The shadow balls have had a cost of $ 34.5 million.
It is the first step in the project to throw 96 million balls into the Van Normam Complex reservoir in Sylmar. It is the first city in the United States to use this measure.
As the mayor commented, "It's a combination of engineering and common sense to save us a lot of money."
The balls are filled with water, which helps them stay on the surface of the water and protect it from sunlight, preventing its evaporation and loss.
They are black, made of plastic, and cost 36 cents each. The balls have a life of 10 years and after their useful life, the company will recycle and replace them if necessary.
The measure may be effective, but we do not believe that the best solution to combat the drought is to use the harmful plastic in colossal proportions. There is an urgent need for an alternative to plastic, it is urgent that governments get involved and take measures, there may be alternatives, they need to be invested and trusted.
