South Shore 2022 Wastewater System Rehabilitation
This project involves rehabilitating deteriorated components of the wastewater (sewer) system. The City has identified pipelines and manholes having high rates of unwanted surface and groundwater, or where the pipelines and manholes are experiencing structural failure in the form of cracks, separated joints, or partial collapse. These were identified during the South Shore Sewer Study Program conducted a few years ago, as part of the City's Wastewater System Master Plan.
Project Goal
The main project goal is to reduce rain (surface water) and groundwater infiltration into the wastewater system (known as inflow and infiltration or I&I). As wastewater pipes age, they leak more, allowing rain and groundwater to enter the system and mix with the wastewater. There are also places where drains from roofs or parking lots allow rainwater directly into the wastewater pipes. The problem with I&I is that when clean rain or groundwater get into the wastewater system, it takes up capacity that could be used for dirty sewer water. We don’t want to pay to build bigger pipes when a much cheaper alternative is to keep clean water out of the wastewater system.
Project Need
Replacement or rehabilitation of the South Shore Basin wastewater system will extend the service life of the wastewater system and provide additional maintenance access via property line cleanouts. Additionally, reduction of I/I entering the wastewater system reduces the treatment volume reaching the Tryon Creek Wastewater Treatment plant.
Scope of Work
The project will involve the rehabilitation of public mainlines and public laterals and, reconnection of each homeowner’s service laterals to the ends of the public laterals or mainlines.
The project was separated into two contracts: pipe replacement and pipe lining. Pipe replacement was completed in April 2022. The pipe lining scope includes approximately 4,000 linear feet of wastewater pipe lining, the rehabilitation of approximately 80 wastewater manholes, and nearly 40 lateral connections.
For the pipe lining, work will take place on portions of the following streets:
- Carlson Court
- Greentree Road
- Greentree Circle
- Weidman Ct
- Robb Place
- Sunny Hill Drive
- Cherry Crest Drive
- South Shore Blvd
- Kilkenny Road
- Lowenberg Terr
- Laburnum Way
Schedule
Pipe lining work is expected to begin in mid-late July and continue through late summer 2022. Schedules are subject to change.
July 2022
Preliminary pipe lining work is expected to begin in mid-late July and continue through August. Neighbors may notice survey stakes and locate marks for utilities, along with equipment mobilizing to nearby streets. Crews expect to begin working on lining the wastewater pipes on each street for a few days in early August, followed by repairing manholes and general clean up.
What to expect:
- Work hours are Monday to Friday, 7 a.m. – 6 p.m.
- Intermittent lane closures will be in place with flaggers directing traffic. Please expect some delays during work hours.
- Access will be maintained throughout construction; however, at times some on-street parking will be limited.
- Some residents may experience temporary sewer service interruptions for short periods while connection work is being done. In these instances, notification will be provided at least the day prior.
- Equipment and materials will be stored in the public right-of-way (during and after work hours) and within work zones.
- Construction can be loud, dusty, and cause traffic delays. Working equipment includes truck traffic, vactor trucks, excavators, compactors, steel plates and other heavy equipment.
Schedules are subject to change.

Sewer Pipe Replacement Project Contract bids opened and awarded to Icon Construction, LLC
May 10, 2021
The City has postposed this sanitary sewer rehabilitation project. During the bidding process the City received one bid, which exceeded the engineer's estimate. As a result, it was decided that it was not in the City's best interest to proceed with the project at this time. City staff are re-evaluating scope and specifications with the intent to re-bid the project in the fall of 2021.
March 31, 2021
The South Shore Rehabilitation Project is currently in out to bid. The City anticipates awarding the contract for construction in May of 2021. Construction is expected to begin in summer 2021 and conclude in fall 2021.
