FLUME Water Monitoring System Rebate Program
A New Way to See Your Water
Rainboiw Water is the first water provider in California to partner with Flume to offer an exclusive discount on Flume, an intelligent water monitoring device. Flume is a water efficiency incentive program that allows customers to access minute-by-minute water usage data.

Homeowners are largely in the dark about their water usage. A monthly bill provides little detail, leaving the vast majority of homeowners to wonder exactly how much water they’re using and when. Flume changes that. Flume’s Smart Home Water Monitor and app provide homeowners with detailed, real-time insights into their water usage.
The device attaches directly to a water meter with a self-installation video tutorial and does not require a plumber to install. Flume users have access to their water usage down to the minute and provides a free mobile app to understand, manage, and conserve water. The app features budget and usage alerts to instantly notify users of excess water use.
Flume’s upgraded app experience, brings users a whole new level of detail and control to allow users to view water usage based on: individual appliance, compare their hourly, weekly, and monthly data. The app allows to customize usage alerts and budgets to best fit the customer needs.
For a limited time only, Rainbow Water customers can order a Flume 2 device with an instant rebate for total price of $49 (one per household). Act soon, a limited number of devices are available on a first-come, first-serve basis. To purchase please go to flumewater.com/rainbow.
You will be required to verify your eligibility for the program by entering your account number upon signing up.
