The most ancient system yet discovered About the drains, Mackay noted
certainly the most complete ancient system as yet discovered. * Every house was
connected to the street drains. The main channels were made of bricks sein
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
sump or cesspit into which solid matter settled while wastewater flowed out into
the street drains. Very long drainage channels were provided at intervals with
sumps for cleaning. It is a wonder of archaeology that little heaps of material,
mostly sand have frequently been found lying alongside drainage channels, which
shows that the debris was not always carted away when the drain was cleared
