Ghetto pool filling

Our pool has been either empty or too dirty to swim in for the past 6 months or so. Every week, the landlady has been telling us it will be fixed in a week. Now, finally, it seems like it may finally be getting filled. But, instead of having a water truck come to fill it, they're siphoning water out of the cistern. Yes, that is the same cistern that we use for showers, cleaning, toilets, and everything else. And yes, the cistern is significantly smaller than the pool. Will we have water for a shower tomorrow morning? I'm not holding my breath. But, at the same time, the water isn't flowing very fast, so maybe.
