Once the size of cistern has been determined, it can easily be modeled in many open source and proprietary applications. For planning purposes, a RWH system can be integrated into a site plan as a storage element, using the TTT.
| Stage Storage | |
|---|---|
| Storage type | No removal |
| Catchment (roof) | 100% impervious |
| ? | Lined |
| Underlying soil | Doesn't matter |
| Evaporation factor | 0 |
| Suction head (mm) | 0 |
| Saturated conductivity (mm/hr) | 0 |
| Initial soil moisture deficit (fraction) | 0 |
The dimensions of the rainwater cistern can be placed into the fields:
The Curves table is designed to accommodate ponds of roughly conical dimensions. A rainwater cistern is usually cuboid or cylindrical in shape, so that the area (m2) will remain the same throughout the depth. | |
