Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: Drop shaft manholes are usually used in steep slope urban areas in order to reduce the slope of outlet pipes when one or more of the inlet pipes have an invert elevation significantly higher than that of the outlet pipe. Usually the invert elevation of the inlet pipe is designed to be equal to the invert elevation of the manhole but in case of using drop manhole the inlet pipe invert elevation is set to be significantly higher than that of the manhole. Despite the wide usage of drop manholes structures there are no systematical studies that restrict the height of the drop manholes except for the concern of excessive aeration and corrosion in the drainage system as this may lead to poor hydraulic conditions
