Milwaukee’s Deep Tunnel was nearly full this weekend. On Sunday morning, @tmj4news noted that the Deep Tunnel reached 98% capacity - holding 422 million gallons of water out of a max 432 million gallons. When heavy rain hits, our water reclamation facilities can only treat to much wastewater each day. The Deep Tunnel acts like a giant underground storage system, holding extra water until it can be cleaned. 💧 Huge thanks to @mmsd_mke _ #discoveryworld #deeptunnel #mmsd #engineering | Discovery W
