Also people who leave their "grey water" open (small trickle to avoid detection) - people can be terrible - it's why we have zoning laws and building codes.
That depends what the water was used for before it became grey water. If it was taking a shower or washing dishes with environmentally-friendly soap, then big whoop.
Did you know that in the UK narrowboaters on the canals just dump their grey water into the canal? The canal system in the UK is huge, and their are tens of thousands of people who live on narrowboats year round. Narrowboats are boats narrow enough (5'10") and short enough (max 52' or 72' long) that they can fit through all the locks and bridges.
