Water Submeter -- Require Tenant to Maintain Internet Service?

[Mike M.]

Recently purchased a duplex that has separate gas/electric meters for each unit, but only a single water meter serving both units.  Having faced this situation before, my initial plan was to install a second meter in the basement and simply split off the plumbing.  However, the water company now requires that, first, a new meter pit be installed outside of the a home, a new second service line be run underground to the basement, etc.  Without getting into all of the details, it's an expensive proposition for a small duplex.

Although seemingly better suited for large properties, I looked into a submetering system as an alternative.  The $1,000 estimate for the equipment isn't unreasonable, but my concern is that this system requires internet/cellular service to transmit data to the provider.  Again, keeping in mind that this is a small duplex, as the landlord I'd rather not pay an extra $40 a month for standalone internet/cellular service.

Which leads me to my question -- insofar as the submetering system could function through a tenant's cable internet service, is there any legal prohibition on including language in a lease to require that a tenant maintain such internet service for the stated purpose of monthly water readings?  I understand that there is a federal law/regulation prohibiting landlords from favoring cable providers or dish providers.  Not aware of anything similar law/regulation concerning internet service.

Any insights would be appreciated.
