While human civilization has been able to flourish under some extremely harsh conditions, it tends to flounder if it lacks one simple but vital resource: water. Our complex civilization hinges upon our access to water—for drinking, industry, and agriculture.
Droughts are one of the biggest threats to civilization, both in the past and today, while their causes may seem simple on the surface – a lack of water – their underlying causes and solutions are complicated.
The American Red cross identifies four main types of doughts: meteorological, agricultural, hydrological, and socioeconomic. Meteorological droughts are caused by less than typical rainfall. Agricultural droughts are when moisture is present but not ample enough for agriculture and crops. Hydrological droughts are when surface and groundwater levels are below normal. Finally, socioeconomic droughts are when water supply doesn’t meet demand, or when water is present but cannot reach all of the people who need it, often leading to only the wealthy being able to afford potable water.
These four different types of droughts require significantly different approaches to solve and prevent, all with one end goal — supplying enough water for society.
By examining the causes of these droughts, we can begin to find different solutions for preventing and managing drought risk.
Drought-preventative water fixtures
For domestic users, the major uses of water are for bathing and washing or both people and clothing. While agricultural and industrial water use vastly overshadows domestic use, there can still be a significant amount of waste that occurs within households and businesses, and particularly in the pipes supplying households and businesses.
Water-saving fixtures are commonly used in showerheads, toilets, and sinks for household use, but water use in public restrooms often ends up being overlooked. The Sloan Valve company along with Falcon Waterfree technologies actually came up with a solution to prevent urinals from utilizing waters in public restrooms. They created a replaceable Velocity cartridge which eliminates the need for water usage for urinals, all the while eliminating smells and carrying away all the liquid.
It may not be the most glamorous, but the road to a drought-free future starts with tackling even the most minute problems.
The real wastage in domestic supply; however, comes from leaks in the supply pipes. Many of these go unrepaired for extensive periods of time, causing a lot of wastage.
Smart watering systems
Keeping in trend with household and business water use, watering of landscaping and lawns has become common practice in most cities. This is largely done for aesthetic appeal, and it can be a big source of wasted water. Normally this isn’t a concern for cities that aren’t at risk of drought, but measures can still be taken to be mindful of the water that…
