urinals.
Efficient urinal technologies
You can use a hydraulic valve to control the frequency of urinal flushing. This system operates on the water inlet pipework. The valve detects when water is being used elsewhere in the washroom, triggering the valve to open and flush the urinals. When no other water is being used the valve stays closed.
Passive infrared sensors detect when someone enters the washroom. The sensor controls a solenoid valve that allows a pre-set amount of water into the cistern. When the cistern is full, it will flush the urinal.
If the working hours at your premises are highly predictable, you can control the urinal flush with a manual quarter-turn ball valve. At the end of the working day this valve can be turned to stop flushing taking place.
You can add a timer to the flush valve. This technology is more reliable than manual turn-off as it does not rely on someone remembering to shut off the cistern valve at the end of each working day.
You can adjust the amount of water that a urinal uses with a number of different devices. A cistern volume adjuster is available in a variety of designs, including a device that works by retaining a proportion of the cistern water behind a dam.
Waterless urinals
There are currently two types of waterless urinals available:
- Siphonic traps contain a barrier that is inserted into the urinal bowl that the urine passes through to the drain. These types of waterless urinals require specialist cleaning and the replacement of the barrier fluid every one to two weeks depending on use.
- Deodorising pads are devices that use a pad impregnated with a deodorising chemical inserted into the S bend. Depending on use, the pad may require replacing once a week.

Reduce water use from toilets
How to reduce water use from toilet facilities in your business premises by looking at efficient washroom technology.
Flushing toilets can be a major cause of water wastage within your business. An office fitted with nine-litre toilet cisterns that serve 100 staff could save hundreds of pounds a year on water and sewerage costs.
There are a number of technologies that your business could consider to reduce the water used by toilets.
Efficient toilet technologies
Siphon mechanisms are fast, easy to fit and can deliver very low flush levels of around 4.5 litres. However, they do cause the cistern to refill slowly, so you should make sure they meet the needs of your business.
As the cheapest option, many businesses opt for a drop valve mechanism to control the cistern flow in their toilets. These systems are ideal for high frequency use, but they do suffer from leakage and may require regular maintenance to remove scale deposits.
The toilet flush can be controlled accurately by using a siphon mechanism with an air valve fitted to the siphon. As a very low cost option, variable flush technology can offer major water savings, as flushes can be as low as four litres of water. However, the technology is not very robust and overall savings can be highly variable.
Dual flushing gives the user a choice of two flush volumes.
Adjusting the position of the ball float can control the water level in the cistern. This could save one litre of water per flush. Your business will, however, have to regularly check that the ball float is in the correct position.
Cistern volume adjusters use a bag - often referred to as a 'Hippo' or 'save-a-flush' bag - that fits into the cistern of the toilet. These bags are also sometimes referred to as cistern displacement devices.
A cistern dam partitions the cistern with a flexible synthetic material to reduce the overall water use with each flush. This technology is cheap and easy to fit.
You could potentially save up to half a litre of water per flush with a delayed action inlet valve. The system can be retrofitted to the cisterns of most toilets. Your business would need to make regular checks to ensure the delay period is correct.

Reduce water use from taps
How you can minimise water usage from taps in washrooms and kitchen areas within your business premises.
Taps can potentially be a huge source of wasted water. There are a number of technologies that your business could consider to reduce water use from taps.
Efficient tap technologies
An isolating ball valve enables you to control the flow of water through the valve. The valve is easy and cheap to fit but may block as scale builds up.
Similar in design and function to an isolating ball valve, the same water savings can potentially be made by fitting a flow restrictor. However, these are also prone to blocking with scale build up.
With a spray tap the nozzle is replaced with a nose that dispenses water as a mist or spray. These systems can be highly effective at saving water, but they can block and cause splashing. They can also be a potential source of legionella if the tap is used infrequently.
With a tap aerator the design of the tap nozzle allows air to mix with water when it exits the tap, giving the appearance of an increase in water flow. These devices are easy to retrofit to existing taps and can deliver similar savings as other techniques.
Using a push tap can control the flow of water to the user. After the user has released the tap, the water flow will stop after a delay of between one and 20 seconds. These devices have a relatively long payback period of between two and three years.
With an electronic tap an infrared sensor under the tap activates the flow of water. The temperature of the water is preset. As the hand of the user does not touch the tap, hygiene can be a major advantage of this technology.
An 'eco-tap' or 'eco-brake' cartridge stops a user from using the full flow that the tap can provide by stopping the tap lever from moving more than halfway. It offers substantial savings as the potential water flow is halved.
A thermostatic mixer valve within the tap can detect the water pressure or temperature and expand the element within the tap. This alters the proportion of hot and cold water that is mixed within the tap.

Reduce water use from showers
How your business can reduce the amount of water used and wasted from showers on your commercial premises.
It is a common misconception that showers use less water than a bath. Modern power showers can use just as much, if not more than, a bath. There are several technologies that your business can use to reduce the amount of water that showers use.
Efficient shower technologies
An isolating ball valve enables you to control the flow of water through the valve. This adjustment could save up to six litres of water per minute. The valve is easy and cheap to fit. However, it does not regulate water pressure and may block as scale builds up.
A shower aerator is fitted between the shower hose and showerhead. The aerator allows air to mix with the water as it leaves the showerhead. This gives the impression of higher water pressure and flow. Water savings can be as high as six litres per minute.
Operating in the same way as a general shower aerator, an aerating showerhead fits into the showerhead itself. It mixes air with the water as it exits the showerhead to give the impression of higher water flow rates. Water savings are around six litres per minute. This technology is not normally suitable for electrically heated showers.
A thermostatic mixer valve within the shower detects the water pressure or temperature and expands the element within the showerhead. This alters the proportion of hot and cold water that is mixed within the shower. Long paybacks can be an issue with this technology, as it cannot be retrofitted to an existing shower.
Operating like push button light switches, the push button shower delivers its water over a set time period. Water savings vary as the button can be pushed multiple times without any cut-off. Maintenance is also required as the pinhole in the diaphragm that operates the push button can become blocked with scale.

Reduce water use from laundry facilities
Minimising water use from laundry facilities by more efficient processes, better detergents and investing in technology.
Laundries in commercial premises are significant users of water and producers of wastewater. Reducing your business' consumption of water in its laundry process will reduce fresh water and wastewater bills.
Before you make any changes to how your laundry facility uses water, it is a good idea to perform a water audit and create a benchmark of your water use that you can measure against - see how to monitor your water use.
Re-washing and programme selection
One of the main reasons that your business could be wasting water in its laundry facility is because washing is continuing longer than necessary. Your business should aim for a rate of three to five per cent of items that need rewashing. A rate of less than three per cent indicates you are over-washing. A rate of more than five per cent indicates inadequate washing.
It is important that you use the correct washing programme to ensure no excessive water or detergent is being used. When you are choosing a programme, you should consider the:
- soiling level of the load and its overall weight
- appropriate level of detergent that should be used
- programme time that each load runs for
Efficient use of detergent and softeners
It is important that you use the correct detergent for each load and it is not used excessively. Using too much detergent increases costs and can require each load to be rinsed for longer. Consider:
- automating detergent doses, as this can be more accurate
- using low-temperature detergents, as they reduce energy costs, may rinse more easily, reduce the risk of colour run and retain better colour brightness
- checking that auto dosing pumps are delivering the correct volume
- setting chemical dosing pumps for low, medium and high dip washes
Using a softener with each washing load can deliver a number of key advantages that include:
- reduced levels of detergent use, which then requires less water to rinse
- reduced scale build-up, which prolongs the life of machinery and reduces the likelihood of leaks
As water softeners require regular regeneration of ion exchange columns, make sure you:
- check the salt levels on a daily basis
- avoid manual or timed regeneration as this can be wasteful
- replace the ion exchange resin when necessary

Reduce water use from catering facilities
Tips on how to reduce water use from the catering facilities in your business to save money and lessen waste.
Caterers and businesses that have a catering facility can take major steps to reduce their overall water use.
How you operate your catering facilities can have a significant impact on water use. For example, good forward planning can mean that frozen food is defrosted naturally, rather than rapidly using water.
Water use reduction tips
Excessive water use can often be the result of habit. One such habit is to leave a tap running when cleaning and rinsing. There are a number of steps your business can take to reduce this water use including:
- increasing the awareness of the catering manager or contractor and staff to the amount of water they are using
- fitting spray heads and flow restrictors to reduce the maximum flow
- installing automatic shut-off taps
- using trigger-operated spray guns
See how to reduce water use from taps.
Of all the appliances your business may use in its catering facility, dish and glasswashers can be the most wasteful. To minimise water use from these appliances, you should:
- only use washers when they are fully loaded
- optimise the cycle times of your machines by consulting the instructions
- consider more water efficient machinery when you need to replace old equipment
Keeping catering equipment up to date and in good working order can have a positive knock-on effect on water efficiency. To make water savings you could:
- link a solenoid-operated valve to a machine - this will ensure water is only used when the machine is in use
- review your steamer operations
- alter the flow of water over authentic wok and noodle cookers
- check the overflow on ice machines
- reduce the flow rate of water to automatic potato peelers
Food waste disposal channels
In some catering facilities, waste food is scraped into a channel with constantly flowing water. You could make water savings by considering:
- turning the water on and off manually or via an infrared sensor
- not using multiple disposal channels
- evaluating alternative ways of disposing of food such as bins or a mesh basket over a sink

Reduce water use from grounds maintenance
How your business can reduce wasted water from maintaining the grounds and gardens of your commercial premises.
Maintaining gardens and grounds typically uses high quantities of water. If your business has a garden or any areas of grounds to manage, there are practical steps you can take to minimise your water use.
Water conservation tips
Your business can significantly cut its water use by following some simple steps:
- Systems such as spray irrigation cause high levels of evaporation. Set your irrigation system to operate first thing in the morning before the air temperature has risen.
- Choose sprinkler systems that operate low to the ground and replace any that shoot their water into the air. This reduces losses from evaporation and wind drift.
- Check the weather forecast. If it is likely to rain the next day, switch off any automatic sprinkler or irrigation systems. If the rain fails to arrive you can simply switch your systems back on.
- When watering has to take place, always use a hose that has an automatic shut-off valve. Trigger-operated hosepipes are ideal as they are cheap to buy and have a very short payback period of about two days.
- Always check that the soil you are about to water actually requires it. Consider installing a soil moisture sensor.
- When you are replacing plants and flowers, look for varieties that are hardy and require less watering. Planting more native shrubs and covering exposed soil with mulch (in late winter) will retain moisture.
- Ensure the soil is properly cultivated to improve the structure and water-retaining properties of the soil
- Keep lawns longer during dry spells. Constant cutting increases the lawn's demands for water.
Alternative water sources
Collecting rainwater is one of the most cost-effective ways of saving water. Installing a water butt or tank that collects rainwater from the roof or drainpipes is a fast and cheap way of reducing your water bill.
If the rainwater you have collected is not sufficient for your needs consider using grey water, for example from washing machines, before turning to fresh water from the mains supply - see water reviews, policies and action plans.

Reduce water use from garages and vehicle cleaning facilities
How your business can reduce water use from the garages and vehicle cleaning facilities on your commercial premises.
A garage or vehicle cleaning facility can use large amounts of water. It is important that you look closely at how your business can save water and use it more efficiently in these areas.
Water saving tips
You should avoid using mains water supplies where possible. Using grey water from other areas of your business, such as catering or laundry facilities, can have a significant impact on your business' overall water use and wastewater bills.
You could also:
- collect your own water supplies via rainwater collection systems to supplement the mains water you use
- use high-pressure water and steam cleaners as they offer more efficient use of mains water for cleaning purposes
- use trigger-operated hoses as they prevent water from being wasted when a hose is left on
Make sure garages have an oil separator installed on surface water drainage systems to prevent pollution. Note that you must clean and inspect your oil separators regularly to ensure they are operating at maximum efficiency.
Wastewater that your garage or vehicle facility produces must be handled correctly. Water can become contaminated with waxes, detergent, particulates and hydrocarbons. Where possible use biodegradable, phosphate-free detergents. Carry out cleaning in an impermeable area where the cleaning water is prevented from running off. This water must always be discharged to the foul drain and not to the surface drain.
Your business should also, where possible, recycle water by removing contaminants. This can be carried out using one or more processes, including:
- filtration
- wax removal
- sedimentation
- centrifugal separation
- reverse osmosis

Wastewater that your garage or vehicle facility produces must be handled correctly. Water can become contaminated with waxes, detergent, particulates and hydrocarbons. Where possible use biodegradable, phosphate-free detergents. Carry out cleaning in an impermeable area where the cleaning water is prevented from running off. This water must always be discharged to the foul drain and not to the surface drain.
Your business should also, where possible, recycle water by removing contaminants. This can be carried out using one or more processes, including:
- filtration
- wax removal
- sedimentation
- centrifugal separation
- reverse osmosis

Reduce water use by product recovery
How to use product recovery techniques to save water at industrial plants and what the benefits of product recovery are.
Any business that uses pipework to transfer products can use product recovery techniques to reduce overall costs and make significant water savings. In many cases, no cleaning is required after product recovery systems have been installed.
A product recovery system uses a piece of technology called a 'pig'. This is a plug or ball that is used inside the pipe and is pushed along under its own power, or via a propellant such as compressed air, nitrogen or water.
The use of a pig to recover materials from your pipework has a number of key benefits:
- valuable raw materials or products are recovered for reuse
- water and other chemicals that are used to clean the pipework can be significantly reduced
- any additional water that is used to clean the pipework will have lower effluent loads and save you money on disposal costs
- reductions in cleaning time that can cut the production downtime of a process

Reduce water use by cleaning-in-place
How cleaning-in-place techniques can benefit your business by reducing water use and improving efficiency.
The idea of cleaning-in-place (CIP) techniques is to remove 'soil' from your process equipment. This means that your business can clean its machinery with little or no disassembly.
Using CIP within your business can deliver a number of advantages over manual cleaning. These include:
- higher levels of machinery cleanliness
- reduced levels of chemical and water use
- recovery of fluids that can be reused
- increased levels of automation that can lead to overall efficiency savings
The CIP systems that your business puts in place need to be evaluated and possibly modified over time to give the highest levels of water and cost savings. You can optimise your CIP system in a number of ways. These include:
- checking the overall efficiency of your CIP programme to include flow rates and cycle times, cycle volumes, sequencing and temperature
- optimising pre-rinse
- optimising the detergent wash
- optimising post-rinse
- disinfectant use
- final rinse
- changes to the equipment in use

Reduce water use with cleaning and rinsing techniques
Different cleaning and rinsing techniques you should consider to reduce water use at your industrial premises.
Your business can take practical steps to reduce its water use by adopting a range of cleaning and rinsing technologies and techniques.
Many businesses don't clearly understand what constitutes dirty or used water. In many cases, this water can be reused effectively in other areas of your business. Completing an audit of what you consider to be 'used' water and then evaluating how this could be reused will often reveal significant areas for water conservation and cost savings.
You could cut your business' water use significantly by adopting cleaning-in-place (CIP) techniques. For more information about CIP, see how to reduce water use by cleaning-in-place.
Using scrapers, squeegees, brushes or hoses to clean an area can reduce the cleaning time and thus save water. They can also help you to eradicate bacterial growth and provide your business with a more hygienic environment.
If solids are likely to be washed easily into drains, fitting drain covers can have a major impact on the effluent that your business produces. This will save you money by reducing the effluent charges your business has to pay.
After water has been used, it is often possible to recycle the water after it has been suitably treated and then use it again. Treatment technologies you could use include:
- filtration
- clarification/sedimentation
- centrifugation
- flotation
- ion exchange
- distillation/stripping
- absorption/adsorption
Using counter-current rinsing can save your business large amounts of water. This system moves your business' products through a series of tanks or rinsing stages. A product is first rinsed using dirty water and then progressively cleaner water as it moves from tank to tank.

Reduce water use by monitoring and adjusting the water flow
How water flow monitoring technologies and techniques can help with industrial facility water use reduction.
There are a number of technologies and techniques that you could consider to adjust water flow and reduce water use.
Sprays and jets can have a dramatic impact on how water is used in your business. Having the ability to better direct the water jet can mean you use water more efficiently. New technology allows you to use much lower pressures, which saves water overall.
You can fit turbidity probes to pipework to monitor the flow of product. Turbidity probes can sense the concentration and speed of product flow through a pipe. The technology can control valves that direct the flow. In addition, the system can reuse product that has been recovered.
Using similar technology to a turbidity probe, a conductive probe can measure levels of acidity and alkalinity in a water system. This information gives the system operator the ability to improve the level of cleaning-in-place that the system is using.
If your systems do not require a constant stream of water, you can use a shut-off system to regulate the flow. This saves money and water, as in many continuous flow systems the excess water simply flows into a drain.

Reduce water by re-evaluating your processes
How to re-evaluate your production processes to find out where you can make water savings and cost savings.
Reviewing the production processes that you use within your business can reveal potential areas where you can save water. The savings that your business could make include:
- reduced water cost
- reduced effluent charges
- eliminating the need to treat effluent before discharge
- reduced disposal of wastes and sludges
- product recovery
Your business should evaluate its water use in the context of the processes it uses in its day-to-day operation. Often a small change to a process can deliver significant water savings and a reduction in cost as well - see process efficiency to cut waste.

Reduce water use from your process plant
How to implement water use reduction measures from process plant such as industrial cooling and heating systems.
The machinery and plant in your business can be a major contributing factor to your water use. Looking closely at the plant you use and how water is used within them will highlight which you could modify to make them more water efficient.
Liquid ring vacuum pumps use a continuous supply of water, typically heated to 15 degrees Celsius, to provide a seal. You can make significant water savings by reusing wastewater for this process, and by cooling the seal water.
Typically, businesses that have equipment that needs to be cooled will connect their equipment to the main water supply and use this as a 'once through' process, discharging the used water into a drain. You can make substantial water savings by reusing water to provide the cooling.
You can use refrigeration units, air blast chillers and evaporation towers to cool the water. Also, if there is significant heat build-up as the water is used, you can recover this heat with a heat exchanger.
Cooling towers generally need to use make-up water to replace blowdown or evaporation. The amount of make-up water needed depends on the cooling load required. Minimising the cooling load will reduce the use of fresh water as make-up water.
The cooling towers your business may use also lose water as mist or spray. You can install optimised automatic blowdown control, which will use this spray loss to clean your cooling tower of solid deposits, saving water overall.
You may be able to make significant water and cost savings by using heating and cooling systems efficiently, see water reviews, policies and action plans.

Sprays and jets can have a dramatic impact on how water is used in your business. Having the ability to better direct the water jet can mean you use water more efficiently. New technology allows you to use much lower pressures, which saves water overall.
You can fit turbidity probes to pipework to monitor the flow of product. Turbidity probes can sense the concentration and speed of product flow through a pipe. The technology can control valves that direct the flow. In addition, the system can reuse product that has been recovered.
Using similar technology to a turbidity probe, a conductive probe can measure levels of acidity and alkalinity in a water system. This information gives the system operator the ability to improve the level of cleaning-in-place that the system is using.
If your systems do not require a constant stream of water, you can use a shut-off system to regulate the flow. This saves money and water, as in many continuous flow systems the excess water simply flows into a drain.

Reduce water by re-evaluating your processes
How to re-evaluate your production processes to find out where you can make water savings and cost savings.
Reviewing the production processes that you use within your business can reveal potential areas where you can save water. The savings that your business could make include:
- reduced water cost
- reduced effluent charges
- eliminating the need to treat effluent before discharge
- reduced disposal of wastes and sludges
- product recovery
Your business should evaluate its water use in the context of the processes it uses in its day-to-day operation. Often a small change to a process can deliver significant water savings and a reduction in cost as well - see process efficiency to cut waste.

Reduce water use from your process plant
How to implement water use reduction measures from process plant such as industrial cooling and heating systems.
The machinery and plant in your business can be a major contributing factor to your water use. Looking closely at the plant you use and how water is used within them will highlight which you could modify to make them more water efficient.
Liquid ring vacuum pumps use a continuous supply of water, typically heated to 15 degrees Celsius, to provide a seal. You can make significant water savings by reusing wastewater for this process, and by cooling the seal water.
Typically, businesses that have equipment that needs to be cooled will connect their equipment to the main water supply and use this as a 'once through' process, discharging the used water into a drain. You can make substantial water savings by reusing water to provide the cooling.
You can use refrigeration units, air blast chillers and evaporation towers to cool the water. Also, if there is significant heat build-up as the water is used, you can recover this heat with a heat exchanger.
Cooling towers generally need to use make-up water to replace blowdown or evaporation. The amount of make-up water needed depends on the cooling load required. Minimising the cooling load will reduce the use of fresh water as make-up water.
The cooling towers your business may use also lose water as mist or spray. You can install optimised automatic blowdown control, which will use this spray loss to clean your cooling tower of solid deposits, saving water overall.
You may be able to make significant water and cost savings by using heating and cooling systems efficiently, see water reviews, policies and action plans.

How to save water at industrial premises
A series of different options for your business to implement water saving measures at your industrial premises.
Your business can save water in a number of key ways at industrial sites:
- recovering materials using a product recovery system
- cleaning equipment using cleaning-in-place systems
- using other cleaning and rinsing techniques
- using technology to monitor and adjust the rate of water flow
- reconsidering your processes
- reducing water from the process plant that you use
You should also focus on:
- adopting a systematic approach to reduce your water use in the most effective way
- using heating and cooling systems efficiently
- controlling water pressure
- avoiding leaks and overflows
- checking water meters and water bills
- reducing your mains water use by collecting rainwater and reusing water
For more information, see water reviews, policies and action plans.
If you have an environmental management system, or are intending to set one up, you should use this to manage your water use.
If your business also has facilities such as washrooms, catering or laundry areas, see how to save water at commercial premises.

Reduce water use by product recovery
How to use product recovery techniques to save water at industrial plants and what the benefits of product recovery are.
Any business that uses pipework to transfer products can use product recovery techniques to reduce overall costs and make significant water savings. In many cases, no cleaning is required after product recovery systems have been installed.
A product recovery system uses a piece of technology called a 'pig'. This is a plug or ball that is used inside the pipe and is pushed along under its own power, or via a propellant such as compressed air, nitrogen or water.
The use of a pig to recover materials from your pipework has a number of key benefits:
- valuable raw materials or products are recovered for reuse
- water and other chemicals that are used to clean the pipework can be significantly reduced
- any additional water that is used to clean the pipework will have lower effluent loads and save you money on disposal costs
- reductions in cleaning time that can cut the production downtime of a process

Reduce water use by cleaning-in-place
How cleaning-in-place techniques can benefit your business by reducing water use and improving efficiency.
The idea of cleaning-in-place (CIP) techniques is to remove 'soil' from your process equipment. This means that your business can clean its machinery with little or no disassembly.
Using CIP within your business can deliver a number of advantages over manual cleaning. These include:
- higher levels of machinery cleanliness
- reduced levels of chemical and water use
- recovery of fluids that can be reused
- increased levels of automation that can lead to overall efficiency savings
The CIP systems that your business puts in place need to be evaluated and possibly modified over time to give the highest levels of water and cost savings. You can optimise your CIP system in a number of ways. These include:
- checking the overall efficiency of your CIP programme to include flow rates and cycle times, cycle volumes, sequencing and temperature
- optimising pre-rinse
- optimising the detergent wash
- optimising post-rinse
- disinfectant use
- final rinse
- changes to the equipment in use

Reduce water use with cleaning and rinsing techniques
Different cleaning and rinsing techniques you should consider to reduce water use at your industrial premises.
Your business can take practical steps to reduce its water use by adopting a range of cleaning and rinsing technologies and techniques.
Many businesses don't clearly understand what constitutes dirty or used water. In many cases, this water can be reused effectively in other areas of your business. Completing an audit of what you consider to be 'used' water and then evaluating how this could be reused will often reveal significant areas for water conservation and cost savings.
You could cut your business' water use significantly by adopting cleaning-in-place (CIP) techniques. For more information about CIP, see how to reduce water use by cleaning-in-place.
Using scrapers, squeegees, brushes or hoses to clean an area can reduce the cleaning time and thus save water. They can also help you to eradicate bacterial growth and provide your business with a more hygienic environment.
If solids are likely to be washed easily into drains, fitting drain covers can have a major impact on the effluent that your business produces. This will save you money by reducing the effluent charges your business has to pay.
After water has been used, it is often possible to recycle the water after it has been suitably treated and then use it again. Treatment technologies you could use include:
- filtration
- clarification/sedimentation
- centrifugation
- flotation
- ion exchange
- distillation/stripping
- absorption/adsorption
Using counter-current rinsing can save your business large amounts of water. This system moves your business' products through a series of tanks or rinsing stages. A product is first rinsed using dirty water and then progressively cleaner water as it moves from tank to tank.
