Why Is Water Multifamily's Hardest Operating Cost to Control?
For multifamily operators, water costs flow directly to NOI — there's no way to pass them to tenants in most markets. Smart Valve™ is a one-time expense that delivers permanent NOI improvement.
$50,000/Year — Grand Central Tampa
Grand Central at Kennedy in Tampa, FL achieved $50,000/year in verified annual savings with 23% metered water reduction. This is a large-scale multifamily complex — results are comparable to Class A properties in major US markets.
Rising Rates = Rising NOI Drag
Every 5% utility rate increase on a $15,000/month water bill costs $9,000/year in additional NOI drag. Smart Valve™ cuts the underlying consumption by 15–23%+ — permanently insulating you from rate escalations.
Resident operations review
The property team reviews pressure, flow, quality, access, and resident-service requirements before installation. Outcomes depend on site conditions.
Direct Cap Rate Improvement
A $50,000/year NOI improvement at a 5% cap rate increases property value by $1,000,000. Smart Valve™ is one of the few operational improvements that directly and immediately increases the appraisable value of a multifamily asset.
Property-by-property assessment
For multiple properties, AWS can review each meter, eligible charges, access, and operating requirements. Results and commercial terms vary by project.

Why do apartment complexes and multifamily properties pay more for water than they should?
Multifamily properties face a unique pressure challenge: dozens or hundreds of units cycling water on and off creates constant pressure fluctuations throughout the building's plumbing. Each fluctuation allows entrained air to expand in the service line and register on the meter as billable water. Master-metered properties — where the owner pays a single bill for the entire building — absorb 100% of this meter over-recording cost. A 100-unit apartment complex with unmanaged pressure typically sees 20–30% of its metered water volume attributable to air measurement and pressure-driven meter over-reading.
