Backdrop manholes connect pipes of differing invert levels and allow for the pipe at a higher level to connect to the lower level pipe with minimum fall. typically, backdrop manholes are used where the elevation difference is larger than 600 mm. backdrop manholes are constructed in two ways, depending on the required sizing of the pipe. And i think you'd need more than 2 backdrops. also consider that the access pipe (top of backdrop pipe) needs to be subject to minium cover, so if that is say 300mm, plus pipe dia, a 1200mm deep chamber hardly gets you 800mm of drop. not sure if it's good practice but i didn't see a max gradient in the regs, so two chambers (need a chamber at.
