And while there are many actions we can take to reduce water use, here are five most effective and easy to adopt practices we can use to conserve water today.
1. Let your lawn go dormant
The best way to save water outdoors during a drought is to let your lawn go dormant. The lawn will turn brown during dormancy but it will regain its color once the rains return. Most healthy turf grasses can be left dormant for 3 – 4 weeks without the grass dying. If drought conditions last longer than 4 weeks, water should be applied to re-hydrate the grass enough to keep it alive. Water sufficiently to wet the soil down to 5 inches. This small amount of watering will not restore the grass to its natural green color but will keep it alive until the rains come.
Some homeowners wince at the prospect of seeing their beautiful green lawn turn brown, and some homeowner associations have restrictions about letting lawns go dormant. One option which is becoming popular is to spray a non-toxic dye on your lawn which will give it a rich green color while the grass remains in a dormant state. The application is simple, using a hand sprayer, but be sure to apply the spray when there is no wind.
If you’re re-seeding bare spots or seeding a new lawn, be sure to use a drought-resistant grass seed. New varieties of grass seed, such as Eco-Lawn, have been developed to thrive in drought conditions. Eco-Lawn is also low-maintenance and does not require fertilizers or frequent mowing.
2. Hand water your garden and shrub beds
Hand watering your garden and shrub beds saves up to 40% of the water used when compared to sprinklers, since sprinklers apply water across the entire swath they are set to cover. In a garden, the pathways take up much of the ground space, and do not need watering. And by not watering the pathways you won’t need to weed them since the weeds will dry up and wither. Hand watering also delivers all the water right where it is needed, unlike the sprinkler which loses some water to wind and evaporation before it reaches the ground.
Another benefit of hand watering a garden is that some vegetable crops, such as tomatoes, do better when their leaves are kept dry. Hand watering lets you direct the water beneath the leaves and this reduces water-born fungal diseases on vulnerable crops. Watering your garden by hand also gives you time to observe the beds more closely and to see any weeds that need pulling, any pest-ridden foliage that should be plucked, or issues with the plants which may need attention. I enjoy hand watering my garden early in the morning as a peaceful meditation to begin the day.
An alternative to hand watering is to use soaker hoses or drip systems. These methods let you deliver water to specific areas, similar to hand watering. Soaker hoses and drip systems can also be put on timers which are easily installed on your hose spigot. Timers enable you to water your garden and shrubs while you are away from home.
3. Wash your car using a bucket for water
During a drought, people understand that it’s wasteful to wash cars on a regular basis, so driving around in a dusty car is socially commendable. When the car must be washed, fill a bucket with water and use a sponge to apply the water. Refill the bucket to rinse, again using the sponge to apply the water sparingly. A quarter cup of white vinegar can be added to the water to reduce streaks, and this solution does not need further rinsing.
Commercial automated car washes are becoming more efficient since some operators are able to recycle used water, but these facilities still use much more water than the simple bucket method. An alternative to hand washing your car with water is to use a ‘dry wash’ car cleaning product which you’ll find at most auto supply stores.
4. Keep drinking water in a jug in the refrigerator
At home, we typically run the tap until the water runs cold every time we want a drink. By simply decanting tap water into a large container, or individual bottles, you can save as much as 50% of water used for personal drinking. Besides the obvious benefit of conserving water, keeping water in the refrigerator has two additional benefits – the water is cooler than it would be from the tap, and the practice of decanting water from the fridge helps families wean themselves of the wasteful practice of buying water in individual plastic bottles which eventually clog landfills and add to the burden of plastic waste.
If you plan to go hiking or camping close to any natural water sources such as streams or lakes, you can replace the need to carry bottled water by using a LifeStraw, the personal water filter which filters water for safe drinking from rivers, lakes or other bodies of water.
5. Apply mulch to plants, shrubs and ornamental trees
By covering the soil with mulch around the base of plants, the evaporation of water from the soil is greatly reduced. Plants can better survive a drought when mulched, and require less frequent watering. There are many different materials that can be used for mulch, but care should be taken to not use materials with weed seeds or materials which do not ‘breathe’, such as plastic sheeting. (Using plastic sheeting will solarize the soil, killing beneficial organisms in the top layers of soil.)
Even houseplants and container gardens will benefit from mulch. Just add a loose layer several inches thick. Outdoors, mulch incorporates readily into the soil so it may need to be reapplied after a few weeks. Sometimes mulch will attract and harbor destructive insects such as pill bugs or silverfish, and if this occurs then simply pull back the mulch for a few days. Once you get used to using mulch you’ll want to use this method regardless of drought conditions, since it’s so easy to apply and reduces the need for regular watering. Mulch also supresses weed growth which is another bonus.

The drought currently affecting over half of the US mainland is not an isolated weather anomaly. Climate scientists have been warning of a drying trend throughout much of the US as a consequence of climate change, and have referred to this years’ drought as the ‘new normal’. We each need to develop long-term plans to address recurring droughts. Homeowners can easily learn to apply the 7 Principles of Xeriscaping, for example, to convert their properties to low-maintenance, drought-resistant landscapes. Urban dwellers can also contribute to conserving water by familiarizing themselves with simple, effective measures such as installing low-flow showerheads and faucet aerators.
