Vince Young is college football's

. The University of Texas quarterback had huge expectations placed on him and exceeded them all. I believe Young played the greatest football game I have ever seen. Of course, if I was a USC fan I would probably disagree. Congratulations to my Texas Longhorns, and to Coach Mack Brown for getting the monkey off of his back.

In honor of Texas defeating a great USC team to win the NCAA football championship, I can't help but go with a Texas theme this week. Since you can't invest in the Alamo, what better Texas theme than water?

In a world covered in water we are running out of potable water and ways to transport it. Now, before you start thinking I have been hit over the head with too many chairs in my professional wrestling career, let me give you the facts. Most importantly, I will show you how to make money off of a coming boom in the water business, with

and

Insituform Technologies

( INSU) among my favorites.

You can also buy water rights outright as T. Boone Pickens and the Bass brothers are doing. However, this is a big money game with a lot at stake. How much is at stake? Consider:

Ground water levels in the Chicago area have declined as much as 900 feet in the sandstone aquifer underlying the city and eastern Wisconsin. In Houston ground water has declined about 400 feet. The Tucson and Phoenix areas have seen a decline of 300 to 500 feet.

The Colorado River has not reached the Gulf of California for many years, due to the upstream water needs. Lake Powell has dropped by more than 50%.

Water level monitoring has taken place in some states. However, except for the High Plains Aquifer, aquifers that cross state boundaries have no coordinated level of monitoring.

Ground water supplies roughly 50% of Americans' direct needs. Ground water provides around 40% of the nation's public-water supply. In the past 30 years water demand has tripled while the population has grown by just 50%.

In addition, infrastructure is antiquated at best. A lot of the pipes were laid more than a century ago. It is estimated that the U.S. will need to spend up to $500 billion to replace these pipes; another $300 billion will be need for new water treatment plants. The Environmental Protection Agency estimates that 20% of the water transported leaks out of cracks in the pipes. The ability to fix pipe while still in the ground is what makes Insituform Technologies so special.

The EPA has projected the total capital needs for wastewater infrastructure to be $17 billion to $23 billion a year, up from the $13 billion a year spent now.

And this is not a U.S.-specific problem: The World Commission on Water has estimated annual investment needs in water infrastructure to increase from $75 billion to $180 billion over the next 20 years.

The desalination industry is one key to water shortages; the industry could be a $20 billion industry within five years, with almost three quarters of that in the Middle East. Texas and California have large desalination plants coming online. In Carlsbad, Calif., a planned desalination plant will be the largest in the world.

Pentair,

have done a great job of buying up water-related companies. GE's acquisition of Ionics gave it the best pure play in desalination.

A basket of water stocks has outperformed the

S&P 500

for the last 10 years, but there is still money to be made in all of this. Why? Current forecasts underestimate the amount of money that is going to be spent to upgrade this sector.

Turning Water Into Cash

Pentair is the best pure play in the water sector: 73%-75% of its revenue comes from water. Pentair's main focus is pumps, filtration and purification. The U.S. will have to almost triple spending to update its entire infrastructure and filtration plants; this is not baked into the price of PNR. We have a growth that will explode in the same way the oil industry has seen, the key is to pick the right company, and Pentair is the right company.

Pentair has made several acquisitions to become a major player in the water sector, with the most notable being its $750 million acquisition of Wicor.

In the first quarter of 2005, Pentair's water revenues were $512 million, up 63% year over year. Pentair is benefiting from the Wicor acquisition and growth in North America and China.

Pentair is more than 20% off of its 52-week high of $46.47. It has a forward multiple of roughly 18 based on consensus estimates of $2.20. Put a more realistic 21 multiple on this stock, and you have it reaching its 52-week high again. That is a 20%-plus gain.

I do not currently own shares of Pentair; however, I have set aside 5% to 10% of my portfolio this year for water stocks, and Pentair will most likely be the first.

There are other ways to play the coming water boom. Insituform Technologies is a fantastic company with a great product. It has the ability to fix pipe while still in the ground. The only problem is this company's price is way too far ahead of itself. It may look cheap at less than $20 per share, but not when you look at its trailing P/E of more than 220.

Gol Linhas Aereas Inteligentes

(GOL) - Get Report

. The stock price has appreciated more than 35% since then.

This week, Gol increased 2006 guidance for net revenues, earnings per share and operating margins. This is a great stock, the best airline stock in the world. If you own it here, I wouldn't sell it. However, I think I would wait for a pullback to become a buyer.
