Resist drought by dropping 96 million plastic balls into the lake

To cope with the current record drought, the city of Los Angeles (LA), California, USA has used strange measures to protect the city's water resources - dropping 96 million balls Dark in the city water storage lakes in Sylmar, California.

According to experts, plastic black balls work to protect water from natural impacts like dust, rain, chemicals, and even natural organisms.

At the same time, they work to prevent water evaporation of up to 300 million gallons per year (more than 900 million liters of water) - enough water for 8,100 people in a year.

These balls are about the size of an apple, worth about 8,000 VND. They float on the surface of the water, absorbing sunlight to help limit the evaporation of water.

In addition, these balls also form a layer to protect the surface of the water from animals and prevent the proliferation of algae - agents that pollute water sources.

Balls also contribute to preventing a chemical reaction that creates a cancer- causing bromate compound . This is a compound made of bromine and chlorine under the lake surface, under the sun's catalyst. Some people who absorb large amounts of bromate may experience nausea, diarrhea and abdominal pain.

Dr. Brian White of the Los Angeles Department of Energy and Energy (LADWP) is the father of this strange method. Since 2008, Dr. White's solution has been widely applied by LADWP in open water reservoirs in the summer.

Approximately 20,000 balls were released into the reservoir at Van Norman Complex in Sylmar, California on August 10, 2015.

LADWP engineers are continuing to work on reserves in the Upper Stone, Elysian and Ivanhoe. The objective of the campaign is to reduce water evaporation by up to 90%.

According to Mayor Eric Garcetti, this initiative helps save up to 250 million USD compared to similar methods (over 5 trillion VND), such as separating reservoirs on how to build and divide or cover the lake surface with one layer. fabric can cost more than 300 million USD.

These plastic balls cost only 8,000 VND / fruit .

. but can save for the city budget more than 250 million USD (over 5,000 billion VND)
