It is estimated that close to 50% of the water used by homeowners is used to water landscapes, of which a large part is put on our lawns. It has also been estimated that 20% to 80% of what is used is wasted. With water resources becoming ever harder to replace as each year goes by it is important that we better manage the water that is used, so that it isn't wasted to begin with.
One place to start on the road to better water management would be with the sprinkler clock that we all rely on to water our lawns. Most homeowners only set their clock once a year when they fire up their systems in the Spring. It just keeps on watering the same every week, every month, regardless of weather or temperature changes. This results in overwatering in the Spring and Fall and under watering in the hot months of Summer.
If not used properly the irrigation clock will actually waste more water than they were designed to save. Just like we adjust our thermostats for different times of the year, our sprinkler clocks must also be adjusted according to seasonal fluctuations. Our lawns do not need the same amount of water in April as in July. Run times must be changed throughout the growing season.
