<prompt> Human: Im sick of paying huge water bills for this place. Our toilets are 1.6Gpf. We dont have a dishwasher. My roommates are strangely fast to defend how expensive our water bill is, saying we use a lot of sink water and stuff like that. But I mean 12.2 thousand gallons... just doesnt seem possible. Our landlords are notoriously shitty. Advice?  <response>: 12.2 thousand gallons is about 400 gallonsday.Thats about 100 gallons per person per day. A shower with restrictor will flow at about 2GPM, so if everybody showers for 15 minutesday, thats about 30 gallons per person. Add a few toilet flushes and youre up to around 40 per person per day.You probably have somebody that runs a load of dishes or a load of wash every day. Thats enough to put you over that number.
