Also Caution: that’s DC’s only source of drinking water. Gorgeous photos from a beautiful weekend here in the Mid Atlantic! @dcwater

Not your typical fall foliage photos! 🍁 Two daring kayakers took the plunge over Great Falls on Sunday morning, navigating the Potomac's powerful rapids against a stunning backdrop of autumn color. Kevin Ambrose (dcstormchaser) captured the action in spectacular photos. Caution: kayaking these powerful rapids is an extreme challenge reserved for highly experienced, expert paddlers.

What's Emily been up to since her blessing? 💧 Her massive cutterhead, protective shields, and first six support sections have been lowered underground. Crews are now connecting her electrical and hydraulic systems ahead of testing and her planned December tunneling launch.

🌊 Happy #WorldRiversDay! DC Water’s Clean Rivers Project is helping reduce stormwater and sewage pollution and improve water quality in the Anacostia and Potomac rivers and Rock Creek. Here’s to protecting DC’s waterways today and for generations to come.

1/2: Collaboration is a term that gets mentioned a lot but yesterday's workshop was genuinely a first-of-its-kind event. It was the 1st time *both* drinking water & wastewater utilities came together to discuss our individual & collective DC regional water supply challenges💧

💧 What does the future of our region’s water supply look like? This week, DC Water joined @MWCOG and regional water utilities to plan ahead, explore additional drinking water sources and discuss how we can better prepare for changing needs across the region.

There she is! 👋 Soon, Emily will head underground and begin tunneling approximately 3.1 miles south toward Joint Base Anacostia-Bolling. Her sister Mary is already underground, tunneling north. #PRTEmily

While much of DC was winding down, our crews were working after dark to inspect and secure manholes along the Freedom 250 Grand Prix route. 🏎️ It’s part of months of preparation to protect our infrastructure, keep services reliable and ensure our teams are ready to respond.

Our screens catch a lot. They shouldn’t have to catch EVERYTHING. 🙄 Meet Jun Fang, DC Water’s Manager of Process Engineering, for a closer look at the bar screens at Blue Plains and why plastic, rags and other trash don’t belong in our wastewater system. 💧 #PlasticFreeJuly
