Project Area Map:
Summary: Connecting to OARS at Vine Street, the LOT main tunnel will construct about 17,000 feet of 12-foot diameter tunnel at an average depth of 50 feet. It will be mined with a tunnel boring machine (photo) and built with precast concrete segments. There are three main shafts along LOT: Tuttle Park north of Lane Avenue, Gowdy Field near Third Avenue & Olentangy River Road, and at Vine Street.
CIP
The City of Columbus is under two Ohio Environmental Protection Agency (OEPA) consent orders to improve water quality and reduce the potential for human contact with waterborne pollutants by reducing overflows from the sewer system into creeks and rivers during wet weather events. The Department of Public Utilities' plan for achieving the requirements of these consent decrees is described in the “Integrated Plan and 2015 Wet Weather Management Plan Updated Report”. One of the key elements of the plan is the Lower Olentangy Tunnel (LOT).
LOT will assist with several goals outlined in the 2015 plan to address OEPA consent order requirements which include:
- Prevent activations (up to a typical year storm) from seven Combined Sewer Overflow (CSO) structures, located along the lower portion of the Olentangy River by relieving the Olentangy Scioto Intercepting Sewer (OSIS). These CSO structures are located at First Avenue, Third Avenue, King Avenue, Indianola Avenue, Frambes Street, Doe Alley, and Hudson Street.
- Prevent mainline Designed Sewer Relief (DSR) activations (up to 10-year peak flow recurrence) at DSR 156 & DSR 284 on the Franklin Main Interceptor, and DSR 873 on the Clinton Number 3 Trunk Sewer.
- Assist in mitigation of DSRs (up to 10-year peak flow recurrence) in designated Blueprint Columbus areas, including DSR 103 and DSR 107, and elimination of DSR 109 and DSR 111 in the Fifth by Northwest Blueprint area.
- Assist in mitigating Water-In-Basement (WIB) incidents (up to 10-year peak flow recurrence) in the Fifth by Northwest Blueprint area.
- Assist in mitigating chronic sanitary sewer manholes flooding (up to 10-year peak flow recurrence) in Tuttle Park.
LOT will connect into the upstream end of the previously constructed OSIS Augmentation Relief Sewer (OARS) at Vine Street. The upstream end of LOT will be located north of Lane Avenue where three existing sewers, the Franklin Main, the Olentangy Main and the OSIS are in close proximity to each other.
The design process for LOT began with identifying and evaluating potential alignments between these two end points and sampling geology in the area.
During design, the city evaluated six primary alignments and numerous variations. The primary factors evaluated were: hydraulic capacity, geologic characteristics of native soils and bedrock, groundwater, construction impacts, property acquisition requirements, alternative cost estimates, alternative schedules and a comparative risk evaluation.
See the selected alignment(PDF, 2MB)
The LOT main tunnel will require construction of approximately 17,000 feet of 12-foot diameter tunnel at an average depth of 50 feet. This portion will be mined with a tunnel boring machine (photo) and constructed of precast concrete segments. There are three main shafts (large manholes and other structures to provide access and tunnel controls) along LOT at Tuttle Park north of Lane Avenue, at Gowdy Field near Third Avenue & Olentangy River Road, and at Vine Street.
A 90-inch diameter microtunnel will also be constructed to relieve the OSIS near Second Avenue. The microtunnel will begin at the 2nd Avenue and Perry Street intersection and flow west into LOT at the Gowdy Field Shaft.
A 36-inch relief sewer will also be constructed to relieve a DSR in Third Avenue into LOT. This DSR is on the Kinnear Subtrunk Sewer which serves the Fifth by Northwest Blueprint area.
The LOT project was bid during the Summer of 2020. Construction began in early 2021 and be completed in September 2026.
Financing for the LOT project is being provided through a below market-rate loan through the Ohio EPA’s Water Pollution Control Loan Fund (WPCLF) Program.

Summary: This project will extend sanitary sewer service further into the Northern Pickaway Joint Economic Development District which is located just south of Rickenbacker International Airport. The project will be advertised for bid and the City will issue the construction Notice to Proceed in early 2021.
CIP
The City of Columbus will be constructing the Intermodal Sanitary Subtrunk Extension (ISSE) in order to extend sanitary sewer service further into the Northern Pickaway Joint Economic Development District which is located just south of Rickenbacker International Airport and other surrounding areas.
The ISSE is an extension of an existing 60-inch sewer that currently passes through the Village of Lockbourne and terminates at the Norfolk Southern Intermodal facility on S.R. 762. The project area begins along Thoroughbred Court, just east of S.R. 762 Street and extends easterly, generally following Rickenbacker Parkway until it crosses Airbase Road. View the map(PDF, 392KB) for a more detailed alignment layout.
The finished diameter for the Subtrunk will be 54-inches. It will be constructed of reinforced concrete pipe (RCP) with a wet-cast, integral high density polypropylene (HDPE) studded liner that is jacked into place behind a micro tunnel boring machine (MTBM) as it mines through the soil and overburden. Hydrogeological and geophysical studies were performed to select the best technology for tunnel construction and to ensure the MTBM is designed to operate in a manner that reduces impacts to nearby residents and wells. The tunnel will be constructed at an approximate depth of 30 feet below ground.
The project will be advertised for bid and the City will issue the construction Notice to Proceed in early 2021. While the MTBM is mining, intermediate shafts will be constructed to provide jacking and service locations during construction and ultimately future connection points as the service area develops. Overall, the entire project is due to be completed by early 2024. Traffic impacts are being mitigated through restricted hauling hours and designated hauling routes.
To finance the construction of this project, the City of Columbus will apply for a low interest loan from the Ohio Water Pollution Control Loan Fund (WPCLF). The city has requested similar funding for the Blacklick Creek Sanitary Interceptor Sewer and many other Capital Improvements Projects in the past.
The Ohio EPA is currently reviewing the project applications and we expect to be issued a Final Finding of No Significant Impact (FNSI) for the City of Columbus, Department of Public Utilities’ Intermodal Sanitary Subtrunk Extension project (WPCLF Loan Number CS390274-0379).

Summary: This project will rehabilitate existing sanitary sewer mains and manholes, reducing occurrences of water in basements and sewerage overflows to area streams and rivers. Construction is expected to begin in summer 2019.
CIP
The 2018 Annual Lining Contract continues the ongoing process of rehabilitating existing sanitary sewer mains and manholes within the City of Columbus. The sewer lining program is part of the division’s ongoing efforts to maintain the integrity of the city's sewer system, parts of which are up to 160 years old.
The sanitary infrastructure within Columbus includes miles of older sewers that have outlived their useful service lives, making them more prone to leaks and/or failures. Sewer lining has the added benefit of reducing the amount of inflow and infiltration of stormwater into the sanitary sewer system, thereby reducing occurrences of basement flooding and sewerage overflows to area streams and rivers. Rehabilitation candidates are identified by routine closed circuit television inspection.
This contract includes over 44,800 linear feet (approximately 8.5 miles) of 8-inch to 36-inch diameter sewers, and 260 manholes. The sewers are being be rehabilitated using cured-in-place pipe (CIPP) methods and the manholes will be rehabilitated with a cement liner. Work began in summer 2019 and will continue through 2021.
Residents within each rehabilitation area will receive a letter and a doorhanger prior to the work being performed. These notifications will give information on timing of the work, contact information, and a request to restrict water usage for 8-10 hours while the sewer main is being CIPP lined. Residents will then receive a final doorhanger indicating the work has been completed and that it’s safe to resume water usage.
Current plumbing codes require all plumbing fixtures to have approved traps which prevent sewer gases from entering the building. If you experience sewer odors in your house, you should first ensure that your plumbing traps are not dried out by pouring several cups of water down each fixture (sink, shower, floor drain, etc.). If odors persist, you may have a defective or missing trap and should consult a plumber regarding an appropriate correction. This may be the case in some older buildings constructed under previous codes. In addition to unpleasant odors, sewer gases can contain substances harmful to your health.
If you are a City of Columbus resident and are experiencing sewer odors in your neighborhood, contact the city's Odor Complaint Hotline at 614-645-7961.
Financing for this project is being provided by the Ohio Environmental Protection Agency through its Water Pollution Control Loan Fund, a below market-rate loan program.

Summary: The Olentangy Augmentation Relief Sewer (OARS) tunnel will carry wet weather overflows that would otherwise empty into the Scioto River, to wastewater treatment plants. Construction began in September 2010 and is expected to be operational by late summer 2017.
CIP
A crucial requirement of the 2004 consent order between the City of Columbus and the State of Ohio is to reduce the environmental impacts caused by Combined Sewer Overflows (CSOs). The Olentangy-Scioto-Interceptor-Sewer) Augmentation Relief Sewer, known as OARS, is the key component in meeting this goal. This sewer tunnel will intercept wet weather overflows that currently empty into the Scioto River and carry the flows instead to the city’s Jackson Pike and Southerly wastewater treatment plants.
The tunnel will provide relief to the existing OSIS trunk sewer from just north of the Arena District to the Jackson Pike facility. The construction of Phase 1 began in September 2010 and involved digging a 20-foot diameter tunnel with a total length of about 23,300 feet. Phase 2 began in August 2011 and involves construction of three shafts, a pump station, pump electrical building, river overflow structure and other infrastructure. The overall project is currently scheduled to be completed in late summer 2017.
The overall length of the OARS tunnel is just under four and a half miles, and will include three relief structures that will divert wet weather combined sewer flow from the OSIS to the OARS tunnel. The OARS project will control all of the regulators (relief structures where the sewers currently overflow to the river multiple times per year) in the downtown riverfront area to a level in which they might overflow once every ten years on average.
The tunnel is being built approximately 170 feet below ground, reducing risks associated with construction at more shallow levels. This will require special drop structures (or vertical shafts) to direct flow from existing shallow sewers to the new deep tunnel. In addition, the drop structures will dissipate energy and minimize air entry into the tunnel. The tunnel shafts are designed to handle hydraulic surges which will prevent impacts on upstream sewers.
This project is the largest capital improvement project undertaken by the City of Columbus to date. Total construction cost is just under $371,000,000 with an additional 5,661,608 spent on downtown odor reduction facilities. Financing for the project is through low interest loan funds available from the Ohio EPA and the debt is serviced through Columbus sewer customer revenue.

This sewer rehabilitation project, off of Nelson Road, utilized a trenchless technology known as cured-in-place-pipe (CIPP). Instead of an open cut excavation from the surface to repair or replace the sewer, CIPP works by inserting a resin-saturated felt liner into the existing sewer, which is rehabilitated when the resin liner is cured to a hard finish. The process and equipment used to create this “pipe within a pipe” varies by the diameter of the sewer line; access to the sewer is typically gained through manholes.
This rehabilitation method is not always an option for a variety of reasons, such as size and condition of the sewer line. When this technique can be used, it can offer many benefits compared to traditional trenching replacement methods, including:
- Less disruption to residents, businesses and motorists;
- Reduced construction time; and
- Reduced loss of trees.
The trenchless relining method reinforces the structural integrity of the sewer line, seals leaks, and extends the life of the sewer by 50-100 years. The City of Columbus has used CIPP on deteriorating sewers throughout the city.
Current plumbing codes require all plumbing fixtures to have approved traps which prevent sewer gases from entering the building. If you experience sewer odors in your house, you should first ensure that your plumbing traps are not dried out by pouring several cups of water down each fixture (sink, shower, floor drain, etc.).
