Water. We all need it. Which is why in today’s eco-conscious world, sustainability is more than a buzzword. Water conservation can and should be a driving force behind customer loyalty and business profitability. But only if you understand how the carwash industry is uniquely positioned to lead in water conservation efforts.
This article is based on Water Conservation Untapped, an informative NCS webinar. It outlines key strategies for optimizing water use while delivering exceptional service. The goal is to reduce both operational costs and environmental impact.
Understanding Water Usage in Carwashes
Water is the lifeblood of carwash operations, but conserving this resource is crucial. It’s not uncommon for carwashes to consume anywhere from 80 to 100 gallons per vehicle if not optimized. Home car washes can waste up to 150 gallons per wash, with soapy water running directly into storm drains, impacting local waterways.
By contrast, professional carwashes properly equipped can reduce water usage to as low as 20 to 30 gallons per car. But efficient water management is not just about reducing fresh water input; it’s about minimizing wastewater as well. With sewer costs three to seven times higher than freshwater costs, it’s valuable to conserve water on both the input and output side.
Reclaim Systems: Recycling Water for Sustainability
Reclaim systems capture, filter and reuse water within the carwash. This process significantly reduces the demand for freshwater and lowers sewer costs. High-quality reclaimed water can be used for several cycles within the wash process, including pre-wash, main wash and wheel cleaning. When implementing reclaim systems, it’s essential to:
- Use high-quality purification systems and filters to remove impurities
- Regularly monitor for cloudiness or foul odors, which can indicate a system issue
- Invest in chemistry solutions designed to be reclaim friendly
Reverse Osmosis (RO) Systems: The Key to Spot-Free Rinses
RO systems purify water by removing dissolved solids, ensuring a high-quality, spot-free rinse. These systems have become increasingly efficient, improving from a 1:1 water ratio to 3:1 or even 4:1, meaning less water is wasted during purification. To optimize an RO system:
- Maintain a TDS (Total Dissolved Solids) level below 25 parts per million for optimal results
- Regularly test TDS levels and adjust the system as needed
- Ensure RO water is used in final rinse stages to enhance customer satisfaction
Beyond advanced systems, there are simple yet impactful adjustments that carwash operators can make:
- Conveyor Speed and Timing: Ensure that spray systems activate only when vehicles are in place to avoid unnecessary water use.
- Nozzle Optimization: Use nozzles and applicators designed for specific stages of the wash. This ensures optimal water dispersion and prevents overuse.
- Water Softener Programming: Properly calibrating water softeners to local water hardness levels can prevent excessive salt and water use.
The Role of Chemistry in Water Conservation
Selecting the right carwash chemicals plays a critical role in water conservation. Ultra-concentrated, reclaim-friendly formulas can enhance cleaning while maintaining water quality. Avoid chemicals containing mineral oils or non-biodegradable surfactants that can degrade reclaim water and clog systems.
Monitoring and Maintenance: The Key to Long-Term Savings
Implementing monitoring systems, such as cloud-based platforms, can provide real-time updates on system performance, alert operators to issues like reclaim system shutdowns, and schedule maintenance reminders. Consistent oversight ensures that reclaim and RO systems remain efficient, minimizing water loss and preventing unexpected sewer costs.
Educating Customers and Enhancing Engagement
Customer education is vital for building brand loyalty and showcasing sustainability efforts. Inform customers about the environmental benefits of professional carwashes compared to home washing. Display water savings metrics at your site, such as, “By choosing us, you’ve saved 70 gallons of water per wash compared to washing at home!” Creating an interactive experience, like water conservation trackers or community partnerships, can foster a sense of pride among customers.
Employee Engagement and Training
Well-trained employees are crucial for efficient water use. Equip staff with the knowledge to detect issues early, such as identifying cloudy reclaim water or increased labor requirements for equipment cleaning. Offering professional development opportunities, such as sustainability workshops, can boost retention and morale. Employees who understand the broader impact of water conservation are more likely to take ownership of these initiatives.
Community Involvement: Strengthening Your License to Operate
Building strong community ties through conservation events, educational outreach, and partnerships can enhance your carwash’s reputation as an environmental steward. Consider hosting water education events or partnering with local schools and civic organizations to spread awareness about water sustainability.
Case Study: A Real-World Example
A large carwash chain facing rising water and sewer costs implemented several conservation measures after conducting a site audit. By optimizing reclaim systems, reconfiguring nozzles, and repairing inefficiencies, the company achieved significant cost reductions:
- An initial $9,000 investment in system repairs resulted in $35,000 in annual savings.
- Renozzling efforts led to a tenfold return on investment, reducing cost-per-car expenses by 30%.
These results highlight the importance of a proactive approach to water management.
Customer Perceptions and Industry Trends
Research shows that while customers believe professional carwashes are environmentally responsible, they often feel uninformed about specific sustainability efforts. Bridging this gap through clear communication can boost satisfaction and differentiate your business. Additionally, studies indicate that younger consumers, particularly those aged 18-34, are willing to pay more for sustainable services, making it crucial to align your marketing with these values.
Actionable Steps for Immediate Impact
To get started with water conservation today, consider the following steps:
- Calculate Your Cost Per Car: Use tools to determine your water and sewer expenses per vehicle.
- Review System Timing: Ensure that wash cycles align with vehicle positions.
- Check Water Softener Settings: Adjust settings to match your site’s water hardness.
- Monitor TDS Levels: Regularly test and adjust RO systems to maintain optimal water quality.
- Optimize Nozzles and Applicators: Work with equipment representatives to ensure nozzles are correctly positioned and calibrated.
Work With the Best – Make Every Drop Count
Water conservation in carwashes is not only an environmental imperative but also a smart business strategy. By implementing advanced systems, fine-tuning operations, educating customers, and engaging employees, carwash operators can achieve significant cost savings while making a meaningful contribution to sustainability.
