The next time the Regional Water Authority needs to test the flow of the city's fire hydrants on a weekday morning (or any time), a process that leads to dirt entering the water pipes of neighbors so that brown sludge pours out of their faucets when they turn them on to make coffee/brush their teeth/take a shower -- I wonder if maybe, just maybe, someone might give the people in affected neighborhoods some advance notice? Because having MUD coming out of your faucets instead of water is not the most pleasant surprise when you're trying to get ready for work or school. Or maybe this kind of testing could be done late at night, or in the middle of the afternoon? But in any case, with some ADVANCE WARNING? Would that be possible?
