Rechargeable batteries DO NOT🚫belong in the garbage. Especially lithium-ion batteries can spark when damaged, causing fires🔥in garbage trucks, at recycling facilities, and at landfills.
Please bring them to one of MMSD’s Home HazMat Collection Centers, open all year. Milwaukee County residents ONLY. No businesses.

According to Wisconsin Department of Natural Resources, alkaline batteries are no longer considered hazardous and can go in the garbage. For Home HazMat locations, hours, and a list of items you can bring, visit đź”— https://www.mmsd.com/what-you-can-do/home-haz-mat-collection

đź’§ See the light. Know the signal.

Ever wondered what those WaterMarkers around Milwaukee are all about? Watch this video to learn what they mean and how you can help when heavy rain is on the way.

When a WaterMarker flashes, it’s time to use less water. When we all do our part, we can help reduce the risk of sewer overflows and basement backups.

During heavy rain, rainwater and groundwater—often called clear water—can enter and overwhelm your sanitary lateral, the pipe that carries wastewater from your home to the sewer. When this happens, sewage and water can back up into your basement.

Common sources of clear water include:
🌧️ Downspouts connected to the sewer system
🏠 Foundation drains
🌳 Defects in your sanitary lateral, including damage from tree roots

Reducing the amount of clear water entering the sanitary sewer system can help lower the risk of basement backups.

Odor Alert: Bay View Area

Work is currently underway at the South Shore Water Reclamation Facility, which has reduced the plant’s available capacity.

With the recent rain, we are currently diverting wastewater to the Deep Tunnel based on inflow and conditions at the South Shore facility. The diversion can contribute to odor conditions in the Bay View area. The odor-control fan and activated carbon system are operating, and MMSD staff are monitoring conditions.

📢 If you notice sewer odors in your home or neighborhood, please let us know here: https://www.mmsd.com/about-us/contact-us/sewer-odor
