🏢 Multifamily Water Cost Analysis

Why Apartment & HOA Properties Overpay for Water

Master-metered multifamily properties pay 100% of every gallon consumed by tenants who have zero financial incentive to conserve. The result is structurally higher consumption — and structurally higher bills — that Smart Valve™ reduces without any tenant behavior change.

The Master Meter Problem

One Meter, One Bill — Paid Entirely by the Owner

Most multifamily properties are master-metered: one commercial meter for the entire property, billed to the owner. Tenants pay a flat utility allowance or nothing — they have no financial incentive to conserve water.

Master-Metered Properties Consume More

Water consumption in master-metered properties is consistently higher than in individually metered properties. Tenants who don't pay the water bill take longer showers, run dishwashers half-full, and ignore dripping faucets.

The Owner Absorbs 100% of Every Dripping Faucet

Every dripping faucet, running toilet, and long shower in the building is 100% absorbed by the property owner. The aggregate effect of tenant behavior across 50, 100, or 300 units is substantial — and it compounds with every rate increase.

Smart Valve™ — No Behavior Change Required

Smart Valve™ reduces metered consumption at the supply line — before it reaches tenant units. No behavior change required from tenants. The reduction is mechanical, not behavioral, and it applies to every gallon consumed regardless of tenant actions.

★ THE MATH — 100-UNIT PROPERTY

A 100-Unit Property by the Numbers

100 units × 1.5 persons/unit = 150 residents
150 residents × 85 gal/day = 12,750 gal/day
12,750 × 30 days = 382,500 gal/month
At $0.006/gal = ~$2,295/month water alone
Plus sewer (80–120% of water) = $4,000–$5,000/month combined
15% Smart Valve™ savings = $600–$750/month = $7,200–$9,000/year
$21,600–$27,000/yr minimum
At 15% guaranteed savings — 300-unit property

Rate Increases Compound the Problem

5% Rate Increase = $9,000 More Per Year on a $15K/Month Bill

Every 5% municipal rate increase on a $15,000/month water bill adds $9,000/year to operating costs — without any change in consumption. Multifamily owners cannot pass these increases to tenants mid-lease in most markets.

Locked-In Percentage Saves More Every Year Rates Rise

A 15% reduction locked in today saves 15% off a higher number every year rates increase. The absolute dollar value of a fixed percentage reduction grows automatically as rates rise — without any additional investment or action.

Smart Valve™ Cuts the Underlying Consumption

By reducing metered consumption, Smart Valve™ makes each future rate increase less damaging in absolute dollar terms. The higher the rate, the more each saved gallon is worth.
