The Pig

The Pig System is a tool that scrapes the pipe clean, pushing out all the built-up debris and marine growth.

Next week, we’re releasing a new episode all about the Pig System in Intakes & Outfalls for Desalination Plants.

While this method is more commonly used in smaller-scale oil & gas applications, it’s also essential for desalination.

You might not be too familiar with it, but trust me—this is critical knowledge if you’re designing or maintaining a desalination plant.

So, why is it called a "pig"?

Imagine this: over time, marine life begins to grow all around and inside your submerged intake pipe.

Initially, your pipe—at 2000 mm internal diameter—allows water to flow smoothly to the intake pump station. But as marine life builds up, that diameter can shrink to 1800 mm or even less, causing increased headloss and restricting water flow.

The result?

You’re no longer meeting your water intake needs, which leads to missed capacity, penalties, reputational issues, and disrupted service to end users.

This is where the "pig" comes in.

The Pig System is a tool that scrapes the pipe clean, pushing out all the built-up debris and marine growth.

And when it emerges, it’s covered in dirt, just like a real pig in the mud—hence the name!

Don't miss this episode to learn how the Pig System can be a game-changer, ensuring efficient, uninterrupted water intake and avoiding the messy consequences of unchecked marine buildup.
