Chicago Water Bill Massive Increase

[Blake Alan Quarrie]

Has anyone else noticed a significant increase in their Chicago water bill recently? Since acquiring a four-unit property on the Northwest side, my bi-monthly bill has typically been around $500. However, after participating in the City's lead water replacement program, I was informed that I had been underbilled. Following the installation of a new water meter, I received a true-up for the previous underbilling.

Since the meter replacement, my water usage has increased by approximately 20%, and I am now receiving monthly bills instead of the previous bi-monthly statements. As a result, my bill has effectively risen from $500 bi-monthly to $700 monthly since the pipe replacement. I've had my GC run through the property and he did not discover any leaks, so I'm purely confused why I'm seeing this massive increase.
