Hospital Water Tank Cleaning & NABH Hygiene Norms in Delhi

In a hospital, stored water is not a facilities issue — it is an infection-control issue. Waterborne organisms in a healthcare setting reach immunocompromised patients, and NABH assessors treat water safety management accordingly.

What accreditation expects

• A documented water safety plan covering source, storage and distribution
• Scheduled sanitation of all storage with retained records
• Periodic microbiological testing at defined sampling points
• Defined corrective action when a result is out of specification
• Particular attention to high-risk areas — dialysis, ICU, OT, CSSD

Why hospitals need a shorter interval

Two reasons. First, patient vulnerability — organisms that a healthy adult clears without noticing cause real harm in an immunocompromised patient. Second, hospital plumbing has long, complex runs with low-flow branches where water sits, and stagnation is what lets biofilm establish.

Quarterly cleaning of all storage is the practical baseline, with high-risk-area supply lines treated on their own schedule under the infection-control committee.

How we work in a live hospital

• Scheduled around clinical load, usually staged tank by tank so supply is never fully interrupted
• Coordination with the infection-control team before and after each round
• Food-grade disinfection with documented dose and contact time
• Written report per tank with before-and-after photographs
• Sampling coordinated with the hospital’s empanelled laboratory

Documentation is the deliverable

For an accredited or accreditation-seeking facility, the report matters as much as the cleaning. Ours name each tank, record capacity, date, crew, chemicals and doses used, and carry photographs — so the file stands up in an assessment without anyone reconstructing it from memory.
