아메리칸 워터의 자회사인 미저리 아메리칸 워터사가 세인트 루이스 카운티 전역의 약 200개 프로젝트와 경쟁해서 2014년 주요 급수 본관 대체품 분야의 새 기록을 세웠다고 최근 발표했다.

이 회사의 7천만 달러 투자는 약 20년 전에 시작한 본관 대체품 프로그램 이래로 파이프 업그레이드의 가장 높은 단계를 대표한다. 거의 4천200마일의 급수 본관은 하루 약 2억 갤런의 물을 나라 전역의 110만 인구에게 배송한다.

 

 

 

Missouri American Water -- a subsidiary of American Water, the nation's largest publicly traded water and wastewater utility company -- recently announced that it has set a new record in water main replacement in 2014, completing approximately 200 projects across St. Louis County.

 

The company's $70-million investment represents the highest level of pipe upgrades since the proactive main replacement program began about 20 years ago. Approximately 4,200 miles of water mains deliver about 200 million gallons of water per day to the 1.1 million people living in the county.

 

Many of the water mains replaced are 50 to 100 years old. Missouri American Water engineers strategically set priorities for water main replacement projects based on several factors -- including the age and material of the pipes and the history of main breaks. Equipment that uses infrared and acoustic technology also helps to evaluate the condition of the water mains.

 

The challenge of aging water mains is national in scope. The Environmental Protection Agency's Fifth Drinking Water Report to Congress estimates that nationally, water utilities will need to invest an additional $245 billion in water distribution systems over the next 20 years to sustain public health and safety.
