ᐅ Pressure drainage system (for wastewater only)

Hello everyone,

We are building on a slope and have received a proposal for pressure drainage.
Has anyone had experience with this? Normally, water flows downhill.
The drainage system involves a small pump that would pump the wastewater about 40 meters (130 feet) uphill, overcoming a height difference of approximately 6 meters (20 feet), which sounds promising.
We could save around 10,000€ by using this.

I would appreciate your opinions.

Good luck

Save 10,000 € compared to what?
Sending the wastewater downhill once around the equator?

Always consider operating and maintenance costs when choosing pumps.

A bit more in detail. The house will be built into a slope. A lift station is planned to raise the water to yard level. However, from there it is still some distance to the street and the terrain slopes upward. An underground drain with a gradient is planned toward the street, and at the end, the water is raised again to street level using a pump. To avoid having two pumps and extensive deep excavation work, the wastewater technician suggested the Jung pump Multicut 20/2 M. This pump can transport the water through a high-pressure line directly into the sewer. This would make the drainage system significantly more cost-effective. My question is whether anyone has any experience with this.

Good luck

I installed exactly this type of pump as a twin system because I need to pump both wastewater and rainwater. There is about a 1-meter (3 feet) height difference with a 15-meter (50 feet) pressure pipe.

It’s only been running since January, but so far I’m very satisfied. The pumps mostly sit idle. The total runtime of the pumps is just under 5 hours, which translates to around $6 in electricity costs.

I haven’t received any quotes for annual maintenance yet.

Thanks the_M. At the moment, it looks like we will implement it that way.

How is the smell? Is the shaft airtight?
