Septic tank pumping companies love "flushable" butt wipes. Everything that goes into the poop tank is supposed to eventually dissolve and pass through the filter out into the drain field. Once the filter clogs it's another couple of hundred bucks unless you're a do-it-your-selfer with plenty of disinfectant and a stopped up nose.
That got me wondering. If the school was rationing TP, girls likely brought there own, and wipes are more portable than TP. If girls are flushing wipes, that could cause a far more expensive problem than a high TP tab. Also, if there are bidets, girls might not want to use those. They’re not my cuppa. They also might be embarrassed and/or PO’ed about having to ask for TP. This all assumes, of course, that the school is willing to support modern hygiene practices.
