CTI was asked to provide preliminary pool design assistance by Aquatic Development Group (ADG) in New York, along with the owner’s architect, Chris Jones in North Palm Beach, FL. The pool equipment was purchased from White Water in Canada.
A major element of the innovative wet-weather diversion and treatment scheme at the Moccasin Bend Wastewater Treatment Plant in Chattanooga, Tennessee, is the Influent Relief Pump Station. The pump station has an initial capacity of 80 mgd (expandable to 120 mgd with two additional pumps). Innovative wet weather screens with 4-mm openings are provided. The design of the station provides for discharge of the collected screenings back to the influent channel, where they are directed downstream to the main plant bar screens.
Water Treatment Plant Expansion 15 Mgd with Membrane Ultrafiltration
The Duck River Utility Commission (DRUC) Water Treatment Plant (WTP) is currently rated at 7.5 mgd. The WTP receives its supply from the Normandy Reservoir in Coffee County, Tennessee and serves over 17,000 customers in Tullahoma and Manchester. DRUC needed to expand its WTP to 15 mgd and eventually 22.5 mgd. The first phase of the expansion was the design of a new chemical feed building, including all new chemical feed systems.
The Duck River Utility Commission (DRUC) Water Treatment Plant (WTP) receives its supply from the Normandy Reservoir in Coffee County, Tennessee and serves over 17,000 customers (taps) in Tullahoma and Manchester. DRUC needed to expand its 7.5-mgd WTP to 15 mgd and eventually 22.5 mgd. The first phase of the expansion was the design of a new chemical feed building, including all new chemical feed systems - pumping, piping, bulk and day tank storage, spill containment, instrumentation, chlorine gas scrubber, etc.
The six (6) rectangular primary clarifiers for the City of Massillon's 12 MGD Wastewater Treatment Plant were built in 1938, and consisted of cast iron chain with wooden flights, helical scum skimmers, and steel effluent weirs. The primary sludge removal system required rehabilitation using modern corrosion resistant construction materials such as plastic chain and fiberglass flights and weir troughs.
Moccasin Bend Wastewater Treatment Plant Liquids Handling and Biosolids Handling Upgrade
In order to handle increased flows from the expanding collection system and the construction of $40 million in combined sewer overflow (CSO) abatement projects, the City’s 65-mgd (120-mgd peak) wastewater treatment plant needed a major expansion. The joint venture team of CTI-POH was selected to study, design, and provide construction services for the expansion. Secondary treatment plant capacity was increased to 140 mgd, with an additional wet-weather treatment capacity of 120 mgd, for a total treatment capacity of 260 mgd.
During the annual Riverbend Festival, access is needed from the walkway pier structure at Ross’s Landing to the Coca-Cola stage. CTI was retained to engineer a “gangway” for this access. The stage is a floating structure and is only present during the festival; therefore the bridge had to be designed to be easily erected and disassembled. Because the elevation of the river fluctuates, the connection had to also allow for vertical movement. Its half-trough truss style design allows the main trusses to be part of the guardrail.
CTI assisted Catoosa County with the concept layout, design and permitting for a community park adjacent to the historic Old Stone Church on Highway 41 near Tiger Creek in Catoosa County.
