Hello everyone,
Here is the situation:
- Single-family house in the southern Hamburg area; 545 m² (5,856 ft²) plot; 110 m² (1,184 ft²) house footprint; approximately 150 m² (1,615 ft²) roof area (rough estimate)
- Cost for a cistern according to the earthworks contractor’s offer, 5 m³ (1,320 gallons), including delivery and installation, excluding the "interior components" (What does that mean???): €2,150
- Funding from IFB Hamburg: 40%, up to €1,500 --> Net cost: €1,290
Questions:
- Does such a cistern make sense under these conditions?
- At which planning stage should the decision be made? Before construction or possibly only afterwards?
- Does it make sense (also in terms of cost-effectiveness) to supply the toilet flush and washing machine with water from the cistern?
Best regards!
