3 1.1 PROJECT BACKGROUND 1.0 INTRODUCTION The Northeast Ohio Regional Sewer District is a political subdivision of the State of Ohio and organized under Chapter 6119 of the Ohio Revised Code. Originally named the Cleveland Regional Sewer District, it was created in 1972 to assume the ownership, operation and maintenance of wastewater collection, treatment and disposal facilities servicing the member communities in the Cleveland metropolitan area. The District owns and operates three treatment facilities: Easterly, Southerly and Westerly. The Southerly Wastewater Treatment Center (SWWTC) is located at 6000 Canal Road, Cuyahoga Hts., Ohio. In 2005, the District commenced with the Comprehensive Facilities Plan (SFP) project with the engineering consulting firm Malcolm Pirnie for its Southerly Wastewater Treatment Center. The SWWTC currently serves approximately 530,000 residents from forty-five (45) tributary communities. The 273-acre site is the largest of the District s three wastewater treatment plants. The original plant began operation in 1927 and the last major improvement program for the upgrading and expansion of the facility commenced in The SWWTC is a tertiary treatment facility that provides treatment by using a two-stage biological process. The first stage treatment includes bar screens, aerated grit tanks, primary settling tanks, aeration tanks and settling tanks. The second stage consists of aeration tanks and settling tanks. The third (tertiary) stage comprises of effluent filtration and chlorination/dechlorination. Second Stage Aeration is designed to treat an average daily flow of 200 MGD and a wet weather flow of 400 MGD. The primary goal of the 2005 facilities plan project was establishment of a prioritized sequence of capital improvements and financial needs for the next thirty (30) years for purposes of ensuring consistent adherence to future regulatory requirements, maximizing treatment effectiveness, and optimizing operating efficiency. In addition to addressing renewal and replacements needs at the plant, the comprehensive facilities plan project included a wet-weather evaluation which analyzed the impacts of the District s Combined Sewer Overflow Long Term Control Plan (CSO LTCP) and identified/recommended necessary plant improvements needed to handle the increased wet-weather flows. The wet-weather evaluation includes a No Feasible Alternative (NFA) Analysis of the Primary Effluent Bypass (PEB). Completed in April 2009; the final report includes a recommended list of projects with associated project costs, recommended schedules, and preliminary design layouts. Design work for Primary Settling Tanks (PSTs) Nos. 1-18, ancillary equipment and processes, the NFA titled ST1, Chemical Feed Handling and Chemical Storage are included in this RFP. Also included is a primary treatment process work plan to construct a chemically enhanced treatment pilot plant at the District s Easterly Wastewater Treatment Plant. The purpose of the pilot plant is to study the performance of the primary treatment process during wet weather flows with chemical and Page 3 of 43

4 polymer addition. The District will operate the pilot plant for a 1 to 3 year period. Existing Primary Treatment Facilities Primary Settling Tanks The existing Primary Settling Tanks (PSTs) consists of eighteen rectangular concrete tanks arranged in two batteries at the north end of the site. PST Nos use chain and flight collectors for sludge removal. PST Nos are equipped with a traveling bridge and chain and flight cross collector. Helical skimming mechanisms are provided for scum removal. Five Access Buildings are located around PST Nos The Access Buildings provide stairway access to the pumping equipment and tunnels. Primary Effluent Flow Control Consisting of three control structures, the Primary Effluent Flow Control provides for flow distribution to the secondary treatment facilities as required by the operating parameters of First and Second Stage Aeration. These structures include: Flow Control Chamber A, located east of PSTs 1-10, measures and regulates Primary Effluent flow into the First Stage Aeration Tanks. It controls the maximum amount of flow that can be sent to the First Stage Aeration Tanks (FSATs). Flow Control Chamber B is located at the southwest corner of PSTs During wet weather events, a fixed labyrinth weir in this chamber diverts flow to the Cuyahoga River as primary effluent bypass. Two primary bypass conduits transport the flow to the Cuyahoga River. Flow Chamber C is located at the southeast corner of PSTs and north of the Second Stage Lift Station. Bypassing the First Stage Aeration Tanks is accomplished through this chamber. Chemical Handling Facility Previously known as the Waste Pickle Liquor Building, this facility consists of storage tanks, chemical feeders, sampling pumps and automatic analyzers for phosphorus. Ferric chloride from this facility is metered into the primary effluent to aid in coagulation. Disinfection Chemical Feed Facility This facility consists of storage tanks, metering pumps, control panels, and distribution lines in order to add Sodium Hypochlorite, Sodium Hydroxide and Sodium Bisulfite as necessary to the plant effluent.
