Learn to seek a leak. Many leaks are silent, with no visible signs in or around the house.
Clip the drips! Repair dripping faucets by replacing washers. If your faucet is dripping at a rate of one drop per second, you can expect to waste 2,700 gallons per year. This adds to the cost of water and sewer utilities or can strain your septic system.

If you have a well at home, check your pump periodically. Listen to hear if the pump kicks on and off while water is not being used. If it does, you have a leak.
Insulate your water pipes. You'll get hot water faster and avoid wasting water while it heats up.
Never install a water-to-air heat pump or air conditioning system. Newer air-to-air models are just as efficient and do not waste water.
Retrofit all household faucets by installing aerators with flow restrictors.
Water softening systems should be installed only when necessary. Save water and salt by running the minimum amount of regenerations necessary to maintain water softness. Turn softeners off while on vacation.
