Costs for lifting system pump sump

Hello,

unfortunately, we have to plan a lifting system for black water (slope house). Currently, a pump sump is planned in the technical room with 100x100x70cm. What costs can I expect for this? Our general contractor offered me this pump sump ready-made in the floor slab (without pump) for almost €2800. Seems very expensive to me - does anyone have experience with this?

Hello,

we also installed a pump sump in the technical room. The costs were around €1500 for 100x100x80cm including delivery. The excavation contractor then installed and connected it. I can no longer specify the exact costs for this in detail.

Regards
