Project Summary

As California and much of the West descend further into drought, real-time high quality data is essential to understanding current and future conditions. Flume is a device that straps around residential water meters, that collects water use every 5 seconds and shares high definition water data with people and the communities they live in. During this presentation Flume will share how they collect and analyze residential water demand data, end-use disaggregation, and more. Specifically, they will explore California and Western specific data on:

  • Indoor gallons per capita per day (GPCD) and data Flume provides to utilities for AB 1668 / SB 606 water conservation measures
  • Impacts of drought and drought restrictions on outdoor water use
  • Water use trends for California’s biggest metro areas
