Read the following passage and answer the following questions: About the drains, Mackay noted: 'It is certainly the most complete ancient system as yet discovered.' Every house was connected to the street drains. The main channels were made of bricks set in mortar and were covered with loose bricks that could be removed for cleaning. In some cases, limestone was used for the covers. House drains first emptied into a sump or cesspit into which solid matter settled while waste water flowed out into the street drains.
