Any other alternative to toilet chambers?

I am one of the people that hate the toilet chambers, apart from the protrusion which sometimes may not be totally preventable, thus creating an eyesore in the open compound, I am exploring ways of getting the mechanics of waste flow both smooth and durable. In most homes, plumbers always end up passing their pipes through chambers made with blocks, but we are now building some connections made of plastic pipes and tees, topped with a hole to serve as a manhole where any blockage could be serviced. What do you think about this?
