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.

A minimum consumption of 30m³ (39 cubic yards) per person is set. Only when this amount is exceeded can you apply, according to the regulations, for an exemption from wastewater charges on the excess amount related to the outdoor water tap.
Only in the first year, which was very dry and when we had to water the lawn seed heavily, did we reach 91m³ (119 cubic yards) for 3 people. The outdoor water portion was about 30m² (320 square feet).
In all other years, we had between 15 and 20m³ (20 to 26 cubic yards) on the outdoor water meter, and the total consumption was well below 90m³ (118 cubic yards).
However, we have clay soil. With sandy soil, the water demand is likely to be significantly higher.

Getting a second water meter is not a problem at all. However, there is no exemption from the wastewater fee, no matter what you do. Therefore, all discussions on this topic are pointless.
This is also pointless considering that our stormwater drains directly into a stream and we are not connected to the sewer system at all.

In our case, the stormwater fee will cost about €5000 over 20 years. That’s why a water cistern was installed a few years ago as a DIY project.
Regarding excess water, there were three options.
1. Discharge into the sewer system. However, this doesn’t make sense because the stormwater fee would still apply.
2. Underground infiltration. This would first require approval from the water authorities, which also involves costs.
3. Surface infiltration. This can be done without a permit and was ultimately chosen since underground infiltration was not possible due to too many trees and shrubs in the garden.
Thanks to the DIY approach, this system pays off quickly.
