Less frequent watering with sprinklers that spray low, broad drops will allow the water to seep into the ground, promoting deeper root systems that better withstand dry weather. In the garden, a soaker hose is the most efficient way to water because it puts water close to the roots and reduces evaporation. Leaving the hose running for 4 hours will use about 1,500 gallons of water. Use a timer to avoid over watering. Mulch flower and vegetable gardens, shrubs and trees to hold more moisture in the soil and to control weeds.
Plant herbs that discourage insects.
Use insect sprays, weed killers and fertilizers only in the amounts listed on the label. Dump soapy or dirty water at least 100 feet from a stream or pond. Each flush of the commode uses 4-7 gallons. An average leaky faucet can waste up to 2,000 gallons of water in a year. Turn off water while brushing teeth.
