Greywater is still wastewater
Water from washing, sinks and simple cleaning can still carry food, soap, grease and contaminants. It needs a planned route, not a casual hole in the ground.
First checks
Look at what enters the water, where it can be collected, how often it needs emptying, what freezes, what smells and what local rules allow.
Publication rule
Keep greywater articles conservative. Do not present a disposal method as legal or safe without location-specific review.
