By installing a cistern with an emergency overflow connected to the sewage system, we can reduce the rainwater charge to 10% of the usual estimated amount. If the overflow is directed to infiltration, it can even be reduced to 0%. This would save us about €250-300 per year, which is why we are interested in installing a cistern.
Unfortunately, there are many different suppliers, options, and prices available here, so my question is: What did you pay attention to when purchasing, what can you recommend or not recommend, and what were your prices?
Our key requirements:
- We would like a capacity of around 6000-7000 liters (1600-1850 gallons), as we have a large garden with many beds.
- A convenient withdrawal point is essential for us; preferably a pump with good pressure and a type of faucet that can be mounted at waist height.
- So far, I am leaning toward a concrete cistern.

Hello Nixwill2
Use filter number 1. It is more than sufficient.
I have the same one, a 10m³ (13yd³) concrete cistern.
The water is crystal clear. So far, in 14 years, I have only had to clean the filter thoroughly once.
This or next year, I will completely drain the cistern for the first time to check if the bottom is muddy.

Hello Steven,
thank you for your reply.
Where exactly is the filter located in option 1? Outside? Our cistern will be placed right in the middle of the driveway and will basically be paved over (of course, not the lid 🙂). I guess there won’t be access to it from outside without adding something extra.

Your version 1 at the top is probably completely without a filter and relies on coarse material being caught already in the gutter?
At my parents’ cistern, I don’t think there is a filter installed either. Every few years it is flushed out with a pressure washer when there’s only a small amount of water in summer, and then the sludge is removed with buckets.
