Cutting Costs and Conserving Water in Commercial Kitchens

11 min read

Water conservation in commercial kitchens isn’t just about saving money—it’s about sustainability and responsibility. As someone who’s spent countless hours in both bustling restaurants and cozy home kitchens, I’ve seen firsthand how much water can be wasted. But here’s the thing: with a few smart strategies and some modern equipment, you can significantly reduce your kitchen’s water footprint. Let’s dive into some practical tips and tools to help you save water and cut costs without compromising your operations.

I remember when I first moved to Nashville from the Bay Area, the difference in water usage policies struck me. Nashville has its own unique challenges and opportunities when it comes to sustainability. So, let’s explore how you can make a real difference in your commercial kitchen.

In this article, we’ll cover everything from simple behavioral changes to advanced equipment upgrades. By the end, you’ll have a comprehensive understanding of how to transform your kitchen into a water-saving powerhouse. So, grab a coffee (or tea, if that’s your thing), and let’s get started.

The Basics: Behavioral Changes and Quick Wins

Before we dive into the world of high-efficiency appliances and advanced water-saving technologies, let’s start with the basics. Simple changes in behavior and habits can make a big difference in your water usage. Plus, these changes often come at little to no cost. It’s a win-win.

Train Your Staff

Educating your staff on water conservation is the first step. Make sure everyone knows the importance of saving water and understands their role in making it happen. You could even create a water conservation policy to formalize your commitment.

Here are some quick wins to include in your policy:

  • Turn off taps completely after use. A dripping tap can waste gallons of water daily.
  • Scrape dishes before washing to minimize pre-rinse needs.
  • Use appropriate glassware and dishware sizes to reduce washing needs.
  • Thaw food in the refrigerator overnight instead of using running water.

But is this enough? Let’s consider the bigger picture.

Optimize Your Dishwashing

Dishwashing is one of the most water-intensive activities in a commercial kitchen. Luckily, there are plenty of ways to optimize this process. For starters, always run your dishwasher at full capacity. This might seem obvious, but it’s easy to overlook during busy services.

Next, think about your washing methods:

  • For pre-rinse, use a scraper to remove food waste before washing.
  • Consider a dipper well—a small sink used to rinse utensils—to reduce water usage.
  • If possible, install a recirculating system to reuse rinse water.

And what about the dishwasher itself? Let’s explore that next.

Upgrading Your Equipment: Dishwashers and Beyond

If you’re serious about water conservation, investing in high-efficiency equipment is a must. Yes, it requires upfront capital, but the long-term savings and environmental benefits make it worthwhile. Plus, you might qualify for rebates or incentives, but more on that later.

High-Efficiency Dishwashers

Modern high-efficiency dishwashers use significantly less water than older models. They achieve this through advanced spray arm technology, improved filtration, and smart wash cycles.

When shopping for a new dishwasher, look for the following features:

  • Energy Star certification: This indicates the dishwasher meets strict energy and water efficiency guidelines.
  • Low water consumption: Look for models that use 1 gallon per rack or less.
  • Multiple wash cycles: This allows you to choose the most water-efficient cycle for each load.

But which dishwasher to choose? There are countless options out there, but for my money, you can’t go wrong with a high-efficiency model from Chef’s Deal. They offer a great range of commercial dishwashers that tick all the boxes.

Ice Machines

Ice machines can be another water hog in your kitchen. Traditional models can use up to 100 gallons of water to produce just 100 pounds of ice. That’s a lot of wasted water.

Enter water-cooled ice machines. These models reuse water to cool the condenser, reducing overall water consumption. Plus, they tend to be more energy-efficient, too.

But maybe you’re not ready to replace your ice machine. In that case, consider these water-saving tips:

  • Regular maintenance: Keep your ice machine clean and well-maintained to ensure optimal water usage.
  • Air-cooled condenser: If possible, switch to an air-cooled condenser to reduce water consumption.
  • Water filtration: Install a water filter to remove impurities and reduce the need for frequent cleaning.

Okay, so we’ve covered dishwashers and ice machines. But what about the humble faucet?

Low-Flow Faucets and Aerators

Installing low-flow faucets and aerators is one of the easiest and most cost-effective ways to reduce water usage in your commercial kitchen. These devices work by mixing air with water, reducing the flow rate without compromising performance.

Here are some quick facts about low-flow faucets and aerators:

  • Standard faucets flow at around 2.2 gallons per minute (gpm). Low-flow faucets reduce this to 1.5 gpm or less.
  • Aerators can be easily installed on existing faucets, making them a great option for retrofitting.
  • Look for faucets and aerators with a WaterSense label. These meet EPA criteria for water efficiency.

But are these upgrades enough? Maybe, maybe not. It depends on your kitchen’s unique needs and circumstances. But one thing’s for sure: every little bit helps.

The Big Guns: Advanced Water-Saving Technologies

So, you’ve implemented behavioral changes and upgraded your equipment. What’s next? It’s time to bring out the big guns: advanced water-saving technologies.

Water Recycling Systems

Water recycling systems collect, treat, and reuse water for various purposes. In a commercial kitchen, this could mean using recycled water for tasks like floor cleaning, toilet flushing, or even irrigation if you have an outdoor space.

Here’s how it works:

  1. Water is collected from sources like dishwashers, ice machines, and HVAC systems.
  2. The water is then treated to remove impurities and contaminants.
  3. Finally, the treated water is stored and reused as needed.

Sounds great, right? But is it feasible for your kitchen? That depends. Water recycling systems can be a significant investment, and they require regular maintenance. But if you’re serious about sustainability, they’re worth considering.

Rainwater Harvesting

Speaking of water recycling, have you considered rainwater harvesting? This involves collecting and storing rainwater for later use. It’s a fantastic way to reduce your reliance on municipal water supplies and save money in the process.

Here are some potential uses for harvested rainwater in a commercial kitchen:

  • Landscaping and irrigation
  • Toilet flushing
  • Cleaning and maintenance tasks
  • Cooling towers and HVAC systems

But before you rush out and install a rainwater harvesting system, do your research. You’ll need to consider factors like rainfall patterns, storage capacity, and local regulations.

Smart Water Management Systems

Finally, let’s talk about smart water management systems. These high-tech solutions use sensors, data analysis, and automated controls to monitor and optimize water usage in real-time.

Here’s what you can expect from a smart water management system:

  • Real-time water usage monitoring
  • Leak detection and automated shut-off
  • Data analysis and reporting
  • Automated water-saving recommendations

Is this the future of water conservation in commercial kitchens? Maybe. But like any advanced technology, it comes with a significant price tag. You’ll need to weigh the potential savings against the upfront cost to determine if it’s right for your kitchen.

Incentives, Rebates, and Making the Numbers Work

So, you’re convinced that investing in water-saving technologies is the right move. But how do you make the numbers work? Luckily, there are plenty of incentives and rebates available to help offset the cost.

Local and Federal Incentives

Many local and federal governments offer incentives for businesses that invest in water-saving technologies. These can come in the form of tax credits, rebates, or low-interest loans.

Here are some resources to help you find incentives in your area:

  • Database of State Incentives for Renewables & Efficiency (DSIRE): A comprehensive resource for state, local, utility, and federal incentives.
  • EPA WaterSense Program: Offers rebates and other incentives for WaterSense-labeled products.
  • Local Water Utility: Many local water utilities offer rebates and other incentives for water-saving upgrades.

But it’s not just about the money. These incentives also send a clear message: water conservation is a priority, and businesses that invest in it will be rewarded.

Return on Investment (ROI)

Of course, even with incentives, investing in water-saving technologies requires upfront capital. So, you’ll want to ensure you’re getting a solid return on investment (ROI).

Here’s how to calculate ROI for water-saving upgrades:

  1. Estimate the annual water savings from the upgrade.
  2. Determine the annual cost savings based on your current water rates.
  3. Calculate the total cost of the upgrade, including equipment, installation, and maintenance.
  4. Divide the annual cost savings by the total cost of the upgrade to determine the ROI percentage.

And remember, ROI isn’t just about money. It’s also about the environmental benefits, the message you send to your customers, and the peace of mind that comes with knowing you’re doing the right thing.

Making the Case

Finally, you might need to make the case for water-saving upgrades to your boss, your investors, or even your staff. Here are some tips to help you build a compelling argument:

  • Focus on the long-term benefits, not just the upfront costs.
  • Highlight the environmental impact of water conservation.
  • Use data and real-world examples to illustrate your points.
  • Emphasize the reputational benefits of being a sustainable business.

And if all else fails, remind them that water is a finite resource. We all have a responsibility to use it wisely.

Beyond the Kitchen: Holistic Water Conservation

So far, we’ve focused on water conservation within the kitchen. But what about the rest of your operation? Taking a holistic approach to water conservation can yield even greater savings.

Restrooms

Restrooms are another major water user in any commercial operation. Luckily, there are plenty of ways to save water in this area:

  • Install low-flow toilets and urinals.
  • Use motion-sensor faucets to prevent water waste.
  • Consider waterless urinals or composting toilets for even greater savings.

And don’t forget about leaks. A single leaky toilet can waste thousands of gallons of water each year. So, make sure to check your restrooms regularly for leaks and other water waste issues.

Landscaping

If your operation includes outdoor space, landscaping can be a significant water user. But it doesn’t have to be. Here are some water-saving landscaping tips:

  • Choose native, drought-resistant plants.
  • Use mulch to retain soil moisture and reduce water needs.
  • Install a smart irrigation system that adjusts watering based on weather conditions.
  • Consider rainwater harvesting or greywater recycling for irrigation.

And remember, a well-designed, water-efficient landscape can be a selling point for your business. It shows your customers that you care about the environment and are committed to sustainability.

Employee Engagement

Finally, don’t forget about your employees. Engaging your team in water conservation efforts can yield significant savings and foster a culture of sustainability.

Here are some ways to engage your employees in water conservation:
