Water Use In Your Home

Piechart of how much water we use in our homes.

Pennsylvania is home to more than 12.4 million residents, 10 million of which rely of a public supply system to provide their water. To meet these needs, Pennsylvania has more than 2,100 community water supply systems. Although the water source for the majority of these systems is ground water, surface water also plays an important role, especially in the larger metropolitan areas.

Each one of us uses about 60 gallons of water per day in our homes, or about 700 million gallons every day statewide. This pie chart, based on national averages, illustrates the percent of total daily water used for each water-using fixture or appliance. Using this information as a guide can help you plan your route to reducing water consumption at home.

What Can You Do in Your Bathrooms?

Nearly 50 percent of a household’s water consumption takes place in the bathroom. Repairing leaky fixtures and installing efficient toilets, faucets, and showerheads can significantly reduce your household’s water use.

What Can You Do in Your Kitchen?

To reduce water use in the kitchen, install a water-efficient faucet and dishwasher. An even simpler, less expensive way of reducing water is to install efficient faucet aerators. Efficient aerators are available in a range of flow rates less than the current standard for faucets (2.2 gallons per minute). Replacing an aerator can be as simple as unscrewing the old one and screwing on a new, more efficient aerator.

  • Install efficient faucets
  • Install water-efficient dishwashers
  • Use your garbage disposal sparingly because most require running water. Compost vegetable food waste instead.
