The cost of greywater systems varies on how simple or complex it is to alter the plumbing, how large the yard is, and who is doing the installation. For simple systems much of the work is digging; digging mulch basins and digging trenches to bury pipe. If you’re on a limited budget labor costs can be reduced if you are willing to do much of the digging yourself, or find some eager friends or family who want to support greywater installations (and learn in the process).
These are rough average costs, exact costs will vary depending on the size and complexity of your site.
