Are you planning to visit the nation's capital this summer to celebrate #America250?
As you prepare for your trip, remember that Washington, D.C., is a #NoDroneZone, so leave your drone at home.
If you see unauthorized drone activity in the city, call 1-800-CALL-FBI (1-800-225-5324) or tell law enforcement officers stationed near you.

Your AC needs good air flow to operate effectively & efficiently.❄️🌬️ With temperatures creeping up, now is a great time to clear the area around your unit of any vegetation or debris. When your system doesn't have to work as hard, it creates fewer #emissions!

Save water today. A regional #DroughtWatch means supplies are OK, but voluntary conservation now helps protect our rivers and avoid tougher steps later. Start with one tip: full loads only for your laundry and your dishwasher. #WiseWaterDMV #DroughtWatch

Due to ongoing dry weather, the Metropolitan Washington Council of Governments has declared a Regional Drought Watch, covering nearly six million residents across DC, Northern VA, and suburban MD, including Fairfax Water customers. While our local water supplies remain stable, voluntary conservation now helps safeguard the system in case dry conditions continue.
Simple ways you can save water:
-Reduce shower length
-Turn off water while brushing teeth, shaving, etc.
-Fix leaks, especially faucets and toilets
-Only run full loads of laundry or dishes
-Sweep, don’t hose, sidewalks and driveways
-Avoid washing your car, or instead use a commercial water-recycling car wash

Home AC accounts for ~6% of electricity produced in the US. To reduce #energy use & improve #AirQuality, use your windows to your advantage this spring!
Open windows to cool off on mild days & draw curtains on sunny sides of your home when temps rise.🪟🍃☀️
