When the Water Stops (or Changes):
Hospitals don’t always plan enough for boil water alerts, construction shutdowns, or sudden water system interruptions—yet all three are guaranteed to happen at some point. What determines whether these events become routine operational challenges or serious clinical risks is how SPD water is reintroduced into the system afterward.
This is exactly what Section 13 of ANSI/AAMI ST108 addresses—and what Wendy Schultz, VERDA’s Water Quality Services Manager, focused on in a recent webinar (Episode 6: Water Quality & Unexpected Events):
Post-construction or extended shutdown (ST108 13.1)
Extended boil water alerts and steps after alerts are lifted (ST108 13.2)
Interruptions in service and controlled shutdowns (ST108 13.3)
This section of the standard is where Facilities Engineering and Sterile Processing become operationally inseparable.
ST108 13.1 — Post-Construction or Extended Shutdown: Water Does Not “Reset” on Its Own
Wendy makes a simple but critical point:
“There are methods for turning water on into new pipes. This is typically performed by Facilities and Engineering according to ST108 13.1.”
This means water restoration after construction or extended downtime is not a casual step—it is a defined procedure. Newly installed or idle piping must be treated as unknown-risk infrastructure until Facilities deliberately reintroduces flow using controlled methods.
“Just because construction is complete doesn’t mean the water is automatically safe to use again.”
For SPD, this is a key distinction. Processing cannot safely resume based on assumption—it must follow verified system recovery.
Hospital Example #1: Construction Ended — Recovery Was Assumed
At Hospital A, a Decontam expansion wrapped up after six weeks of construction. On Friday afternoon, Facilities restored water to the space. SPD returned to full production Monday morning.
What didn’t happen:
No formal post-construction water introduction process
No verification step between Facilities and SPD
No delay before final rinsing resumed
By midweek:
SPD began seeing inconsistent washer performance
Instrument spotting appeared during inspection
Loads were paused while leadership traced the issue back to the post-construction restart
Construction had ended successfully.
The water restart was treated as routine instead of procedural.
Within a week:
SPD began noticing instrument staining and spotting
Washer performance became inconsistent
Final rinse conductivity readings crept upward
A failed biological indicator appeared in a sterilizer load
The root cause?
Biofilm introduced during idle piping and construction exposure. Ambient air entered open piping during repairs—exactly the risk ST108 warns about.
The hospital response escalated quickly:
Case carts were quarantined
Emergency water sampling revealed microbial excursions
A full system disinfection was required
OR cases were delayed for two days
This wasn’t a failure of equipment.
It was a failure of process, documentation, and coordination.
ST108 13.2 — Extended Boil Water Alerts: Lifting the Alert Is Not the Same as System Recovery
Shifting the focus to boil water advisories:
“Extended boil water alerts and steps to take after alerts are lifted”
“Recommissioning after a boil: the right way to restart”
“How to verify, sanitize, and document water system recovery per ST108 13.2”
ST108 clearly separates:
Municipal clearance from
Hospital system recovery
Wendy’s message in the notes is direct:
“The boil water notice ending does not mean SPD can automatically resume use of critical water.”
Recovery must be verified and documented before clinical processing continues.
Hospital Example #2: Boil Alert Managed by the Book
At Hospital B, a regional water main break triggered a 48-hour boil water advisory.
Their response followed ST108 13.2 strictly:
SPD immediately suspended use of critical water
Facilities managed system isolation during the alert
When the advisory was lifted, SPD did not resume automatically
Facilities completed the defined recovery steps
Leadership documented verification before processing resumed
The outcome:
No instrument quarantine
No sterilization delays
No OR disruption
No regulatory exposure
Same type of municipal event.
Completely different outcome—because recovery was treated as controlled, not assumed.
What is Unmistakably Clear
From these scenarios alone—construction, boil alerts, and service interruptions—one responsibility becomes unmistakable:
Facilities Engineering controls the restart
SPD controls the clinical exposure
ST108 makes both accountable for the outcome
These are not “water problems” or “SPD problems.”
They are shared patient safety events.
Final Takeaway
ST108 Section 13 exists because:
Water systems are routinely disrupted
Recovery carries invisible risk
Restart must be procedural, verified, and documented
Turning the water back on is not just a Facilities task.
It is a clinical decision.
