Fix leaks. The most common fixture that leaks is the toilet flapper. Checking for leaks should be part of your overall maintenance plan and should be done on a regular basis. Perform a water audit. Take a look at your water meter when no one is likely to be using water. If the meter is moving, you have a leak.
Install water-saving devices. Can you transform your single flush toilets to dual flush with a kit? How about installing a Smart Faucet in every bathroom? The EPA has rolled a complete line of water saving fixtures under its WaterSense label, however, but these are merely minimums. Individuals should go beyond the minimum by installing 1.5 gallons per minute (gpm) shower heads when the WaterSense minimum allows shower heads with flow rates of 2.5gpm. Rebates may also be available from your local utility to promote the installation of new high efficiency toilets that utilize 1.28 gallons per flush or better.
Upgrade to water saving appliances. Old dishwashers and top-loading washing machines are incredible inefficient, utilizing as much as 25 gallons per load of dishes and 35 gallons of water per load of laundry. New high-efficiency models utilize a fraction of the water. Dishwashers in the two gallon range are very effective and front-loading washing machines use about a third of the water of what top-loaders use and rebates may be available. The less water an appliance uses, the less electricity and natural gas that will be needed to heat that water.
Rethink landscaping. Plant what’s appropriate for your region and you will reduce water consumption, increase habitat for native species and raise the value of your property. Re-landscaping is a big expense, but you are paying to water and maintain plants every year, year and year out, when you could be pocketing the money you currently budget for water.
