Project Overview

Environmental Services is designing a project to repair about 3,700 feet of the 110-year-old brick Taggart Outfall sewer so that it can operate for another hundred years. The sewer pipes are showing signs of cracks, fractures, missing brick and mortar, and obstructions in the pipe, putting the Outfall at risk of structural failure. This project will allow the Taggart Outfall sewer to properly perform its role in protecting public health, water quality and the environment.

The Taggart Outfall is a large-diameter and deep sewer pipe. It is between 5 to 10 feet wide and 23 to 64 feet below the surface. Safety requires that crews will only be able to work in the Outfall pipes on days when there will be no flow from either rain or other parts of the sewer system.

Schedule

Construction of the Taggart Outfall Sewer Repair Project is anticipated to begin in summer 2018 and take approximately six to eight months to complete. Because crews can work in the Outfall pipes only when the weather is dry, completion may require nighttime work or a second construction season in summer 2019.
