Water is consistently one of the largest controllable operating expenses at a multifamily property - and one of the most underoptimized. Unlike rent growth or expense categories that require market conditions to change, water consumption is something operators can directly influence through targeted programs.
The math is more compelling than most operators realize.
The Numbers
A 200-unit property using 50 gallons per unit per day at a blended water and sewer rate of $10 per thousand gallons spends approximately $365,000 annually on water. A 15% reduction in consumption saves roughly $55,000 per year - at a 5% cap rate, that’s over $1 million in asset value created from a conservation program.
Those numbers vary significantly by market, property type, and current consumption levels. But the principle holds across almost every multifamily scenario: water savings flow directly to NOI, and NOI improvements are multiplied in asset value.
The Most Effective Conservation Interventions
Low-Flow Fixture Installation
Replacing standard fixtures with low-flow alternatives - showerheads, faucet aerators, and toilets - is the highest-impact, lowest-disruption conservation intervention available. Low-flow showerheads and faucet aerators deliver meaningful reductions in consumption without impacting resident experience.
Annual Retrofit Maintenance
Low-flow fixtures degrade over time. Showerheads accumulate mineral deposits that reduce flow restriction effectiveness. Toilet flappers fail and create phantom leaks. An annual retrofit maintenance program that inspects and replaces components as needed is what separates a conservation program that performs year after year from one that delivers first-year savings and then slowly erodes.
In-Unit Leak Detection
A single running toilet can waste 200 gallons per day. Multiplied across a 200-unit property where 5–10% of units have unreported leaks at any given time, the waste is substantial - and invisible without a systematic inspection program. Annual in-unit leak detection, performed as part of retrofit maintenance, catches and eliminates this waste.
Green Lending Compliance
Properties that meet energy and water efficiency standards qualify for green lending programs through Fannie Mae, Freddie Mac, and other lenders. These programs offer interest rate reductions and other favorable terms that can significantly improve the economics of a conservation investment. We structure programs to meet these standards where applicable.
We’ll give you an honest assessment of what a program looks like for your specific property - including realistic savings projections based on your current consumption data and local utility rates. Project timelines depend on inventory availability, which we’ll communicate upfront.
