Hello everyone,
I own the Smart 6000 cistern. It is extended with a riser shaft. The riser shaft ranges between 39.5 and 61 cm (15.5 and 24 inches). I’m not sure how far it is extended; I would need to open it and check—that’s how it’s done, I guess.
Now our plans for the outdoor area have changed, and we would need to raise it by about 90 cm to 1 m (35 to 39 inches).
Problem A: The company Nautilus does not offer a riser shaft like that. The maximum height is the one mentioned above, which would give me a maximum of 61 cm (24 inches). If the current one is only extended to 39.5 cm (15.5 inches), then I could get 61 cm + 61 cm - 39.5 cm = 82.5 cm (33 inches), which might be workable.
Problem B: There is a filter installed somewhere in the cistern. With a riser shaft that is up to 1.60 m (5 feet 3 inches) deep—wherever you would get such a thing from—you would never be able to reach that without diving equipment.
Problem C: The manufacturer’s specifications state that the cistern can only be extended up to 77 cm (30 inches) above the standard installed lid in order not to exceed the maximum soil coverage. My ground is dry sand. I assume this weighs less than clay, loam, etc.—is that still a problem, and could it damage the cistern?
This is a classic planning mistake on my part. So what now?

We are in the final stages of floor plan design with the architect and have had the house positioned on the existing plot.
The house is planned to be built at street level – unfortunately, the plot drops about 1.5 meters (5 feet) right after the street edge and then slopes down another meter (3 feet) over approximately 30 meters (98 feet). As a result, our house including the driveway and carport is currently suspended in the air, and we’re not quite sure how to incorporate this into an attractive site design. … which makes me wonder how well the intervening time was used to avoid anything going seriously wrong :-(

HeimatBauer10 Aug 2023 15:31If the plans have changed now, I would design the cistern accordingly. It also needs a pump with a floating intake, etc. Perhaps this is a good time to consider using concrete right away.
According to the manufacturer, a 77cm (30 inches) extension is acceptable; anything beyond that is your responsibility. In the worst case, you could end up with a large hole in your yard — then you would need to install an appropriate cistern, which would otherwise be the alternative now. It is probably easier to sell it in a new condition than if it’s compressed like a damaged diving bell. No one can tell you how realistic this is — calculate for yourself and assess your own risk tolerance. Then consider whether you can resell the obvious wrong purchase, what the additional costs for the correct concept would be, and if the risk is worth it for you.
If you buy a cistern in advance and only plan later, your risk tolerance is quite limited.
