The slope is one-quarter inch per running foot of drain pipe. It was arrived at through trial and error, over time. It was observed that if the decline in the pipe was less than this, particulate matter would be left behind by the slow-flowing water and the pipe would clog up. However, if the decline was more than this, the water would run away too quickly and leave the particulate matter behind, and the pipe would clog up.
