Challenge
Running toilets were wasting thousands of gallons a day, and no one could see it
Beach Lane Management had two older Manhattan rental buildings using far more water than expected.
The issue was not obvious. There was no flood, no tenant complaint, and no easy way to know which toilets were running. Water was simply flowing all day, every day, then showing up later as a higher bill.
Across 35 units, checking every toilet manually was not realistic. Beach Lane needed a way to find the waste at the source.
Solution
Runwise showed exactly where the water was going
Beach Lane installed Runwise Smart Toilet Monitoring across 421 and 447 West 43rd Street, with 29 sensors monitoring toilet activity by unit.
Instead of waiting for a bill or relying on manual inspections, the team could now see which toilets were running and fix them quickly.
The impact was immediate.
447 West 43rd reduced daily water use by 61%.
421 West 43rd reduced daily water use by 31%.
Together, the two buildings cut total water use by 45%.
Results
$23,216 in annual savings from water waste that used to be invisible
Runwise helped Beach Lane reduce daily water use by 3,974 gallons across the two buildings.
That equals about $69.54 saved every day.
In the first six months, Beach Lane saved $10,837. At the current run rate, the two properties are on pace to save $23,216 per year.
More importantly, Beach Lane now knows when a toilet starts running, not months later when the bill arrives, but right away.
That means less waste, faster fixes, and savings that do not disappear after one repair.
