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.

Do you use a crowbar for that or another special tool?I use a hammer, hooking the hammerhead and lifting it by the handleHello,
I also use a pry bar like that and check the system every couple of months. Our filter looks like this.
I attached a kind of fork to the end of a long rod. With this, I pull out the filter once in spring and once in autumn/winter and rinse it clean. The water from the cistern is crystal clear. All downpipes in our system have two filters installed: one at the top in the gutter and one near the inlet to the pipes. It works very well. I clean them twice a year as well.
