3.8 Leakage per KM Mains (LeakMain)¶
3.8.1 Inputs¶
For each DMA:
- CARL
- Length of mains (Lm)
3.8.2 Units¶
- Input, CARL: L/s
- Input, Lm: [km]
- Output: [m3/(km*year]
3.8.3 Formulas¶
- \(LeakService=\frac{\frac{CARL*86400*365}{1000}}{L_{m}}\)
3.8.4 Aggregations over regional zones¶
- No aggregation if CARL is using MNF. Otherwise, use aggregated regional values from CARL and regional aggregations of LM to compute LeakMain at regional level.
