Sewage System
The sewage system in the world of Gangelboba is very simple, first there is no artificial sewage system - it was all made naturally by the Ilialopops (see reference in the creatures and religions tab) who dug the tunnels underneath the city that linked every single house to the tunnels. All waste that is dropped into the tunnels is eaten by the Ilialopops and when the Ilialopops die they sink into the ground under them. When the Ilialopops population grows too large they are flushed out over the cliff to the death.
Transport System
Transportation vehicles are uncommon since they are expensive and unnecessary as everyone can just warp everywhere they feel with their own warping device. The warping device is simple and useful and comes free with their citizenship. If however a person feels the need to own a vehicle then they either buy a hover car or simple electric bikes. There are however roads for walking on and driving if need be.
