Sub-metering water on mobile home park
I've recently purchased a 17 unit senior mobile home park. My operating expenses are mainly water sewer garbage. I'd like to extend the cost of the water to the lot renters by submetering each unit and sending them a bill (or having a third party do it) I was wondering, who has done this, how much I'm looking at spending, are permits needed, where can I go about getting the best deal on hardware (should I use a wireless meter which gathers data 4 times a day that I can review from home?), etc. I've completed a few google searches and a few searches on here to come up with very little helpful information. I'd like some feedback from those who have done it. The process does not seem hard, but better to know what not to do before jumping in head first :).
Thanks,
Jason
