A multistage greywater treatment system including at least one separation stage, at least one solid removal stage, and at least one disinfection stage. The at least one separation stage is configured to separate water from one or more water draining device into at least three outputs including a first intermediate greywater. The at least one solid removal stage is configured to receive the first intermediate greywater and dissolve solids from the first intermediate greywater to output a second intermediate greywater. The at least one disinfection stage is configured to receive the second intermediate greywater. The resultant greywater may be provided to at least one recycled water consuming device after passing through the at least one separation stage, at least one solid removal stage, and the at least one disinfection stage.
