北卡罗莱纳州阿什维尔的比尔特莫尔庄园
比尔特莫尔庄园的地下水供应井
比尔特莫公馆 是美国最大的住宅，面积为178,926平方英尺. Much has changed with the home and its grounds since it was first constructed in the late 1800s. 今天, 有两家旅馆和许多餐馆, 更不用说增加的访问量了, water demands for the Biltmore Estate have grown substantially due to the development of additional amenities for tourism at the estate. 当比尔特莫尔建成的时候, 它处于技术的前沿, 包括电力, 电梯, 还有一个室内恒温游泳池. But when the house was built, indoor plumbing was not common.
When the estate and house were built the estate developed its own water supply to provide for the needs of the Vanderbilts. The water system supplied for the demands of the house’s indoor plumbing system including 3 kitchens and 43 bathrooms. The estate’s water supply consisted of a totally undeveloped watershed that supplies water to the Busbee Reservoir. A 2.2-mile-long water line conveys water from the Busbee Reservoir to the Lone Pine Reservoir located on a hill above the house. A state-of-the-art sand filtration system treated the water prior to use. This system met the estate’s needs until the late 1980s when new regulations required the estate to connect to the 阿什维尔市’s water supply.
地产的增长, 对额外供水的需求, and the dependence on a single water supply line from 阿什维尔 to the Estate raised concerns of vulnerability. McGill was commissioned by the Biltmore Estate to identify options to address potential susceptibilities of the water supply system.
所面临的挑战
水 demands for the Biltmore Estate are over 6 times greater than it was 30 years ago, 从20岁开始,从1990年的每天1000加仑(GPD)增加到每天125加仑,今天的国内生产总值. Historically, the estate purchased 100% of its potable water supply from the 阿什维尔市. Managers became concerned with the vulnerability of the single 阿什维尔市 connection, as well as the negative impact on tourism if a service line break were to occur or drought conditions resulted in “dirty” water for periods of up to 2 or 3 days.
解决方案
麦吉尔的 水工程队 assisted the estate with the preparation of a preliminary engineering report to evaluate options to reduce vulnerability. Two options considered included a second water line connection with the 阿什维尔市 and the development of groundwater supply wells.
小区选择了地下水供应井方案. 麦吉尔, 考尔兄弟 conducted field observations of the estate property and underlying geology and selected two potential well sites. Our staff obtained well site approval from the Public 水 Supply Section of NCDEQ-DWR. The team developed two deep water wells, each approximately 700-feet deep. Safe yield testing indicated a yield of 150 gallons per minute (GPM) or 108,000 gpd for each well. McGill completed a well water analysis and that showed only disinfection was needed for treatment prior to utilization of the wells.
McGill designed and obtained permits for distribution system improvements to connect the two wells into the Estates system. 改进包括大约17项,6000英尺(LF)的6英寸和8英寸的水线, a chemical storage and injection system for disinfection and a new, 200,000-gallon prestressed concrete water tank to provide additional system storage.
结果
The new system was successfully put to the test when the 阿什维尔市 had a major water line break, shutting down supply of water to the estate for over 30 hours. 新井能够供应152口,900 gallons of water on the first day after the break and 162,500加仑在休息后的第二天, 谁能提供100%的地产需求, 不会造成服务中断.
Providing cost-effective alternatives for our clients has been a benchmark for McGill. Helping Biltmore Estate find and develop the two water supply wells and the additional water distribution system infrastructure to supply the water supply needs for the estate’s operations and to reduce vulnerability to supply interruption is a perfect example of the services McGill provides our clients and our industry. 水 is life and it not only protects public health, but drives the economy.
比尔特莫尔庄园吸引了我.每年400万游客, 直接和间接, 结果是超过6,700 jobs in the 阿什维尔 area and an estimated economic impact of $583.2016财年为200万美元. The Biltmore comprised 23% of the tourism industries economic impact in Buncombe County (Biltmore社区影响报告(2016).
