body
DEPARTMENT: Water Utilities
SUBMITTED BY: Darrell Blenniss, Director of Water Utilities
BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
Staff reviewed updated data from four primary dashboards to prepare for the April meeting:
? SAIDI (System Average Interruption Duration Index): 12-Month period ending February 2026.
? Water Consumption Report: Historical and YTD usage through February 2026.
? Distribution Leaks: 2026 YTD snapshot.
? Effluent Report: Springbrook Treatment Plant 2026 YTD performance.
(Note: The Non-Revenue Water Loss metric is evaluated on an annual basis and has been removed from this interim update).
DISCUSSION:
1. System Reliability (SAIDI) Stabilization The previous report noted a significant data anomaly that temporarily spiked the 12-month average SAIDI to over 9.5 minutes. Following quality control reviews and the progression of the rolling 12-month window, this metric has stabilized.
? Current Status: The 12-month average SAIDI currently stands at 5.77 minutes per customer, which is a moderate 8.35% increase compared to February 2025 (5.32 minutes).
? Interruption Profile: While the total number of system interruptions dropped significantly year-over-year (31 YTD vs. 48 last year, a 35.4% decrease), the severity of those incidents increased. The average duration of an interruption rose to 222.1 minutes (+15.4%), and the average number of customers affected per incident grew to 14.3 (+30.4%).
2. Water Consumption Trends * YTD Observation: Total water consumption through February 2026 was 679 Million Gallons (MG). This represents a slight increase compared to the same period in both 2024 and 2025 (which both recorded 665 MG).
? System Capacity: Despite the slight uptick in early-year usage, the daily average for 2026 currently sits at 11.51 MG. This remains well below our Lake Michigan allocation (21.68 MG...
