摘要

该研究评估了静态管理,即没有计划的定期蓄水维护(不疏浚沉积物),称为 SC1,或有维护,称为 SC2。第二种方法是在 SC1 和 SC2 方案中应用实时控制(RTC)技术进行动态管理,分别称为 RTC-1 和 RTC-2。采用 RTC-1 和 RTC-2 方法对 UCT 大坝进行动态管理后,产量分别增加了 2.1 毫升和 1.1 毫升。此外,RTC-1 和 RTC-2 方法在保持雨水收集系统所需服务水平的同时,将容积可靠性分别提高了 5.3% 和 2.5%。SC1 和 SC2 可分别节水 21.15 和 21.45 ZAR/kl,而 RTC-1 和 RTC-2 可分别节水 19.35 和 19.45 ZAR/kl。因此,与 RTC 相比,静态配置可节水约 9%。此外,与 RTC 配置相比,静态配置收集雨水的单位成本相对最低。尽管有这一发现,但 RTC 系统在重塑雨水收集系统以同时实现节水和雨水管理方面展现出巨大的潜力。

Toward a water-sensitive precinct with stormwater harvesting: a case study in South Africa
The study assessed static management, i.e., without planned periodic maintenance of the storage (no sediment dredging) denoted as SC1, or with maintenance denoted as SC2. The second approach was dynamic management based on applying Real-Time Control (RTC) techniques to scenario SC1 and scenario SC2 denoted as RTC-1 and RTC-2, respectively. The dynamic management of the UCT dam with RTC-1 and RTC-2 approaches increase yield by 2.1 and 1.1 ml, respectively. Additionally, RTC-1 and RTC-2 approaches increase volumetric reliability by 5.3 and 2.5%, respectively, while maintaining the required level of service of a stormwater harvesting system. SC1 and SC2 results in water savings of up to 21.15 and 21.45 ZAR/kl, respectively, while RTC-1 and RTC-2 could save up to 19.35 and 19.45 ZAR/kl. Thus, static configurations results in water savings approximately 9% in comparison to RTC. In addition, static configurations harvested stormwater at a relatively lowest unit cost in comparison to RTC configurations. Notwithstanding this finding, the RTC system exhibits a great potential in reshaping the stormwater harvesting system to simultaneously deliver water conservation and stormwater management.
