Reprice the baseline
Apply the same provider, class, usage tiers, and applicable sewer rules to the baseline period.
Multifamily
Multifamily water management without tenant-unit retrofits.
A useful multifamily water management plan starts with the bill: who pays, which utility rates apply, and whether usage changes reflect occupancy, leaks, or building systems. Flumera is a building-level valve option evaluated near the main water meter, without unit-by-unit fixture replacement. Property-specific fit and savings need a documented baseline and site assessment.

Choose the right intervention
Leaks, fixtures, pressure, submetering, or a meter-side valve?
These approaches solve different problems. A high water bill alone does not establish entrained air or an inaccurate meter, and a valve is not a substitute for repairing leaks. Compare the building's evidence before selecting a project.
| Approach | What it addresses | What to verify |
|---|---|---|
| Leak detection and repair | Unwanted continuous consumption | Interval or overnight use, running fixtures, and repair records |
| Efficient fixtures | Water used by toilets, faucets, and showers | Existing flow rates, resident access, and replacement scope |
| Pressure management | Excess service pressure or pressure-related losses | Measured pressure, equipment requirements, and a licensed plumber's design |
| Submetering | Visibility into unit-level consumption and billing allocation | Plumbing layout, local rules, and tenant billing arrangements; allocation alone is not physical savings |
| Flumera valve assessment | A proposed reduction in billed volume under suitable meter and service conditions | Meter technology, supply conditions, installation access, and a controlled, normalized before/after comparison |

Illustrative bill analysis — not a customer case study
Separate rate increases from a change in usage
Suppose a property's annual variable water and sewer charges were $100,000. With a 6% rate increase and unchanged billed usage, they become $106,000. A hypothetical 10% reduction in billed volume at the new rate makes those variable charges $95,400: $10,600 below the unchanged-use scenario, but $4,600 below the prior-year amount.
Normalize operating changes
Document occupied unit-days, seasonality, repairs, irrigation, laundry, and other known demand changes.
Measure, then attribute
Compare billed volume and costs separately. A lower bill after several simultaneous projects does not establish one device's effect.
This example assumes proportional variable charges, with fixed fees excluded; real tiers, minimum charges, sewer caps, and return factors can change the result. The reduction is a modeled input, not a promised result. Check local rates in the interactive water-rate research and verify the tariff against a current property bill before a proposal.
Multifamily water management plan
Control the cost before measuring the result
Effective multifamily water management separates rate increases from consumption, identifies continuous use and leaks, and then evaluates building-level interventions against a documented baseline. This keeps savings claims tied to evidence instead of a generic portfolio assumption.
Build a property baseline
Compare 12–24 months of water and sewer bills, normalize for occupancy, and separate utility-rate changes from usage.
Find controllable demand
Review overnight consumption, common-area systems, irrigation, laundry, cooling, and recurring maintenance conditions.
Verify after installation
Compare post-install bills with the agreed baseline and document occupancy, repairs, seasonality, and other operating changes.
Where multifamily water costs accumulate
Owner-paid water and sewer expense is rarely driven by one factor. A useful review looks at the utility bill, the building's demand profile, and the physical service together.

Portfolio economics
Model water savings, payback, and NOI impact
Use the current owner-paid water and sewer bill to estimate the annual value of a modeled reduction. The calculator uses standard valve pricing; installation scope and property-specific savings are confirmed during the site assessment.

Fixed charges, minimums, and tariff tiers can change the relationship between volume and bill savings. Payback uses valve purchase price only and excludes installation. Capitalized value equals modeled annual savings divided by cap rate; it is not cash income, cash payback, or a property valuation. A site assessment verifies fit and assumptions.
Why multifamily owners care
Water and sewer costs flow directly through operating expenses. For owners, operators, and asset managers, a mechanical reduction in billed usage can improve monthly cash flow and strengthen NOI without a tenant education campaign.

Common questions
Multifamily water management FAQ
Does Flumera require work inside apartments?
No. The valve is evaluated for installation near the building's main water meter, so the project does not require unit-by-unit fixture replacement.
How are multifamily water savings measured?
Post-install bills are compared with a 12–24 month baseline and adjusted for documented variables such as occupancy, leaks, repairs, and seasonality.
Which buildings are the best candidates?
Owner-paid properties with meaningful water and sewer expense, accessible service lines, and reliable billing history are the clearest starting point.
