ᐅ Is it possible to install drain pipes and sewer pipes side by side?

netzplanHello everyone,
On one side of the house, I have the issue that a 100mm (4 inches) KG2000 pipe (wastewater) and a 100mm (4 inches) drainage pipe need to be routed in a tight corridor of about 50cm (20 inches) at roughly the same level towards the sewage shaft. Unfortunately, I can no longer adjust the heights as the slope of 1-2% already leaves very little room.
How would you approach the installation in such a case? The KG pipe should be embedded in sand (e.g., red cable sand), while the drainage pipe is supposed to be bedded in gravel (16-22mm). If both are placed side by side like this, there is a high risk that the sand will be washed away. According to my builder, the KG pipe can also be surrounded by gravel or similarly installed within the filter layer. Even 5-12mm crushed stone is reportedly better (which I don’t quite understand).
Do you have any recommendations for installing the drainage and KG pipe close to each other? Approximately 50-60cm (20-24 inches) above these, there will be more KG pipes (e.g., for the garage and rainwater). For this, the lower area would have to be well compacted to prevent settlement of the KG pipe above, or perhaps an additional intermediate layer could be used to avoid the sand bedding being washed out.
Best regards
