उत्तर

Water coming out of laundry

Explanation:

Water discharged during daily chores-like washing clothes, flushing toilets, washing dishes, bathing etc., becomes dirty. This dirty water is called wastewater. Water trickling from a damaged tap, water coming out of a shower and water flowing in a river are not dirty and hence it is not wastewater.
