Welcome to brain Stuff from house stuff works dot com where smart happens. Hi Am Marshall Brain with today's question, why are they replacing all of the toilets in this apartment complex? It's true many cities have conducted a massive drive to replace older toilets with new water saving models. Here's why. A family of four can consume something like three four hundred gallons of water per day on things like bathing, cooking, drinking, laundry, and dishwashing. Old toilets use
about five gallons or twenty leaders per flush. When you consider that a normal person flushes a toilet seven or so times a day, you can see that a family of four consumes more than a hundred and forty gallons of water per day flushing alone. Depending on the article you're reading, the water consumption of toilets represents between thirty and fifty percent of the water consumed by a household each day. The new toilets installed in your apartment use
one point six gallons or six leaders per flush. If you replace those five gallon per flush toilets with these new one point six gallon per flush toilets, you save a huge amount of water. Something like a hundred gallons per day per household for a city. A big reduction like that means that you can delay the construction of new reservoirs and new sewage treatment plants. That's a huge incentive to replace all the old toilets. Do you have
