The idea may have seemed mad, but after all, the beer is called the Madman of Bruges, or Brugse Zot in Dutch.

With the help of crowdfunding efforts among some 400 Madman fans, the dream of building a beer pipeline through the Belgian city of Bruges is becoming real.

"You have to be a bit crazy like the beer to do such a project. I just had the money for that, and I liked it. So I went crazy and gave the money to the brewery," said restaurant owner Philippe Le Loup, who poured $11,000 into the pipeline.

Brewer Xavier Vanneste got the idea four years ago to pump beer from his Bruges brewery to a bottling plant outside of town in a pipeline instead of having hundreds of trucks blighting the cobblestoned streets of the UNESCO-protected medieval city.

What at first seemed like an outrageous dream, began to seem possible when Vanneste started talking to local beer enthusiasts.

Jokes were coming in fast, with people saying "we are willing to invest as long as we can have a tapping point on the pipeline," Vanneste said. "That gave us the idea to crowdfund the project."

Thanks to Le Loup and others, he is now staring at the one end of the pipeline, which beginning in the fall will start pumping some 4,000 liters of beer an hour toward the bottling plant, 2 miles away in an industrial zone.

"That is a lot of beer, more than you can drink in a lifetime," said the owner of De Halve Maan brewery, which in addition to Brugse Zot is also famous for its Straffe Hendrik beer brand.

Sending the pipeline along streets where customers could siphon off their favorite suds was too utopian even for Vanneste, but he came up with the next best thing: IOUs with a lifelong drinking guarantee.

"We have several formulas: bronze, silver and gold," he said. "If you put in 7,500 euros ($8,350), you will receive for the rest of your days, every day one bottle of Brugse Zot."

For many, that offer was hard to refuse. About 10 percent of the total $4.5 million investment for the pipeline has been financed through crowdfunding. With it came a popular surge of support that has stood Vanneste in good stead.

With a warren of municipal, regional and federal laws governing the picturesque city, building approvals are often laborious to get. Not, however, for a beer pipeline as authorities realized the whole community was backing it.

The city also stood to gain. In between the city's beguinage houses and Our Lady's Cathedral, the De Halve Maan brewery has given the sometimes overly touristy city a sense of real life. Vanneste could have done what so many others have â moved out of the city with its canals, gabled Gothic houses, horse-drawn carriages and restaurants with menus in six languages.

Now, he looks forward to the best of both worlds â a historic brewery in a gorgeous location and an environmentally friendly way of transporting his brews out to the bottling plant, which will allow him to continue to grow without damaging the city.

But it's not only Vanneste's family business that is growing. The generous contributor to the project, Le Loup, sighed as he glanced at his own paunch.

In broken English, he said, "You can see that in my belly, I am a bit more beer fan."
