节约用水策略

菠菜网lol正规平台 was one of the first users of recycled water on the SBWR system and continues 将服务转换到系统. 在过去的20年里,建筑一直在规划中 and constructed with recycled water in mind, and incremental infrastructure improvements that facilitate expanded use of recycled water on campus have been made by both SBWR 和菠菜网lol正规平台. The campus has more than 20 年 of experience with recycled water project planning, construction, staff development, annual cross‐control testing, and four 年认证. In keeping with CSU Executive Order 987 校园 strategic plan for development of the reclaimed water includes execution of operations driven projects that enable new construction to have the resource available when needed.

灌溉

Since the late 1990’s 校园 has taken steps to plan for conversion of campus irrigation to recycled water, starting with the installation of a new 8” water main 1998年的循环. This project helped 校园 lay the groundwork for recycled water use through improved cross control protection, and by dedicating an entire campus 分配回路到灌溉服务.

In 2011, the main campus irrigation was converted to reclaimed water. 这些植物 the landscape master plan were determined after identifying two constituents of recycled 水,盐度和硼. 用于灌溉的循环水平均超过70,000 CCF 每年.

室内管道

In 2003 校园 constructed its first dual plumbed building, the Joint City‐菠菜网lol正规平台 马丁·路德·金. Library (国王库), and in 2005, SJWC installed an 18‐inch recycled water main running east‐west on San Fernando from 12th Street to just beyond 9th Street, w在这里 it reduces to a 12‐inch line and then continues on to serve San 何塞市政厅和国王图书馆. 2011年3月,学校启用了循环水 到国王图书馆. In 2014, the Student Union underwent a major retrofit and expansion 包括增加一个双管道系统. 2017年2月,循环水连接 大楼完工了.
In 2015, 菠菜网lol正规平台 began installation of a new recycled water main running east‐west on San Carlos St from 10th Street to 4th Street that will be able to serve the rest of 校园. New building construction since 2003 is required to include dual plumbing. Campus Village 2 was completed in 2016 and was the first building on the new recycled 总水管连接. 新循环水总管建成后将提供服务 serve Spartan Complex, Student Health and Counseling and Student Recreation and Aquatic Center.

中央

In 2000, recycled water use was approved for use at 菠菜网lol正规平台’s 中央. 的回收 water is used as make‐up water for 校园 chiller plants cooling tower, and replaced the softened potable water previously used as cooling tower make‐up. 通过水 chemistry improvements over the 年, and installation of a multi‐function chemical controller in 2007, water use in the towers today is less than what it was prior to the conversion when softened potable water was used as make‐up.
The use of recycled water for boiler feed at the 中央 eliminates the single remaining largest potable water usage at San Jose State University. 回收物料的用途 water as a source for steam make‐up is an ambitious technical challenge due to the 要求高纯度. The project to convert steam makeup water was completed in October 2017, we converted our existing boilers that generate steam from potable water to recycled water, using our existing reverse osmosis (RO) equipment, saving approximately 每年使用25,000 CCF的饮用水.
The amount of potable water used on campus has been reduced by 43% since 2013, saving 校园 almost $850,000 in water costs and over 110 million gallons of water 每年.

新校园水表系统

设施开发和运营(FD&O)实施新的水表系统 at the beginning of the Fall 2018 semester to monitor water use and to detect leaks 在校园建筑和主要供水系统. 目前,对 leaks only come from observed puddles but the meters will allow FD&O觉知 of leaks in a timely manner and to reduce water waste associated with leaks. 以前的 water meter projects in other facilities departments have shown that the meters save 约5 - 30%的水.

新校园井

San Jose State University has had source wells on campus since the 1940’s, utilizing 我们校园所在的天然含水层. 然而,在校园建设过程中 Village Phase 2 (CV2), the well was covered by the new construction and we switched 使用圣何塞自来水公司. 设施发展 & 操作(FD&O)开始 construction of a new well in the Southwest area of campus with the project aiming 将于2021年完工. Converting back to well water will provide potable water to 几乎100%的主校区. 从井里取水不仅有关联 cost savings to the university but also makes us a resilient campus in case of an emergency (resilience is the capacity of a system to survive, adapt, and grow in the 面对不可预见的变化,甚至是灾难性的事件). 在紧急情况下 我们的校园仍然有饮用水.

喷泉转换为循环水

菠菜网lol正规平台's water fountains using only recycled water were officially turned on after being 不活动3年. Last Spring, 菠菜网lol正规平台 received the 2018 硅谷 水 Conservation 机构奖. 上海大学是第一批使用再生水的学校之一 南湾水循环系统. 自从接受了硅谷的水资源保护 Award in 2011, the work to reduce potable water use on campus has not slowed down. Connecting 校园 to recycled water for irrigation, adding dual plumbing to all new buildings on campus, and switching existing boilers from potable water to recycled water has resulted in saving more than 100 million gallons of potable water over the 年. 

设备改造

In 2009, 菠菜网lol正规平台 completed a water fixture retrofit for most of our faucets, showers, toilets and urinals funded by Santa Clara Valley 水 District.

2030年的目标

  • 完成RW主线并连接其他建筑
  • 用水量减少20% 
  • Increase awareness and influence behavioral changes of water related
