It is hot in the DC Metro area. We have been fortunate to have had a few days of rain recently. here some tips to conserve water thus reducing your water bill from WSSC. :) courtesy resmedia.
1. Water your lawn only when it needs it. An easy test to tell if your lawn needs water is to simply walk across the grass. If you leave footprints, it's time to water. (An added benefit of watering less often is that fewer, deep-soaking waterings encourage deep root growth and stronger turf.)
2. Water in the early morning. As much as 30 percent of water can be lost to evaporation by watering during midday.
3. Set your lawn mower one notch higher to make your lawn more drought-tolerant.
4. Use drip irrigation hoses to water plants, and water in the early morning or evening.
5. Forego the hose and wash your car with a bucket and sponge instead. According to EPA WaterSense, a hose left running can waste as much as six gallons per minute while a bucket and sponge uses only a few gallons to do the job.
6. Keep a bottle of cold tap water in the refrigerator. You'll avoid the cost and environmental impact of bottled water and you'll have cold water available in the summer without running the faucet.
7. Run dishwashers and clothes washers only when they are full. If you have a water-saver cycle, use it.
