Constructed in 1975, the existing Raccoon Valley Wastewater Treatment Plant (WWTP) is an extended aeration variation on the activated sludge process permitted at 0.3 MGD capacity.

The Carter Lakes dams in Tallmadge, Ohio, had been determined by ODNR to have several deficiencies in safety and overall condition which must be corrected to prevent the development of conditions hazardous to downstream residents and properties.  There are two dams built of earthen embankment, built across the same stream. The Lower dam is approximately 600 feet long and 30 feet high across a valley to create the lakes. The Upper dam is approximately 300 feet long and 15 feet high, providing a mid-lake driveway crossing and dividing the water body into two lakes.

This mainline trunk sewer is located in Gorge Park which is part of the Summit County Metro Parks in Cuyahoga Falls, Ohio. The existing trunk sewer ran parallel and adjacent to the Cuyahoga River as it traverses through the steep and rocky ledges of the gorge. The sewer was undersized for its current flows and was subject to frequent surcharging and overflows, especially during wet weather. The existing 24-inch steel pipe aerial sewer was constructed in 1939 with several modifications, repairs and improvements in the interim. Because portions of the original sewer were constructed above grade on piers, it was subject to frequent strikes and main breaks from falling trees followed by large sewer overflows to the river. These overflows could sometimes last for days before the City became aware of the problem and was able to access the remote site with the necessary equipment to repair it.

The purpose of the project is to provide sanitary sewer service the business areas zoned (B-3) and the residentially zoned (R-1c) areas located in the southwest corner of the City of Canton. CTI provided a preliminary design report, design, construction administration services for the Faircrest Street SW Lift Station and Sanitary Sewer Project.

In this small historic town, many students live within walking distance of the elementary, middle, and high schools located in the central business district. The school system does not operate school buses, and until recently there were no sidewalks. This led to traffic congestion and potential safety hazards.

The Chickamauga-Durham Railroad once provided rail access from historic Chickamauga in the Tennessee River Valley to the top of Lookout Mountain. The abandoned right-of-way is now available for recreational use.

For generations, Floyd County residents have enjoyed an ample supply of high quality groundwater. Due to development within its recharge area, one well on Fulton Road became contaminated.

With no upgrades since 1982, the campgrounds of Chattanooga’s popular state park were overdue for updates.

DeNovo was retained by MeadWestvaco (MWV) Corporation to provide environmental design and remediation construction services at the Chattanooga Coke Site, located on a 24-acre site on southside area of Chattanooga. CTI was then engaged by DeNovo to provide consulting services.

The existing Lake of the Woods pump station was a 25-year old below ground flooded suction wastewater pumping station. The City desired to have this station replaced with a more modern maintenance-friendly design.

CTI was engaged by the City of Chattanooga, Tennessee, to update the Wastewater Facilities Plan for the Chattanooga regional sewer system. The original Chattanooga, Tennessee-Georgia “201 Facilities Plan” was written in the 1970’s and provided the “blueprint” for one of the largest regional wastewater systems in the Southeast.

CTI designed approximately 1/2-mile of 5-foot-wide sidewalk along Highway 166 in Fulton, Kentucky. The sidewalk was planned to provide residents of an assisted living facility, many of whom use wheelchairs or scooters, access to the commercial district without traveling in the roadway. This road crosses two streams via box culverts. Initially, the plan was to lengthen these culverts to accommodate the sidewalks.

When Tennessee American began planning to construct 1,000+ LF of new water lines on 100+ percent slopes to serve Lookout Mountain, it became apparent that the project would in some ways be as challenging as it was when the original lines were constructed up the mountain over 100 years ago.

CTI assisted with the installation of two canoe launches at Camp Jordan Park along West Chickamauga Creek.

Following the failure of numerous septic systems in the project area, CTI assisted in the procurement of grants for the installation of sewers necessary to eliminate public health hazards.

55^th Street NE in Canton functions as a regional collector, providing access for thousands of drivers that live in northeastern Canton and the surrounding areas. It is a way to work, a way home, and a way to shopping and dining.

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.

To allow access from historic/commercial areas west of the Harpeth River to walking/biking trails on the east, the City of Franklin, Tenn., needed a pedestrian bridge.

The City of Chattanooga Landfill on Birchwood Pike incorporates multi-layer liners, leachate pumping facilities, a gas collection system, a wheel wash station, and other elements designed to protect the environment in and around the landfill.

Pursuant to a Consent Order from TDEC, the City of Chattanooga retained CTI to perform an evaluation of three subbasins in the Hixson area. Included in the scope are over 239,000 LF of pipe from 8 to 48 inches in diameter plus over 1,450 manholes. CTI subcontracted with Compliance EnviroSystems for the SSES field services. Coordination, design, and construction phase services (administration and site) are provided by CTI.

Older portions of this well-established subdivision were constructed without the benefit of a complete storm water system. Runoff into these areas increased as a result of paving and grading in newer parts of the development. In the older areas, the streets served as drainageways, eventually overflowing into yards and homes.

The difficulties associated with this project included providing water to plant processes while the tank was being repaired, minimizing overspray from blasting and coating operations and performing the work with the least amount of interruptions to the operations of the treatment facility.

Having a single pump and well, the Town of Benton needed a second source of water. After attempts to construct a second well, the Town deemed it more economically feasible to install an interconnection with a neighboring utility.

A new combined water treatment plant and distribution system was designed to provide water to the entire park after evaluating the option to connect to an existing water distribution system in the area was determined to not be feasible.

When a major travel center was selecting the site for a $7 million facility, the provision of sewers was a major factor in its decision.

The Carey Village Improvement Project (Carey VIP) is a streetscape beautification project to provide aesthetic and functional improvements to the roadway and utilities infrastructure in the central downtown corridors, utilizing federal scenic enhancement transportation funding and Ohio Public Works Commission infrastructure replacement funding.

When TDOT announced plans to demolish the existing SR 2 bridge and construct a new bridge over Nickajack Lake on the Tennessee River a short distance away, the Town of Jasper was responsible for not only realigning the roadway approaches and addressing other transportation issues but also for relocating water lines and utilities associated with the bridge crossing. The town retained CTI to design a solution that would allow the existing water lines to remain in service for 2 years or more while the new bridge was constructed, and new lines to operate immediately when the new structures was complete, ensuring no interruption in service.

For many years the treatment plant and collection system served Harrison Bay State Park well. However, the plant was not designed to keep up with the increasing flows and loads generated by the camping and day use activities at this popular park.
