What bills should the baseline include?
Start with 12–24 months of water and sewer bills so the comparison captures rate changes, seasonality, occupancy, and the annual operating expense at stake.
Commercial Buildings
Calculate commercial building water savings and ROI.
Use your building's water and sewer bill, service-line details, expected valve size, and cap rate to estimate annual savings, payback, and NOI impact. Built for office, mixed-use, retail, and institutional properties; a site assessment verifies the model before any recommendation.

Why owners and operators evaluate it
Commercial buildings need operating-expense reductions that do not create tenant disruption or operational complexity. Flumera starts with utility bills and a site-access check, then turns that into a practical savings proposal.

Assessment path
1
Send utility bills
We use recent water and sewer bills to estimate the savings opportunity.
2
Capture site details
Meter, pipe, and access details determine sizing and install scope.
3
Review proposal
The final proposal lays out savings, payback, guarantee, and options.
Water-savings economics
Model the operating-expense opportunity
Enter the expected valve size, current water and sewer bill, and property cap rate to compare annual savings, payback, and potential property-value impact. The estimate is a starting point; the site assessment verifies bills, service lines, access, and operating conditions.

Commercial water analysis
Build the estimate from evidence, not a generic percentage
A defensible commercial building water-savings model separates utility-rate changes from consumption and connects the bill to the physical service line and operating conditions.
What building details affect the estimate?
Record every incoming service line, meter and pipe size, pressure range, access, and recent plumbing or meter work. These details determine fit and installation scope.
How are savings and ROI calculated?
The calculator applies a modeled reduction to the current water and sewer expense, compares annual savings with valve cost, and divides annual savings by cap rate to illustrate potential NOI-related property value.
Can rate increases look like higher usage?
Yes. Compare billed volume and unit rates separately before attributing a higher bill to consumption. Estimated reads, adjustments, minimum charges, and sewer treatment also need review.
Does the estimate require tenant changes?
No behavior change is assumed in the calculator. The site assessment evaluates the owner-paid account and building infrastructure without assigning savings to fixture or tenant programs.
What turns an estimate into a proposal?
Flumera verifies bills, meter and pipe information, access, operating changes, and measurement terms before recommending a valve or presenting property-specific economics.
