Aurora has begun using smart water meters and automated data analysis to identify residents who irrigate outdoors on days when watering is restricted, city water staff say. The move is part of a broader push to stretch a diminishing municipal supply during an ongoing drought.
How the system works
Smart meters installed across the city transmit consumption readings every 15 minutes by cellular signal. The water conservation team analyses roughly 2.2 million data points each day to look for patterns consistent with irrigation, such as repeated early-morning spikes that suggest timed sprinklers.
- Data is processed by scripts that flag likely outdoor-watering events.
- Staff manually review flagged cases before issuing warnings or fines.
- Residents who dispute a finding can contest it; staff review the evidence with customers.
Tim York, who leads the city’s water conservation work, demonstrated how the system zeroes in on repeat patterns — for example, spikes at 4 a.m. on the same days of the week — and said most flagged households agree with the data when staff discuss it.
“We look at about 2.2 million data points for each individual day … and we built some scripts that run against that data on a weekly basis to say ‘was somebody irrigating when they’re not supposed to be?’”
Why the program was introduced
The city says reservoir levels are strained; supply is currently around half full, and the usual replenishment from snowmelt has not materialized. To conserve water, Aurora has mandatory outdoor watering limits that allow irrigation only two days per week.
Officials report that since the smart-meter monitoring began, outdoor water use has dropped by about 20 per cent, while warnings for overwatering have more than doubled. The city emphasizes that initial outreach is focused on compliance and conservation rather than punishment.
| Metric | Reported value |
|---|---|
| Data points analysed per day | 2.2 million |
| Meter reporting frequency | Every 15 minutes |
| Reduction in outdoor use | ~20% |
| Current reservoir level (reported) | ~50% |
Local impact and next steps
For residents, the change means two practical effects: increased monitoring of irrigation patterns, and a higher chance of receiving a warning if they water on non‑permitted days. City staff say human review remains part of the process to reduce false positives and to give homeowners a chance to explain anomalies.
Officials say the program aims to preserve municipal supply without resorting to more draconian restrictions. With outdoor watering down and more warnings issued, the city hopes to protect summer supply levels while keeping enforcement targeted and transparent.
