Water crisis: the made-in-USA example that can change everything?

California and Arizona are tackling water shortages by transforming old aquifers into storage basins, but they don't intend to stop there…

Water and innovation go hand in hand and a possible solution to solve the problem of water shortages arrives from the United States, especially in the presence of extreme meteorological conditions.

In fact, for years the aquifers represented one essential source of water. In the rainy periods, the aquifers filled up naturally, becoming a very important reserve during the months of drought.

However, climate change and a growing demand for water soon led to a depletion of these resources which now need to be replenished.

Storage and the question of aquifers

A real emergency, which prompted the authorities to look for a new way to make them more efficient the aquifers now emptied. According to many, underground storage could be a solution and a model to be adopted in many other countries.

The idea is simple: underground there is space, occupied in the past by aquifers, which could now be used to store water reserves. Creating tanks for local supply.

A system already adopted in some towns in California and Arizona, where the reserves of the precious liquid, which gave rise to life on Earth, are also used in a sustainable way to keep watercourses that tend to dry up under control. causing damage to wildlife and vegetation.

The serious water emergency in America

On the other hand, the United States of America has been facing an unprecedented emergency for some time, which has led to the awareness of having to replace and innovate the existing water systems.

The Senate Committee on Environment and Public Works (EPW), ie the Commission for the Environment and Public Works of the Senate, has in fact approved a bill on this issue.

This is the America's Water Infrastructure Act of 2020 (AWIA), a biennial program that plans to invest more than 17 billion dollars in all states for sustainable and new water management.

The goal is not only to improve water infrastructure, but also to control it more intelligently wastewater.

Orange County's trailblazer project

Will the creation of storage basins work? Perhaps it is still too early to tell. Certainly the numbers speak for themselves and an innovation on this aspect is more necessary than ever.

Just think that, in California alone, 85 percent of the population relies on groundwater for supply. With a goal by the Department of Water Resources to annually expand the reserve.

Orange County alone, for example, pumps daily 65 million gallons of water from the Anaheim docks and represents a starting point for experimenting with new research projects on this topic.

The imperative is not to run out underground water systems, used for agriculture, cities and waterways, continuously implementing them with "recharges" that can take place in different ways.

A solution could come from the creation of percolation basins, in which excess rain or river water can collect.

But also the construction of wells above the water table, to allow the water to reach the aquifers.

Yankee innovation and a model to follow

On the other hand, scholars from all over the world agree in affirming that we are experiencing the most serious water crisis of the last seventy years. A clear signal of climate change, but above all a irreversible process which we must take note of.

One relevant figure among many is that provided by the United Nations, according to which in 2030 around 47 percent of the population will be forced to live with a serious condition of water stress.

Italy represents a hotspot from the point of view of climate changes, and for this reason he looks with extreme interest at the changes and innovative projects implemented across the Atlantic.

From the enhancement of the use of rainwater to the total restructuring of the water network, up to the adoption of circular practices with the use of purified wastewater and new irrigation techniques. Ideas and innovations that could also involve the management of sea and its protection, for a more sustainable future and the survival of aquatic life...
