The sun is out, the torrential winter storms are becoming a distant memory, and all eyes are on spring and summer. And yet even though our reservoirs are at healthy levels, it is still critically important that we strive to restrict our water usage to allow for future years that will invariably bring us less water than our county will need. In light of this I felt it important to point out that with just a few small changes in your home, you can cut your water bill by half. And so, without further ado, here are the top seven ways to reduce your water consumption:
1. Low-flow faucets and showerheads
Low-flow faucets have a flow rate of 1.5 to 2.5 gallons per minute (gpm), compared to 2.5 to 5 gpm for standard faucets. For showerheads, select models that use 2.5 gpm or less. Some showerheads manufactured before 1992 had flow rates of up to 5.5 gpm, so if you have one of these older models in your home, consider switching to a newer version. You could save 20 to 25 gallons of water per shower.
2. Low-flush toilets
More and more manufacturers are offering low flow toilets - some equipped with dual flushing mechanisms and others with pressure assisted systems. Kohler’s Power Lite toilets, for instance, allow users to select either a normal 1.4-gallon flush or a super-low 1.0-gallon flush, so you never use more water than you need. Kohler notes that the toilet can save 2,000 gallons of water a year. Sloan’s FLUSHMATE pressure assisted technology can be found inside toilets from all leading manufacturers. The newest FLUSHMATE IV uses less than 1.0 gallon per flush without sacrificing performance and saves up to 45% more water than conventional technologies, according to the manufacturer.
3. Hot water recirculator
For a hot shower, you first have to displace the water that’s gone cold in the pipe — between 1 and 5 gallons — which heads right down the drain. To prevent cold-water dumping, you can install a recirculating pump, which will rapidly pull hot water from the water heater while simultaneously sending cooled-off water from the hot-water lines back to the water heater. In addition to having the convenience of hot water on-demand, the system conserves water and saves energy. A typical system costs less than $400 to install.
4. High-efficiency appliances
The EnergyStar label is the gold standard for efficient energy use among appliances, but the designation also indicates water-efficiency for dishwashers and washing machines. The Energy Star-rated Whirlpool Gold Super Capacity Tall Tub Dishwasher, for instance, uses just 6 gallons per cycle, not 12 to 14 like older models, and its soil sensors ensure that wash cycles use less water if dishes aren’t as dirty.
5. Rainwater collection system
Using a non-asphalt roof as a catchment area, a rainwater collection system funnels water into a cistern, then sends it through a series of micron filters and an ultraviolet bath to kill bacteria. Instead of spending money on a water bill, homeowners simply pay for the electricity needed to pump water from their cistern into their home’s regular plumbing system. Even a brief rain event on a 2,000-square-foot roof surface can add 650 gallons to the cistern.
6. Zoned irrigation controllers
While indoor water use has been dropping since the early 1990s, outdoor residential water use has climbed to 50 to 70 percent of total water demand. The biggest sponge is your lawn. To control the amount of water you use outside, consider investing in a multi-function timer that can be programmed to water different zones, like trees, shrubs, flower beds and turf. Changing your irrigation schedule with each season also will reduce overwatering and runoff.
7. Lawn humidity sensors
Another way to prevent overwatering is to install a relative humidity sensor, like the WeatherMiser, from Weathermiser Energy Efficiency Corp. It monitors humidity and evaporation and electronically interrupts your sprinkler cycle if moist conditions render watering unnecessary. A more high-tech version is the WeatherTRAK system, which has a controller that receives up-to-the-minute satellite data on weather conditions for your area. It then adjusts its irrigation of your landscape accordingly.
