[OPTI TECHNOLOGY] 클래커마스 카운티에 빗물연못 설치

옵티테크놀로지(OPTI TECHNOLOGY)와 클래커마스 카운티(Clackamas County) 물환경 서비스(WES)는 지난 14일 오래건주 클래커마스 카운티의 수질 및 범람 문제를 해결하기 위한 제휴를 맺었다. 카운티 자체 폭우대비 시스템에 의해 야기되는 상류홍수 위험성을 줄이고, 수질을 개선시키기 위해 옵티테크놀러지와 WES는 빗물연못 3개소에 고도 폭우대비 조절장치를 배치하기로 했다.

Marcus Quigley 옵티테크놀러기 대표는 “현재 설비된 폭우대비 연못의 기능을 강화해 수질을 유지함과 동시에, 향상된 홍수대책 결과를 얻기 위해 WES와 협업하게 되어 기쁘다”며 “기존 폭우대비 시설을 혁신된 방향으로 최적화시킬 기회에 집중함으로써 WES는 미래의 설비들을 만들어내며 국가를 이끌어가고 있다”고 말했다.

기존 3곳의 빗물연못은 계속해서 해피밸리(Happy Valley)시로 국지적 범람을 유발하고 있는 가운데 이번 프로젝트는 연못의 시설개선을 염두하고 있다. 기존의 폭우대비 홍수조절 계류는 빈번한 홍수 사태에 의해 연못 저장량의 초과를 야기했다. 실시간 NOAA 강수량 측정에 의해 유량이 자동으로 조절되는 발전된 CMAC기술은 연못의 효과적인 수용량 증가를  가능케 할 것으로 기대된다.

STORMWATER POND RETROFITS IN CLACKAMAS COUNTY, GA. ASSISTED BY OPTI TECHNOLOGY

Opti and Clackamas County Water Environment Services (WES) today announced a partnership to address water quality and flooding concerns in Clackamas County, Oregon. Opti and WES will deploy advanced stormwater controls at three stormwater ponds to enhance water quality while reducing upstream flooding risk caused by the municipal stormwater system.

The partnership formed through the CMAC At Scale Initiative, an in-kind funding opportunity provided by Opti and the Water Environment & Reuse Foundation's Leaders Innovation Forum for Technology (WE&RF LIFT). The goal of the initiative is to demonstrate the stormwater management benefits of continuous monitoring and adaptive control (CMAC) technology, a cloud-based solution to a range of stormwater management challenges. WES, on behalf of Clackamas County Service District No. 1, is one of ten organizations accepted into the nationwide program.

"Opti is pleased to be working with WES to achieve improved flooding outcomes while maintaining water quality goals for Clackamas County by making existing stormwater ponds work harder," said Opti founder and CEOMarcus Quigley. "By focusing on opportunities to optimize existing stormwater facilities in innovative ways, WES is leading the nation in building the utility of the future, now."

The project entails retrofitting three existing ponds that have been consistently overflowing, causing localized upstream flooding in the City of Happy Valley. Originally designed as flood control basins, past modifications to the outlet structures and significant increases in development in the drainage area have caused the ponds' storage capacity to be exceeded by frequent rain events. The addition of CMAC technology will increase the effective storage capacity of the ponds by automatically adjusting water levels based on real-time NOAA rain forecasts.

"Our Watershed Protection program provides storm system maintenance and repair services to property owners so they can benefit from properly functioning infrastructure that supports healthy streams and reduces flooding. We continually have to balance our storm system's performance, and in developed areas often have to manage for a single outcome, either stream health or flooding," said Ron Wierenga, WES Surface Water Manager.  "Through this pilot program, we get to explore innovative technology that instead allows us to do both for a fraction of the cost of building new infrastructure."

Data collected throughout the project will enable Opti and WES to evaluate the multi-use benefit of water quality and flood control from the same size basin. Both partners hope to present the results at local and national stormwater conferences in 2017. The target deployment date of the CMAC retrofits is no later than September 20, 2016.
