Term Definition
Impact properties

Multi-family properties that are using a billing method where residents receive a regular bill determined by a system such as submetering, RUBS, or hot water hybrid, etc.

In-rent properties

Multi-family properties that do not separately bill residents for water and/or wastewater, rather these costs are recovered as part of the monthly rent. In properties where utilities are billed in rent, lower occupancy units effectively subsidize the water consumption of the units with more occupants.

Individual metering

The installation of meters for each individual dwelling unit as well as separate common are metering with the local water utility providing customer read, bill and collect services.


The International Protection Rating (IP) classifies the degrees of protection provided against the intrusion of solid objects, dust, accidental contact, and water in electrical enclosures. The numeral 6 in IP-68 stands for protection against water from powerful jets from any direction; the numeral 8 stands for protection against immersion in over 1 meter (3 feet) of water. AMR transmitters used in manufactured housing, marinas, and RV parks must be IP-68 compliant.
