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.

Hello,
In my case, it’s even more ridiculous. I pay a fee for stormwater based on the amount of sealed surface area. At the same time, the municipality requires a water meter and charges fees for a cistern used to collect water for garden irrigation, because they miss the fresh water in the sewage system. I just don’t understand this.

Regarding wells, the potential nitrate contamination comes to mind. It’s no issue for watering the lawn, but it might be a concern for those cautious individuals growing vegetables.
I’m still interested in how the original poster will solve the infiltration.
By the way, I may have posted this here before… For sizing a cistern, there are calculation guidelines from relevant manufacturers (Graf…). Input values include garden size, region/rainfall amount, and frequency. The result is the required cistern size.

Regarding infiltration, I talked with a friend who has an overflow system. This means that when the cistern is full and it keeps raining, the water is directed through a pipe into a two-meter-deep (6.5 feet) hole filled with gravel.
Something like that should work for us as well... But as I said, I need to discuss the details with the general contractor. At the moment, we are still very early in the planning stage.

How did it turn out? We are considering the same option— a cistern with an infiltration overflow—because otherwise we would have to pay very high stormwater fees (5,000–8,000 euros over 20 years, with prices tending to rise).
So, we ultimately got a 6,000-liter (1,585-gallon) cistern. The excavation pit was generously dug out and filled with gravel around the cistern. Additionally, a geotextile fabric was placed around it. When the cistern is full, water flows out of an overflow pipe and infiltrates into the surrounding ground.

borderpuschl7 Feb 2018 13:09The soakaway must be approved by the local authority. In our case, the authority required three boreholes for a soil survey at the proposed soakaway location, as well as an infiltration test to measure how much water drains within a certain time. It was significantly easier (and cheaper) to direct the overflow into the sewer system.
