I assume you're talking about water leakage? If you are, we're not talking about that because it's such a tiny number as to be irrelevant. "California receives a total of 80 million acre-feet of water per year. Of those, 23 million are stuck in wild rivers ... All urban water consumption totals 9 million acre-feet. Of those, 2.4 million are for commercial and industrial institutions, 3.8 million are for lawns, and 2.8 million are personal water use by average citizens in their houses. In case you’re wondering about this latter group, by my calculations all water faucets use 0.5 million, all toilets use 0.9 million, all showers use 0.5 million, leaks lose 0.3 million, and the remaining 0.6 million covers everything else – washing machines, dishwashers, et cetera."
