Using low flow devices on showerheads, toilets, and faucets will make a big difference in the amount of water a household uses. For example, an older toilet uses 5 to 7 gallons per flush. New low flow toilets only use 1.6 gallons per flush. Standard showerheads use 5 gallons per minute, while low flow showerheads use 2.5 gallons per minute. Frontloading washing machines will use only 40 percent of the water a top loading washer will use.
Water savings can add up quickly.
Repairing leaky faucets and toilets will also conserve water. Even a small drip will waste many gallons of water in a day.
