What a water safety group does, who should be in it, and when it is required.
A Water Safety Group (WSG) is a multidisciplinary group that oversees the management of water safety risks in a healthcare setting. NHS guidance (Health Technical Memorandum 04-01) requires WSGs in NHS premises. For care homes, a formal WSG is not mandated by regulation, but the principle -- that water safety is governed by a defined group with clear responsibilities -- is good practice.
For most care homes, a formal WSG is replaced by a water safety plan that assigns specific responsibilities to named individuals: the responsible person (RP), the competent person (typically the contractor), and the monitoring team (typically housekeeping or maintenance staff). Regular documented review of water safety performance -- at least quarterly -- is the equivalent of WSG meetings.
Larger care providers operating multiple homes, or providers with complex water systems including cooling towers or hydrotherapy pools, should consider establishing a formal WSG with representation from facilities management, infection prevention, clinical leads and an external Legionella consultant.
CareHomeDesk gives you compliance checklists, maintenance logs, and contractor management tools built around exactly this kind of knowledge.
