캘리포니아 샌프란시스코 공공시설위원회(SFPUG)가 산 브루노의 도시에 있는 Harry Tracy 수처리플랜트의 지진 및 운영 신뢰성을 향상시킬 수 있는 프로젝트 완료를 발표했다.

이 프로젝트는 26만 명을 위해 지진을 개선할 수 있도록 설계 됐다. 건설의 가장 큰 부분은 새로운 11만 갤런 규모의 처리수 저수지로, 세라 오류 추적을 발견해 재배치하고 완전하게 저수지를 재구축하는 프로젝트이다.

샌프란시스코 공공 유틸리티 위원회의 관계자인 Harlan L. Kelly, Jr.는 “우리는 큰 지진이 일어난 후 24시간 내에 물을 제공할 수 있는 것을 목표로 이 프로젝트를 완성했다”며 “이번 수처리공장은 크리스탈 스프링 저수지에 약 19억 갤런의 물을 저장하여 많은 주민들의 안전을 도울 수 있다”고 말했다.

 

 

 

The San Francisco Public Utilities Commission (SFPUC) of California has announced the completion of a $278-million project to improve the seismic and operational reliability of the Harry Tracy Water Treatment Plant, located in the city of San Bruno. The 43-year-old treatment plant is responsible for treating the drinking water for more than 1 million customers in San Mateo and San Francisco Counties.

 

The project is part of SFPUC's $4.8-billion Water System Improvement Program, which consists of 83 projects across seven counties designed to improve seismic and water supply reliability for 2.6 million people in the Bay Area (see "SF Nears End of $4.8M Improvement Program"). The largest part of the construction was a new 11-million-gallon treated water reservoir. During design, the discovery of the Serra Fault trace directly beneath crucial portions of the plant prompted a significant redesign of the project to relocate and completely rebuild the reservoir in its current location.

 

"The goal of the project is to provide 140 million gallons of water per day, for 60 days, within 24 hours of a major earthquake," said Daniel L. Wade, director of the Water System Improvement Program. "These plant upgrades, including the new treated water reservoir, have been seismically designed and reinforced to withstand a magnitude 7.9 earthquake on the nearby San Andreas Fault."

 

Harlan L. Kelly, Jr., general manager of the San Francisco Public Utilities Commission, added, "The completion of each of these critical seismic projects helps ensure that we'll meet our goal of delivering water within 24 hours of a major earthquake. This particular treatment plant treats approximately 19 billion gallons of water stored at Crystal Springs Reservoir. More than one million residents on the Peninsula would not have access to this supply after an earthquake without these important upgrades."

 

Accordingly, Nicole Sandkulla, CEO of the state-authorized Bay Area Water Supply and Conservation Agency, also explained, "Many of the communities on the Peninsula receive nearly 100 percent of their water from the Hetch Hetchy Regional Water System, and Hetch Hetchy Reservoir is more than 160 miles away. The investments being made in this system today will make local Bay Area communities more resilient and able to more quickly recover after an earthquake."

 

Both the ongoing $4.8-billion Water System Improvement Program and the 24/7 operations and maintenance of the Hetch Hetchy Regional Water System are funded through the retail and wholesale customer rates.
