Water Management Program Design, Roles, and Documentation
The seven elements
ASHRAE 188 organizes a water management program (WMP) around a program team, water system description and flow diagrams, hazard analysis, control measures, monitoring, corrective actions, and verification/validation procedures, all tied together by documentation.
Roles
Team membership is multidisciplinary and named: facilities engineering, infection prevention, clinical leadership, the water treatment provider, a plumbing or mechanical contractor, the laboratory, and administration with budget authority. Each element needs an owner, a backup, and authority to act. Contractor and vendor responsibilities must be written into the program, not assumed.
Documents
A signed policy statement; team roster with roles and contacts; system description and diagrams; hazard analysis results; control measures with target and action limits; a monitoring schedule (parameter, location, frequency, method, responsible person); corrective action procedures with escalation; verification and validation plans; records retention; training records; a communication plan covering patients, staff, public health, and the water utility; and change-management triggers (renovation, new equipment, outage, water quality change).
Traps
A team of one; a program with no funding or authority; binders that do not reflect the actual building; missing revision dates and signatures; no defined notification path; and no update after construction or an occupancy change. Examiners also like scenarios where the program exists on paper but nobody can name who monitors, who is notified, and who signs off.
Rule of thumb
A program element does not exist until three things are true: a named owner, a written procedure, and a record that proves it happened.
