Don’t Just Guess, Assess: A Guide to Water Efficiency Audits
By Brian on August 5, 2025

Why a Water Audit is a Smart Business Move
Ever wonder where all your water goes? A water efficiency audit is your best tool to find out.
Here’s why a water efficiency audit is key for homes and businesses:
- Identifies Hidden Waste: Uncovers leaks, inefficient fixtures, and wasteful practices you might not even know about.
- Saves Money: Directly leads to lower water bills and often energy savings too (e.g., heating less water).
- Boosts Sustainability: Helps conserve a precious resource, showing your commitment to the environment.
- Pinpoints Opportunities: Gives you a clear roadmap for smart water-saving upgrades and changes.
Across Northern California and the globe, rising utility costs and water scarcity are major concerns. For property owners, effective water management isn’t just about cutting expenses; it’s about responsible stewardship of our natural resources.
Go Pro Plumbing understands these challenges. We provide practical solutions that make a real difference. An audit provides clarity, turning guesswork into a smart, data-driven approach to water management. It’s the first step to taking control of your water use, reducing your environmental footprint, and improving your bottom line.
Basic water efficiency audit terms:
A water efficiency audit is more than a quick look at your pipes; it’s a systematic process to identify how water is used, where it’s wasted, and how to optimize usage. This is smart resource management that directly impacts your operational costs.
Many businesses and large residences waste significant water. This “non-revenue water”—water lost before its intended use—drains your budget. A thorough water efficiency audit pinpoints these hidden losses from leaks, inefficient equipment, or outdated practices.
The savings potential is substantial. Studies show a comprehensive water efficiency audit can cut water consumption by 20% to 50%. For our clients in Rancho Cordova and Sacramento, this is an achievable reality. Beyond financial relief, reducing your water footprint contributes to a sustainable future, aligning with global efforts like the partnership between The World Bank and the International Water Association to Establish a Partnership to Reduce Water Losses that highlights the importance of worldwide water conservation.
Key Benefits for Your Bottom Line and Brand
A water efficiency audit is one of the smartest decisions for your property.
The undeniable financial savings are just the beginning. Reducing water use often cuts energy use, as less hot water needs heating. This creates a double-whammy of ongoing savings that improve your profitability year after year.
An audit also improves your public image. Consumers and partners prefer businesses that demonstrate environmental responsibility. Pursuing water efficiency showcases your commitment to sustainability, enhancing your brand and attracting environmentally conscious clients.
Furthermore, a water efficiency audit helps you achieve sustainability targets. Many organizations have goals to reduce their environmental impact. An audit provides the data and insights to meet and exceed these targets, demonstrating measurable progress.
Finally, an audit is proactive maintenance. Identifying leaks or failing equipment early prevents them from becoming costly emergencies. This foresight prevents property damage, reduces future repair costs, and can contribute to an increased property value, making the property more attractive to buyers or tenants.
Understanding Different Audit Levels
Not every water efficiency audit needs to be an exhaustive undertaking. We tailor our approach to your specific needs, offering different levels of investigation at varying costs.
Audit Level | Description | Focus | Best For |
---|---|---|---|
Preliminary Walk-Through | A high-level visual inspection and review of water bills. Identifies obvious leaks, major inefficiencies, and provides a general understanding of water use. Often relies on readily available data and visual cues. | Quick identification of “low-hanging fruit” and major anomalies. | Properties looking for initial insights, quick wins, or to gauge the potential for savings before committing to a more detailed study. Ideal for smaller commercial properties or larger residences. |
Detailed Engineering Analysis | A more in-depth investigation involving comprehensive data collection, flow measurements, detailed equipment inventories, and engineering calculations. This level quantifies specific end uses and losses with a higher degree of accuracy. Often includes a full water balance. | Precise quantification of water use, identification of all significant loss points, and detailed ROI calculations for specific measures. | Larger commercial, industrial, or multi-family residential properties with significant water use, complex systems (e.g., cooling towers, process water), or those seeking substantial, long-term savings and precise payback periods for investments. Often aligns with ASHRAE Level II. |
ASHRAE Levels | ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) provides a widely recognized standard for energy audits, which often include water. | Standardized methodology for comprehensive analysis. | Businesses or institutions requiring a formal, industry-standard audit report, often for compliance, certification, or to secure financing for efficiency upgrades. |
Lower Detail vs. Detailed Investigations | This refers to the spectrum between the preliminary and detailed audits. A lower detail investigation might be a focused check on a specific system (e.g., irrigation), while a detailed one covers the entire property. | Customization based on specific areas of concern or budget. | Any property type where a full comprehensive audit might be overkill initially, but a targeted investigation is warranted. |
Choosing the right audit depends on your goals, property complexity, and budget. For many Northern California clients, a preliminary walk-through is an excellent starting point. From there, we can determine if a more detailed analysis is needed for greater efficiencies. We’ll guide you to ensure you get the most value from your water efficiency audit.
How to Conduct a Comprehensive Water Efficiency Audit
A comprehensive water efficiency audit is more than just finding leaks. It’s a process to understand your property’s entire water story. We gather data, perform on-site inspections, balance your water budget, and determine where every drop goes. The goal is to create a clear plan for real, measurable savings.
At Go Pro Plumbing, we handle this process with great care, ensuring no stone (or leaky pipe!) is left unturned.
Step 1: The Preliminary Water Efficiency Audit – Data Gathering
The first step, data gathering, is the foundation of your water efficiency audit and begins before we visit your property.
First, we analyze 12 to 24 months of your water bills to establish a baseline of your typical water habits. By identifying usage trends and plotting monthly data, we can spot unusual patterns that might indicate leaks or seasonal spikes. We also review your utility rate structures to understand your costs.
Next, we review your building plans or schematics. These are helpful for understanding your plumbing system and locating major water-using areas.
Finally, we work with you to create an equipment inventory of all major water-using systems, such as toilets, urinals, faucets, showerheads, washing machines, dishwashers, cooling towers, and irrigation systems. This information helps us plan our on-site inspection.
Step 2: The On-Site Walk-Through and Inspection
The on-site walk-through is a vital part of the water efficiency audit. Our experts act as detectives, seeing your water use up close to find problems that bills alone can’t reveal.
One of our main goals is leak detection. We look for visible leaks and listen for the quiet hiss of hidden leaks behind walls or underground. We’ll check all accessible pipes, connections, and fixtures. Even a small drip can waste thousands of gallons over time!
A single dripping faucet can waste thousands of gallons of water per year. Every drop counts!
We carefully measure fixture flow rates. For faucets and showerheads, we use special tools to see how many gallons per minute (GPM) they use. For toilets, we might use the bucket and stopwatch method or perform dye tests for toilets to find “silent leaks” from the tank into the bowl. If dye appears in the bowl without flushing, you have a leak.
We also perform a thorough assessment of equipment, checking the efficiency of toilets, faucets, cooling towers, and irrigation systems. Our trained technicians look for everything from worn-out parts to improperly configured systems.
Step 3: Calculating Your Water Balance
After collecting data, we quantify end uses and build a detailed water balance. This is like a financial statement for your water, tracking where every gallon goes.
Our goal is to account for all the water that enters your property and figure out how it’s used or lost. This helps us find “unaccounted-for water,” which is often the biggest clue to hidden leaks or inefficiencies.
A water balance typically looks at a few key things:
- System Input: The total amount of water that comes into your property, usually measured by your main water meter.
- Authorized Consumption: The water you actually use for its intended purpose – like for restrooms, kitchens, irrigation, or industrial processes.
- Water Losses: This is where we find out where water is being wasted. Losses generally fall into two categories:
- Apparent Losses: These are errors in measuring or unauthorized use, such as metering errors or theft.
- Real Losses: These are physical losses of water from your system, including leaks from pipes and fixtures or overflows from tanks.
By comparing your total consumption and losses to your system input, we pinpoint your “unaccounted-for water.” A high number here tells us where to focus our efforts for immediate action.
We use methods like the AWWA/IWA methodology and tools like the AWWA Free Water Audit Software© to standardize calculations. Our trained experts use these methods to provide the most precise water balance possible.
From Audit to Action: Implementing and Monitoring Savings
A water efficiency audit is a personalized roadmap to real savings. The magic happens when we transform insights into concrete actions that put money back in your pocket.
After your water efficiency audit, the Go Pro Plumbing team helps you prioritize repairs for the biggest impact. We’ll target issues like hidden leaks costing you hundreds monthly or old toilets flushing money down the drain.
As experienced professionals, we know which fixes to tackle first. Retrofitting fixtures may seem expensive, but the savings from replacing a single old toilet are compelling. We also identify simple process improvements, like adjusting irrigation schedules, that require no new equipment.
But here’s where it gets exciting: monitoring results and calculating ROI. There’s nothing quite like seeing your first water bill after implementing our recommendations and watching those numbers drop!
Common Water-Saving Measures and Their Impact
Across Northern California, our water efficiency audits consistently show which improvements deliver the most dramatic results.
Low-flow fixtures are superstars of water savings. Old toilets can use up to 7 gallons per flush, while today’s high-efficiency models use 1.28 gallons or less. Modern showerheads can cut water use from 5 GPM down to 2 GPM while improving the shower experience.
For our commercial clients, cooling tower optimization is where we often find the biggest opportunities. With proper management, we’ve helped businesses cut their cooling water use by 30% or more.
Smart irrigation controls are ideal for drought-prone Northern California. These systems check weather forecasts and soil moisture to water automatically and only when needed, preventing waste.
Rainwater harvesting and reusing process water are becoming increasingly practical and can make a noticeable dent in your water bills.
Here’s the kicker: leak repair payback is almost always our fastest winner. We’ve seen clients save their entire repair cost within the first month just by fixing a hidden toilet leak.
Understanding the Results of Your Water Efficiency Audit and Tracking Success
Reviewing the audit report with you is a key part of the process where everything clicks into place.
We explain every finding in plain English so you understand where your water dollars are going. Then, we work with you on setting reduction goals that fit your situation, like cutting your water bill by 30% in six months or meeting a sustainability target.
Continuous monitoring becomes second nature once you see how satisfying it is to track your progress. Comparing new bills to baseline data from before the audit gives you concrete proof of your savings. We teach our clients how to spot the trends and celebrate the wins.
We also help with normalizing data. If business was busier or a hot summer required more irrigation, we adjust the numbers to show your true efficiency gains.
Don’t underestimate the power of employee feedback. When staff members know about the water-saving efforts, they become your best allies in spotting new leaks or suggesting improvements. It creates a culture where everyone feels invested in the success.

Frequently Asked Questions about Water Audits
We get a lot of thoughtful questions from our clients about water efficiency audits. Let’s tackle the most common ones together.
What is the typical cost and return on investment for a water audit?
Audit costs vary. A basic assessment for a small home or business might be a few hundred dollars, while audits for large, complex properties can run into the thousands.
What really matters is the savings. Most of our clients see payback periods under 1-2 years, after which the audit provides ongoing monthly savings.
The savings potential is exciting, with many properties seeing 30-60% reductions in water use. For example, Philadelphia’s efficiency programs have saved millions of gallons, and the University of Tennessee saw dramatic results from its audit and upgrades.
Think of it this way: you’re not spending money on an audit, you’re investing in long-term value. The savings keep coming year after year, making it one of the smartest investments for your property.
How do water audits differ for commercial, industrial, and residential properties?
While every water efficiency audit follows the same basic approach, the details differ by property type.
For commercial properties like offices or restaurants, we focus on high-use areas like restrooms, kitchens, and landscaping. The number of people using the space heavily influences water patterns.
Industrial properties are where things get really interesting. Manufacturing and food processing facilities use water for cooling, processing, and cleaning on a massive scale. We look for opportunities to reuse and recycle water within your processes. The volumes are typically much higher, but so are the potential savings.
Residential properties are simpler but no less important. We check your fixtures, appliances, and irrigation—toilets, showers, washing machines, and sprinklers. Leak detection is critical here, as one running toilet can quietly waste thousands of gallons.
At Go Pro Plumbing, we’ve worked with everything from single-family homes in Sacramento to large commercial facilities in Rancho Cordova. We know how to customize our approach to get you the best results.
What role do employees or residents play in a successful audit?
The people using water daily are crucial for the long-term success of a water efficiency audit. While we fix technical problems, the human element makes the real difference.
Reporting leaks is one of the biggest ways people can help. An unreported dripping faucet or running toilet can waste incredible amounts of water. When everyone reports issues, problems get fixed fast.
Everyday water-conscious habits also add up. Turning off faucets while washing hands, taking shorter showers, and running full loads in appliances create impressive collective savings.
We love it when people suggest improvements. Employees and residents often notice things we might miss, like which faucets always drip or where water gets wasted in daily operations.
The real magic happens when you foster a conservation culture. This means ongoing communication, celebrating successes, and making conservation a team effort.
For businesses, basic training and awareness sessions can work wonders. When people understand how their choices affect the bottom line and the environment, they become part of the solution.
Go Pro Plumbing provides the technical audit roadmap, but the people in your space are key to making savings last.
