What Are These Black Balls Doing in the Reservoir?

In Los Angeles, a remarkable sight unfolds as a truck releases countless black balls into a sprawling water reservoir. At first glance, it might seem like an attempt to create the world's largest ball pit, but this spectacle serves a far more critical purpose - ensuring the safety of the city's drinking water supply. These black spheres play a crucial role in preventing the formation of a carcinogenic element called Bromate in the water.
The story behind these shade balls begins with Bromide, a harmless substance formed in water from salt. Typically, chlorine is used to disinfect water without any adverse effects. However, introducing Ozone for disinfection led to an unintended chemical reaction, transforming Bromide into harmful Bromate. This discovery prompted officials to take immediate action to regulate Bromate levels in the water supply.
The ingenious solution was to deploy black shade balls. These unassuming orbs, made of high-density polyethylene, block sunlight from reaching the water, preventing Bromate formation. They are both durable and heat-resistant, ensuring they neither degrade nor increase water evaporation. While it may resemble a giant ball pit, this reservoir now serves as a symbol of innovation and resourcefulness, safeguarding the city's drinking water supply and offering a unique visual spectacle to those who witness it.

i heard it was for shade so the water did not evaporate due to drought.

[@DjClarky78]

That was an added bonus, but not the original reason to add them to the reservoir.

Da es Plastik ist, die Frage: Gibt das Material kein Mikro-Plastik ab?

[@GSRTurbooo]

Heart warming to see the use of plastic at such scale ❤️

[@elviesmascarenhas6059]

What if the reservoir was covered with solar panels, electricity generation would have taken place...

[@OpenDeepLearning]

Pidgeons maybe would have sat on them and created poor quality water

[@shfd3832]

Why cant they use chlorine?

[@rmg7623]

Yeah I’m sure those balls are completely safe to bake in the sun above the water. 🤦🏻‍♂️

[@someoneyoullknow4077]

Didn't even watch the video 😂

[@jaliyaat321]

why they cant place square type blocks

[@StreetTramper]

Instead of black balls, build a floating solar panel farm like in Indonesia. Dual purpose, shade and produce electricity

Please tell me the music’s name

[@yyghhh7462]

Please 🙏 add subtitle

[@Sphyxx]

They're swimming leave the guys alone

[@menacereconnaissance7406]

How many balls said in this video? 😅

[@deadskullfacts]

What if someone drowns in it??
