Our office just got dual-flush handles for the toilets in the ladies room – hooray! If you flush down, it uses 1.6 gallons of water; an up-flush uses only 1.1 gallons – a savings of half a gallon per flush.
This is great – in our office of 150 people, there are approximately 75 women…that’s a lot of toilet flushing! If you figure each of the 75 women use the toilet three times per day, with three 1.6 gallon flushes, this equates to 360 gallons of water per day. If we all modify our behavior to two up-flushes and one down, this is a total of 285 gallons per day – a savings of 75 gallons per day. Over a year, this is nearly 20,000 gallons of water saved in our office alone!
Growing up in a household with a well and septic system, I am very familiar with the concept of “if it’s yellow, let it mellow; if it’s brown, flush it down!” I can definitely remember to flush down for #2, BUT remembering to flush up for #1 is MUCH harder than I expected. I think I’m remembering only about 50% of the time (even with the little sign there). This is going to take some time to retrain my muscle memory!!
