Detailed walkthrough
Meet Supervisor White at Graygarden and talk to her to initiate the quest. Alternatively, one can receive this quest by speaking to Preston Garvey, or by listening to Radio Freedom, and it will point the player towards Supervisor White.
Head across the river to the Weston water treatment plant. The outside of the plant is guarded by super mutants, including a super mutant suicider, super mutant skirmisher, and hounds, and is often the target of a Brotherhood Vertibird raid so be prepared. Kill all super mutants guarding the plant.
Enter the plant via the main doors, and go down to basement via the elevator. This area is inhabited by mirelurks and ten machine gun turrets, however the turrets can be switched off from a single terminal in a room not far from the entrance to the main area. It is perhaps worth noting that every enemy inside the building is weak to energy weapons, so your multicrank laser musket or the like will come in quite handy.
There are five circuit breakers located throughout the facility and four auxiliary pumps that will lower the water level. The main pump will restore water to Graygarden.
After draining the facility, report back to Supervisor White. As a reward the player will be able to use Graygarden as a permanent settlement.
