"Is Now the Time to Buy a Dam for Your House?"
AquaDam runs $20 per foot for the shortest option, 30 inches, and $50 per foot for the tallest, 4 feet, plus shipping fees and taxes. Government entities pay the same price as individuals, Wennerholm said. The Texas Department of Transportation spent about $1.2 million on the seven miles worth they purchased, according to DOT spokeswoman Veronica Beyer. The average home needs 300 to 400 feet of AquaDam, while a business might need more, depending on its size. A homeowner can expect to spend much less: $8,000 to $12,000, on average.
