Restaurants, what are your water management strategies?

It is a well-known fact that restaurants use large amounts of water. This water is used for cooking delicious food, making drinks, cleaning dishes and floors, and much more. However, in today’s time of serious drought and mismanagement of resources, it is imperative to have sound and sustainable water management strategies in place.

As a restaurant owner and manager, it can be difficult to devise and implement said strategies, which is why it is better to hire companies such as PROXA Water to create and build these systems. There are, however, some water-saving tips you can follow to boost the technical and complex systems devised and created by companies.

What can I do to be more water conscious?

Other than installing a state-of-the-art water processing system from a company, you can follow some simple and effective tips in order to be a more water conscious restaurant.

Install low-flow pre-rinse nozzles

It is common practice in many restaurants to pre-rinse dishes before placing them in the dishwasher. While this is hygienic and a healthy practices, it is also a way to waste valuable water resources. Installing low-flow nozzles means that the taps are only using 2.5 litres per minute of water, rather than the higher amount of 19 litres per minute. These nozzles are easy to install as you simply remove the old one and screw the new one into place.

Fix all leaky taps

Other than being highly annoying, a tap can cause an immense loss of water and is very wasteful. Not only are you passively wasting water, you are also incurring a huge water bill, as water use is not categorised into taps that are on and in use and taps that are simply leaking. If you consider what you could be using this wasted water for, it is easy to see why it is vital to repair or replace leaky or damaged taps.

Go for low-flow aerators

A restaurant kitchen requires a lot of handwashing for health and safety reasons. Installing a low-flow aerator at all handwashing stations – including those in the kitchen and bathroom – will ensure that water comes out in a lower flow, which is an inexpensive and efficient way to save water in your restaurant. Do not reserve this only for staff, but include your public restrooms too.

Assess your water usage areas

You cannot make any decisions on where to cut back on water usage if you are unaware of the areas that utilise it the most. Your checklist should include aspects such as sensors on automatic taps or faucets, toilets and urinals, dishwasher nozzles, pressure gauges, gaskets, automatic solenoid valves and other water usage points. During these regular assessments, you should also repair or replace any items that need it. Ensure that your staff is also highly water-wise in everything they do, as they are the ones who are using taps and water usage points.

Use air-cooled ice machines

A water-cooled ice machine that is used for high volumes of ice creation can use up to 4,900 litres per day, which is a massive amount of water usage. Rather than using a tradition ice machine, why not install an air-cooled model? These models can save up to 40,000 litres per year for a 250 kg machine. Another option is to go iceless for drinks that do not need it, such as cold water from the fridge, which is already refreshing in and of itself.

Reuse greywater

Many restaurants have green surrounds with foliage and plants that need watering and care. This is one way to reuse the water that may have been used to mop floors or wash dishes. Save this water and reuse it for watering plants or for flushing staff toilets. If you are planning on using greywater to water your plants, it is important to ensure that there is no salt in the water, as this can affect some species.

Rain catchments

Installing a tank to catch rain is a highly eco-friendly and efficient way to save water in any restaurant. This water can be used for washing dishes and floors, as well as watering any landscaping or gardens your grounds may have. Rainwater also costs nothing, so utilising this water will save you money as well as being highly sustainable.



If you want to become a more sustainable and water conscious restaurant, it is important to start small, as making drastic changes first may not be successful or manageable over time. Make small changes to your water usage systems and then graduate to more in-depth solutions. Implementing highly technological water filtration systems is a vital way to sustain any water management strategies you have in place.
