High water bills in Chicago: metered vs. unmetered homes
Updated · Editorial team; not yet technically reviewed
Short answer
Many Chicago single-family homes and two-flats still pay a flat, unmetered water bill. Through MeterSave, owners current on their bills can get a meter installed for free, with a seven-year guarantee that bills won't exceed what they'd have paid unmetered; the city reported average savings of 30% for single-family homes and 43% for two-flats. On a metered home, a jump in the bill usually means a leak.

What's different in Chicago
MeterSave encourages owners of unmetered single-family homes and two-flats to volunteer for a water meter, installed free of charge, if they're current on their water bills. [1]
Participants get a seven-year guarantee that bills won't exceed what they'd have paid unmetered, as long as they stay current; the guarantee doesn't transfer to a new owner. [1]
The city reported MeterSave customers saving an average of 30% on single-family homes and 43% on two-flats. [1]
