We are connected to city water, so when things work correctly, the tank is filled via the pressured city water lines. However, I the economic crisis and corruption has caused the government to cut services, and I sense now the city is not pressuring the water lines like before. We are now too far away from the street to ever get water.
The water truck might only be a one-time luxury, so we are trying to be conservative with it because we know the landlord doesn't like to spend his money.
