ᐅ Suitable Slope for Wastewater Drainage

Questioner
Hello everyone,

we have finally purchased a rural plot in North Rhine-Westphalia. A small river runs behind our property. We would like to discharge the wastewater directly from the house into the river to save on sewage costs. The plot is quite large, about 3,700sqm (40,000 sq ft), so the distance between the house and the river is correspondingly long.
How steep does the slope need to be for the water to flow properly while also carrying enough solid material (e.g., sewage, etc.) along with it?

Best regards

Seems even more difficult than in Germany...
Are the Indians aware of this?

The Ganges supplies water to about 40 percent of the Indian population. According to studies, it is one of the most polluted rivers in the world. "In Varanasi alone, wastewater is discharged untreated into the river at 22 different locations," explains Udai Kant Chaudhary, director of the Institute for Ganga Management.

Definitely not. And you can’t just overhaul the existing structure like that. But it’s an interesting discussion here.

The original poster isn’t really interested in this anyway. Wasn’t there a thread yesterday saying, “I want to remove all the trees because the pollen bothers me and the birds are too loud there. By the way, I also want to create a concrete race track in the garden for my little one and for wheelies, without any trees”?

That can only be trolling.
