随着美国一些城市的关键水管和配件老化超过世纪，美国别无选择，只能面对其庞大的基础设施需求。在我们应对水基础设施挑战的过程中，地方、州和联邦各级正在做出价值数百亿美元的政策决定。不仅数百万英里的管道需要更换，我们还必须投资于额外的管道，以满足不断增长的国家不断变化的需求。根据美国水务协会（AWWA）的一项研究，在未来25年内，美国必须在地下水基础设施上投资超过1万亿美元。在未来40年内，这一数字将增长到1.7万亿美元以上。拖延投资只会增加成本，增加灾难性和代价高昂的事故的可能性。
With critical water pipes and fittings aging past the century mark in some American cities, the nation has no choice but to face up to its massive infrastructure needs. Policy decisions worth tens of billions of dollars are being made at the local, state and federal levels as we tackle our water infrastructure challenge. Not only are millions of miles of pipe in need of replacement, we must invest in additional piping to meet the changing demands of a growing nation. According to a study by the American Water Works Association (AWWA), over the next 25 years the United States must invest more than $1 trillion in underground water infrastructure. That amount grows to more than $1.7 trillion over the next 40 years. Delaying the investment will only increase the cost and increase the likelihood of disastrous and costly mishaps.
