You’ve Asked and Thornton is Delivering: Daily Usage Data in the WaterSmart Portal

Customers frequently ask if we can give them daily water usage data, especially when they are investigating a high-water bill. Thornton Water is excited to announce the launch of Advanced Metering Infrastructure (AMI) data. The new feature in WaterSmart will show daily water use patterns to help customers manage usage and detect leaks more quickly. This data is available to most residential water customers now and will be available to all residential customers by the end of the year. As it becomes available in each area, customers will be able to access it in the portal.

Understanding AMI Daily Data vs. Monthly Billing Data

Daily Data

These are detailed meter readings automatically taken every day, or even more frequently. They help you:

  • Track water usage in near real-time.
  • Spot leaks quickly before they become expensive.
  • Understand usage patterns, like outdoor watering or peak times.
  • You may see missing data due to network interference; missing data will not affect your bill.

Monthly Billing Data

These are the official meter readings we use to calculate your monthly bill.

  • Taken once per monthly billing cycle.
  • Based on total water used over the billing period.
  • Follows the normal billing schedule.

Why both?

Daily data provides insights and tools for managing your water use, while billing data ensures accurate and consistent charges on your account.

You can access your billing and daily data through the WaterSmart portal. This user-friendly platform allows you to monitor your water use in near real-time, set up leak alerts, and evaluate how changing your water habits can affect your usage and your bill. For more information on AMI, contact water@thorntonwater.com or 720-977-6600.
