Main Pipeline Plan - Wastewater Drainage and Elevation Planning

Then it is all the more important that it has structure and makes sense. The building exit downwards is not necessary. If I see it correctly, it is supposed to be connected to the sewage shaft at the top left, 15m away, right? It makes sense to keep the pipes under the floor slab as short as possible. In conjunction with the position of the shaft, however, it would be a compromise to run it out to the left of the building. But information is missing as to whether the pipe can be run outside there at all. Downwards automatically results in the longest pipe route. Whether this is possible is determined by the connection height at the sewer. However, I also see no problem in leading the pipe directly under the floor slab upwards to the street. That would be the shortest way.

I hope you can differentiate If I may give you a tip: stick to the professional "short and concise".

I would carry it out according to the given plan and lead a flushing nozzle (Finor) to the outside at the last one (at the very top in the plan).

If drainage is carried out upwards according to the plan on the GFL, the alternative is better, as it is estimated to be 6m shorter and 6cm higher.

Then it is all the more important that it is well-founded. A building exit downwards is not necessary. If I see that correctly, the connection is supposed to be made to the sewage shaft at the top left at a distance of 15m, right?
It makes sense to keep the pipes under the floor slab as short as possible. Considering the shaft’s position, however, it would be a compromise to run left out of the building. But there is missing information whether it is even possible to run the pipe outside on that side.
Downwards naturally results in the longest pipe run. Whether that is possible is determined by the connection height at the sewer.
But I do not see any problem running the pipe directly under the floor slab upwards toward the street. That would be the shortest route.

Yes, I also have a huge respect for that.

Yes, there is an existing sewage shaft that should actually be used. Theoretically, pipes could also be run counterclockwise (through the garden).
But I don’t want to go left, but right, because that is the [GFL] strip and the neighbor behind has to run his pipes through there anyway. The strip always remains free and may not be built over, which means I will always have access to my pipes. And it is also 5-6m shorter than in the plan. For the earthworks there are synergies, or we share the costs if we both go through the [GFL].
I am just considering whether in the end it’s better to simply commission a new shaft in the [GFL]…

I would carry it out according to the prescribed plan and lead a flushing nozzle (Finor) outward at the last one (at the very top of the plan).

I do not quite understand. What does that mean?

If drainage is done on the [GFL] toward the top of the plan, the alternative is better since it is an estimated 6m shorter and 6cm higher.

That’s how I see it so far as well. But the site manager argues here with longer pipe runs under the slab. I can’t quite understand that, but maybe I’m missing something?

At first glance, the pipe lengths are the same, I suspect he wants to have all the pipes (water, sewage, electricity, heating, etc.) in one pit. We placed this pit directly next to the GFL and also connected it from there. Now we also have a flushing connection for sewage there. Every autumn, water runs from the cistern for one hour; from there it is 60m to the sewage channel. I only help Berlin to clear the pipes from leaves.
