Smart Water Sensors: How Property Managers Are Catching Leaks and Cutting Water Waste

From fixture-level meters to motion-activated toilet shutoffs, here's what's new in water technology for multifamily properties.

Water is one of the hardest utilities to control in multifamily housing. Leaks run unnoticed behind walls and inside toilet tanks, and the bill arrives long after the water is gone.

The cost adds up quietly. A worn toilet flapper or a dripping fixture rarely gets reported, so the waste only shows up on the master bill weeks later, after the water is already paid for.

A new generation of smart water devices gives property managers better tools to see that waste, stop it, and bill for what's left fairly. Below, we break down the main options, and you can find exclusive discounts for Livable customers on our smart water solutions page.

Two Kinds of Water Technology

Smart water devices fall into two groups: some measure how much water each unit uses, and others stop water from being wasted in the first place. Many properties benefit from both.

Type What it does Best for Metering and leak detection Measures usage by unit or fixture and alerts you to leaks Billing residents on actual usage and catching leaks early Leak prevention Shuts off or limits water flow automatically at the fixture Cutting waste from running toilets, worn flappers, and long showers

 

Metering and Leak Detection

Submetering used to mean cutting pipes and calling a plumber. Newer devices clamp on or sit at the fixture, so properties can meter usage without major construction.

• DrizzleX: smart water monitors installed at individual fixtures detect leaks, identify water waste, and, according to DrizzleX, help multifamily properties reduce water consumption by 20 to 40%. The technology also supports usage-based resident billing, even in riser-plumbed buildings where traditional submetering isn't feasible.

• SimpleSUB Water: clamp-on ultrasonic meters that install in minutes with no pipe-cutting. They use built-in cellular with a 10-year battery and send 24/7 leak alerts.

Leak Prevention at the Fixture

Toilets are a common source of hidden waste. A worn flapper can leak silently for months, and residents often don't report it. Leak prevention devices stop that water before it reaches the meter.

• WaterWise: a motion-activated device that lets water reach the toilet only when someone is in the restroom. It stops silent leaks and overflows, works with existing tank toilets, and needs no plumbing replacement. WaterWise offers a free property analysis and pilot programs.

• The Water Scrooge: three devices that work together. A motion-activated toilet sensor that stops toilet leaks from running, a smart valve that, according to The Water Scrooge, removes air from the water line before the meter can register it as usage, and a shower flow controller installed behind the wall so residents can't remove it, locking in the flow rate. The Water Scrooge also offers a free savings analysis to show how much your property can save.

Both companies start with your property's water data to estimate savings before you commit.

Start With Your Water Data

The right mix of sensors depends on your buildings, your plumbing, and how much water you're losing today. Start by looking at your water bills to find the properties with the highest usage, then match the technology to the problem.

Did You Know?

The metering devices above don't just catch leaks. They also track water usage by unit or fixture, and that data can make resident billing more accurate.

Livable bills residents for water and other utilities, whether a property uses submeters, fixture-level meters, or a Ratio Utility Billing System (RUBS). Livable handles the billing, not the hardware, so you can choose the devices that fit your buildings.
