Hi,
we want to order a cistern (about 5000 liters (1320 gallons)) online, have it delivered to us, and then have it installed. It should be a concrete cistern. Since many of you have probably already considered this and gained some experience, I wanted to ask if you could share any recommendations. Unfortunately, I could not find any reviews of manufacturers. I want to avoid ordering from the first cistern manufacturer that appears on Google and then receiving poor quality.

We direct all the water from the roofs, terraces, and so on into the cistern. We also have a well that is recirculated.

The garden requires a lot of water. Fortunately, we receive sufficient rainfall, but during dry periods, using fresh water for irrigation has sometimes been prohibited. A cistern like this is very helpful. Lawns need about 15 liters per square meter per week (0.5 gallons per square foot per week). With nearly 1000 m² (10,764 ft²), that amounts to around 60 m³ (21,190 gallons) per month. In addition, there are hedges, trees, and flowerbeds… With the well and cistern combined, we can manage about six weeks of drought. Due to its size, the system can also capture heavy rainfall.

Is it cost-effective? Eventually, yes. But that was not the reason we installed it. We couldn’t supply irrigation from the fresh water line anyway because of the flow rates.

Why do you pump the well water into the cistern first instead of irrigating directly from it?

Not enough backfill, filtration, distribution, and buffering. Also, it would be redundant since rainwater collection is also required.
We operate the irrigation (meaning at the end of the zones and not just on paper) with 18,000 L/h (4,755 gallons per hour).
