June Walden.

Background

June grew up in Tempe, did a BS in electrical engineering at Arizona State (1992), and arrived in Tucson the same fall to work at the original Tucson Water electronics shop downtown. Spent twenty-eight years moving from PLCs and analog telemetry through three generations of SCADA platforms — from a Bristol Babcock OpenBSI installation in 1996 to the current ICONICS GENESIS64 system that runs the production-side controls. She retired in June 2023 with the standard 28-year pension and the explicit intention of doing nothing for a year. By Christmas she was reading Lamb's Industrial Automation in bed and missing it.

What she does

June handles every controller install on cisterns 5,000 gallons and up. She also rebuilt our default Hunter X-Core templates so they integrate the Solar Sync ET sensor properly (most off-the-shelf installs do not), and she wrote the small Adafruit IO dashboards we offer to clients with bigger arrays. She's part-time, three days a week, and entirely uninterested in expanding to four.

The other thing June does is the rain log. The published ledger of rainfall events with field notes is her project; she reconciles each event from at least three gauge sources and writes the per-event field summaries from the crew's Slack messages. She enjoys the data side as much as the controllers.

A note on dashboards

The Adafruit IO dashboards we ship for clients with cistern arrays of 5,000 gal+ are entirely June's design. They do four things, no more: show current tank level, show last 30 days of capture, show last 7 days of distribution by zone, show controller status (running, off, fault). She refuses to add weather widgets, push-notification anxiety triggers, or "smart home" integrations, and we agree with her on principle.
