Who is the you in this instance? The typical person in this time period lived in a small rural village, their water would have been fetched from a well, stream, or other source by themself or another family member. If you are dealing with a professional cook then it is someone who was employed by another person/organization as an employee, in which case trying to cut costs like this would be pretty easy to find out.
