When you complete main mission 19 in Pokémon Legends: Z-A, you get your promotion to Rank D. During that mission, you also visit the sewers present under the Clawitzer fountain. But when you return after completing the main quest, you’ll find the entrance to the sewers blocked. If you wish to re-enter the sewers, we have a guide ready for you.
Steps to Return to the Sewers in Pokémon Legends: Z-A

Fast travel to Café Woof in Bleu Sector 3, follow the left path past the lady with Audino, clear the purple grime, and take two lefts through the tunnel to reach the sewer entrance in Pokémon Legends: Z-A. Remember to bring a water-type or confusion attack Pokémon along with you because they will be crucial for the re-entry.
Instead of going to Bleu Sector 7, where the sewer entrance was during the main mission, you need to go to Café Woof, present in Bleu Sector 3. From there, head straight to the middle of the building. There will be a lady alongside her Audino. You don’t need to interact with the lady, but take the stairs next to her and take the first left.

You’ll encounter purple grimes there. Use your water-type or confusion attack Pokémon to clear the way for yourself. The path will lead you down some tunnels. In those tunnels, take two lefts to reach the new entrances of the sewers.
However, an NPC will be blocking your path, offering you a sidequest, The Camerupt Entrepreneur. You just need to accept this sidequest to gain access to the sewers. Without completing the side quest, you can enter the sewers via the gate present at the new location. A permanent map icon will also appear to show that you can enter the sewers any time you want.
