For many commercial buildings, schools, airports, healthcare facilities, and office complexes, water costs involve more than paying for the water that comes out of the tap. Most utility bills include charges for both water consumption and wastewater treatment, commonly known as combined water and sewer billing.
As water and wastewater rates continue to climb across the United States, facility managers are looking for practical ways to reduce both costs. One of the most effective—and often overlooked—solutions is the installation of waterless urinals.
What Is Combined Water and Sewer Billing?
Combined water and sewer billing means a utility provider includes charges for both potable water delivery and wastewater collection on a single monthly invoice.
The concept is straightforward. Nearly every gallon of water entering a building eventually flows into the sewer system, where it must be collected, transported, and treated before being safely returned to the environment. Because these two services are connected, many municipalities combine them into one bill.
However, not every community uses the same billing structure. In some regions:
The city supplies just drinking water.
Another county or regional authority manages wastewater treatment.
Water and sewer services are billed separately, even though the costs remain linked.
Whether billed together or separately, reducing water consumption often lowers wastewater volumes as well.
Why Water and Sewer Costs Continue to Rise
Across North America, utilities face growing expenses related to:
Aging underground infrastructure
Population growth
Stricter environmental regulations
Drought and water scarcity
Increased treatment and energy costs
As a result, many commercial property owners are seeing annual increases in both water and sewer rates, making water efficiency investments more valuable than ever.
How Waterless Urinals Reduce Water and Sewer Charges
Unlike conventional urinals, waterless urinals require no flushing water. Instead, they use a specially engineered cartridge and liquid sealant that allows waste to pass while preventing sewer gases from escaping into the restroom.
Because they eliminate flush water entirely, waterless urinals generate savings in two important ways.
1. Significant Water Savings
A single waterless urinal can typically save 25,000 to 35,000 gallons of water each year, depending on building occupancy and the type of fixture being replaced.
For facilities with dozens—or even hundreds—of urinals, those savings can quickly reach hundreds of thousands or even millions of gallons annually.
2. Lower Sewer Charges
Every flush avoided also means less water enters the wastewater system.
Since many sewer utilities calculate fees based on water consumption, reducing flush water can lower sewer charges in addition to water charges. This creates a double financial benefit for facilities operating under combined billing systems.
Real Financial Benefits
Organizations that replace traditional flush urinals with waterless models frequently report measurable reductions in utility expenses.
For example, one California school district reduced its annual utility costs by approximately $1,700 after installing waterless urinals. Savings will vary by utility rates, occupancy levels, and the number of fixtures installed, but facilities with heavy restroom traffic often experience attractive long-term returns on investment.
Additional Benefits Beyond Utility Savings
While lower water and sewer bills are compelling, waterless urinals offer several additional operational advantages:
Reduced maintenance by eliminating flush valves, sensors, and related plumbing components
Improved restroom reliability with fewer moving parts that can fail
Excellent odor control when properly maintained with manufacturer-recommended cartridges and sealants
Support for sustainability initiatives including water conservation programs and green building objectives
Demonstrated environmental leadership that appeals to tenants, employees, visitors, and customers
The Bottom Line
Combined water and sewer billing reflects the close relationship between the water entering a building and the wastewater leaving it. As utility rates continue to rise, reducing water consumption has become one of the most effective ways to lower overall operating expenses.
Waterless urinals offer a practical solution by eliminating flush water altogether. The result is lower water usage, reduced sewer charges, fewer maintenance issues, and measurable environmental benefits. For facility managers seeking to improve sustainability while controlling operating costs, waterless urinals represent a smart investment that pays dividends year after year.
