Below are two case studies from customers with lowrise, value-add apartments based around the Bay Area.
We deployed water monitors that actively monitored the building water usage and alerts the owners whenever a leak was detected.
Customer 1
Multifamily buildings with between 24 and 88 units per building. Most buildings only required one water monitor, some required 2.
24 Buildings:
3 buildings had leaks over $1000/month
8 buildings had leaks between $100-$1000/month
2 buildings had leaks less than $100/month leaks
11 building with no leaks.
Total leaks: 345,000 gallons/month or $11,040/month
ROI < 2 months
Customer 2
Multifamily building with between 9 and 20 units (generally smaller than customer 1).
27 Buildings:
2 buildings had leaks over $1000/month leaks
5 buildings had leaks between $100-$1000/month
10 with no leaks
Total Leaks: 159,000 gallons/month or $5,100/month
ROI < 2 months
Assumptions
$0.032/gallon cost of water + sewer in San Francisco.
