The facility must:

§483.70(h)(1) Establish procedures to ensure that water is available to essential areas when there is a loss of normal water supply;

Interpretive Guidelines: §483.70(h)(1)
The facility should have a written protocol which defines the source of water, provisions for storing the water, both potable and non-potable, a method for distributing water, and a method for estimating the volume of water required.

Dave’s Memo: Make sure your “Water Outage Policy” includes these elements:
1. Who is supplying the water?
2. Where will you store both potable and non-potable water?
3. Who and how will the water be distributed?
4. What quantity of water is needed for both your residents and your staff?

Potable water is considered safe drinking water. Non-potable water is water that is not of drinking water quality, but which may still be used for many other purposes, depending on its quality.
