The kit is the set of components that turns a master-metered property into per-unit billing.

## What is in a water submetering kit?
A water submetering kit is the bundle of components needed to measure and bill each unit's water. The main parts are the water meters, one installed on the supply line feeding each unit, plus wireless repeaters placed around the property to relay readings, and a gateway that collects those reads and sends them on. With wireless meters, the kit also supports daily monitoring and alerts, so leaks and unusual usage surface fast instead of showing up on a surprise bill. NES provides submetering kits for condominiums, mobile home parks, and apartment communities, and once the equipment is installed we handle billing your residents for what they use. The equipment is nonproprietary, so you own it and it carries a warranty. We focus on properties with 80 or more units, and most owners see payback in 12 to 18 months.

## The components
- Water meters, one per unit, on each unit's supply line.
- Wireless repeaters placed around the property to relay reads.
- A gateway that collects the reads and forwards them for billing.
- Daily monitoring and alerts when wireless meters are used.

## What the kit lets you do
Once the kit is installed, you can see which units use the most water, take steps to bring consumption down, and bill each resident for their own use. NES handles that billing for you. Daily reads also mean a hidden leak shows up as unusual usage within a day, not at the end of a billing cycle.

## Questions
**Do I need repeaters and a gateway, or just meters?**
A full kit includes meters plus the repeaters and gateway that move readings across the property, which is what makes daily wireless reads possible.

**Who handles billing after the kit is installed?**
NES does. Once the equipment is in, we bill your residents for the water they use.
