Looking for anyone who has used water submetering companies

[Matt Le]

I am the president of a HOA in a 6-unit condo building looking for a solution. Louisville MSD just increased rates 7% again and this year we are averaging $700/month between water+sewer bill which has basically bankrupt the association as all prior years were budgeted for half of this. Somebody, likely a long term tenant in the building, is using excessive water or won't fix their toilet flappers. Cheapest bill this year at $350, most expensive at $1200. I own 2 of the units for STR that I kept empty last service period just to get a gauge on things and the 4 other units still managed to use a combined 43,000 gallons which makes a $860 bill total that is split between Louisville Water@$321 and Sewer@$539. I know somebody will read this in 10 years and probably thinks this is now cheap. Lol

The two big companies I found on Google are ThinkUtilityService & GuardianWP. I haven't contacted either of them for pricing yet, but if anyone can share their own experience from installing sub-meters it would be helpful.. especially if there are any locals. Each unit in teh building has their own master water shutoff valve, so I can't imagine it will be that difficult to get some hardware + automated billing system through someone. I would like to be hands off as much as possible.

First post on here, so go easy on me please :P
