Solutions
Pick your building. See where the savings are.
Stop paying for water nobody used
Running toilets and failed fill valves run around the clock in apartment buildings. NOWi catches them so maintenance can fix them before the next bill.
72% of buildings in one 1,789-unit Los Angeles portfolio were leaking in their first week on NOWi.
What it saves you
- Water and sewer on running toilets
- Maintenance hours spent hunting leaks
- Calls from owners about surprise bills
Typical setup: one Meter Monitor per building meter
No more water running all weekend
Offices and retail should go quiet at night and on weekends. NOWi tells you when they don’t.
You see exactly when a problem started, so your team isn’t guessing.
What it saves you
- Water running in an empty building
- Damage from leaks nobody saw
- Time spent explaining high bills
Typical setup: a Meter Monitor on the main meter
Separate guest use from waste
Hotels use a lot of water on purpose. NOWi finds the leak hiding underneath normal guest use.
NOWi data has helped find water savings at some of the largest hotels in Toronto.
What it saves you
- Waste hidden under normal guest use
- Rooms out of service from water damage
- Engineering time on slow leaks
Typical setup: Meter Monitors per building
Know where your process water goes
See water by line, not as one monthly total, and catch a line that draws water it shouldn’t.
Clamps on, so there’s no cutting pipes or stopping production.
What it saves you
- Process water nobody accounted for
- Downtime from failed lines
- Surprises in the utility budget
Typical setup: Pipe Monitors on key lines
Catch a stuck valve before it runs all night
One stuck solenoid can run thousands of gallons after close. NOWi alerts when water flows outside your hours.
Scheduled usage reports keep every site manager looking at the same numbers.
What it saves you
- Water lost to stuck valves after close
- Repeat service calls
- Margin lost to the water bill
Typical setup: a Meter Monitor on the site meter
Stop paying for cooling tower overflow
Cooling towers are among the biggest water users in a building. NOWi watches makeup and blowdown so overflows don’t run for weeks.
Clamp-on, so it goes onto existing lines with no shutdown.
What it saves you
- Makeup water lost to overflows
- Treatment chemicals lost with it
- Water lost when blowdown runs too long
Typical setup: Pipe Monitors on makeup and blowdown
Find broken heads in days, not billing cycles
Irrigation leaks hide in the landscape and look normal on a monthly bill. NOWi shows a zone that never shuts off.
One garden-style community found 71,000 gallons a month in leaks across 15 buildings and 3 irrigation meters.
What it saves you
- Water from broken heads and stuck valves
- Landscape damage from overwatering
- High bills in the hottest months
Typical setup: a Meter Monitor on each irrigation meter
Catch leaks over weekends and breaks
Schools and campuses sit empty for days, exactly when a leak runs unnoticed. NOWi alerts facilities wherever they are.
Trusted by Gilbert School Systems and Montana State University.
What it saves you
- Leaks running over weekends and breaks
- Damage found only when staff return
- Budget lost to water nobody used
Typical setup: Meter Monitors on building meters
