Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Brown and Caldwell, Inc. for the Real Time Control - Alum Creek Storm Tank project. The City has embarked upon its approved Wet-Weather Management Plan (WWMP) dated July 1, 2005. Recently, the City received approval from Ohio EPA to investigate whether it can meet the WWMP goals and future stormwater regulations with the Integrated Solution (IS). As parallel with the integrated planning, the City continues to undertake several projects simultaneously. This project is one of them.
The scope of work for this project is to implement real-time-control (RTC) infrastructures in the collection system near the vicinity of the Alum Creek Storm Tank to reduce combined sewer overflow (CSO) at the Alum Creek Storm Tank and sanitary sewer overflow (SSO) at Roads End (DSR 244), and to optimize conveyance and storage of the collection system.
The components of the project include the addition and/or modification of several infrastructures to the collection system, which include but are not limited to static weirs, operable weir gates and sluice gates, as well as their instrumentation and control system, and necessary flow monitoring devices. This project also includes design of sanitary sewers to increase flow capacity and eliminate DSR 244 activation to 10-year level of service.
2. THE PROJECT TIMELINE: It is anticipated that a Notice to Proceed will be issued on August 1st, 2014. Detailed Design will be completed by August, 2015, land acquisition will be completed by December 2016, and construction will commence March 2017 and be completed by March 2019.
