Joint Base Andrews prepares for WSSC-projected water restrictions, outages Published July 16, 2013 11th Wing Public Affairs JOINT BASE ANDREWS, Md. -- Joint Base Andrews is preparing for the WSSC-projected water restrictions and outages on base. More information will be posted here as soon as it becomes available. Base residents should start following these water storage tips from the WSSC: Store 1 to 2 gallons of safe water per person per day. "Safe" is tap water in clean containers or store-bought bottled water. Store 1 to 2 gallons of purchased distilled water for any individuals with chronic health problems, including weakened immune systems. Store tap water in airtight, clean, food-grade plastic containers. Do not store drinking water in glass or used milk containers. Don't forget to store water for your pets to drink. You can use the water in your hot-water tank and ice cubes. Water stored in a bathtub can be used to flush toilets. Here are the guidelines for what to do when water restrictions are put in place this afternoon Stop using water outside. This includes filling pools, watering gardens or grass and washing cars. Take shorter showers and turn off faucets after washing hands or while brushing teeth. Don't flush after every use. Postpone using washing machines and dishwashers.
