Question

The liquid waste from kitchens and baths of residences is known as:

• A. sullage
• B. refuse
• C. storm water
• D. domestic sewage

Answer 1

Answer: (A)

sullage

Sullage is all wastewater generated in households or office buildings from streams without fecal contamination, i.e. all streams except for the wastewater from toilets. Sources of sullage include, e.g. sinks, showers, baths, clothes washing machines or dish washers. As sullage contains fewer pathogens than domestic wastewater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses.
