Hello,
I have a question regarding the offered cistern. Our development plan states the following:
The general contractor suggested that we install a cistern in the garden.
The current offer includes a cistern with a capacity of 4,000 liters (1,057 gallons).
The plot is approximately 540 m² (5,813 sq ft) in total. The house will be roughly 10 m x 11 m (33 ft x 36 ft), plus a double garage of 6 m x 6 m (20 ft x 20 ft), and a terrace...
Do you think this size is too small?
I have a question regarding the offered cistern. Our development plan states the following:
C 3. Water Management
C 3.1 The hardening of open areas should be limited to a minimum. Parking spaces and driveways should be paved with permeable surfaces (e.g., grass pavers, paving with grass joints, gravel turf, or similar).
C 3.2 The uncontaminated rainwater collected on private properties must be retained on the site and infiltrated or used as non-potable water.
Only wastewater must be directed to the sewage treatment plant.
C 3.3 A management concept must be developed and coordinated with SGD Süd, RS WAB, Neustadt for the disposal/use of rainwater that is not significantly polluted.

Well, for example, where we live, we are not allowed to discharge rainwater into the sewage system and are required to install a soakaway or infiltration pit.In this case, a soakaway is probably mandatory. A cistern, however, is initially unrelated to drainage since it only serves as a temporary buffer. Once it is full, the water must be fully discharged. So if a cistern is not required, for example to reduce discharge, I would get a quote for one and then decide if it’s worth the extra cost. Regarding size, I wouldn’t go below 5m³ (around 177 cubic feet) but also not above 8m³ (about 282 cubic feet). The ideal size depends on the intended use. If it doesn’t rain significantly for three weeks in summer, a 12m³ (approximately 424 cubic feet) cistern can still run empty. However, this is quite rare in our climate. If the water will regularly be used for washing cars, bicycles, motorcycles, flushing toilets, or refilling multiple fountains and ponds in the garden, then 10m³ (about 353 cubic feet) might make sense. For example, our pond easily holds the full content of our cistern, and water is only changed every one or two years. Additionally, during summer, about 200 to 500 liters (around 53 to 132 gallons) need to be added weekly.

meister keks8 Feb 2018 23:55A cistern for 1000 euros, a shaft for 500 euros, and a 200 euro hardware store pump—these are the items I have.
I laid down grass the summer before last and watered my property well.
I was completely at ease doing this while everything beyond my property line was grey and scorched.
I haven’t calculated exactly when it will pay off, but assuming that everything gets more expensive, it will eventually pay for itself.

It depends on the region. If the groundwater is not too deep and replenishes quickly enough, this can still be a viable solution. However, in many cases, it is more expensive than a cistern. Additionally, it is not permitted everywhere, and drilling also carries the risk that the groundwater level may eventually drop, causing the source to run dry.
As mentioned, we are not allowed to discharge rainwater into the sewer system. Therefore, I only have the options of either a cistern or a soakaway pit. With the cistern, at least I can use the water for the garden. We will not connect it to the house (e.g., for toilet flushing).
My plan is to drill a well that will refill the cistern when it runs empty.
A 6,000-liter (1,585-gallon) concrete cistern has already been installed and connected to the rain gutters.
