Drainage Systems

There are apparently a few main types of fittings. One is the Access Chamber (small holes for inspection) and Inspection Chambers (larger chambers which have space for maintenance equipment and crew to go into).

As for drains, apparently there are two systems - foul water sources (kitchen, toilet, bath, industrial) and surface water sources (rainwater, road).
