Key Findings

26% reduction — among the highest in the NJ multifamily portfolio

At 26%, this is one of the strongest reductions recorded in any New Jersey apartment case study — consistent with similar small-building, 1" meter configurations where meter over-spin has the highest proportional impact.

8-month payback on a 1" meter installation

At $7.18/CCF combined water rate, the $3,566 annual savings generated a full return on investment in just 8 Months — well inside a single fiscal year.

No central AC — seasonally stable baseline

The absence of central air conditioning eliminates summertime HVAC-related water consumption variation, making the 26% reduction a direct measure of the Smart Valve™ effect on base consumption.

Occupancy constant — managing agent verified

Occupancy remained constant with minimal turnover throughout both measurement periods. Data sourced directly from the managing agent — not self-reported by ownership.
