Union Sanitary District continues repairs

Submitted By Michelle Powell

Crews repairing damage caused by an October 14 sinkhole in Union City were able to complete another element of the project and reopen an additional lane of traffic.

The sinkhole caused extensive damage to a sewer pipe that runs 20 feet below Alvarado Boulevard in Union City. A manhole in the area also was damaged when the sinkhole occurred. The repair project has required closing some traffic lanes on Alvarado Boulevard between Fair Ranch Road and New Haven Street.

On November 3, Union Sanitary District (USD) crews completed installing an underground bypass pipe needed to ensure sewer service is not interrupted during the repair project. This allowed them to remove temporary, street-level bypass lines that had occupied one traffic lane of Alvarado Boulevard.

Both eastbound lanes and one westbound lane now are open. One westbound lane of the boulevard will remain closed until the project is completed.

A repair to the sewer pipe will begin once USD is able to assess the extent of the damage and select the best repair method. This assessment has been hampered by difficult soil conditions and high groundwater levels in the affected area.

The cause of the sinkhole is still unknown at this time. ÒThis is going to be a project that will require patience on the part of everyone involved,Ó said USD General Manager Paul Eldredge. ÒThere is a great deal of work to be done, and we are determined to do it as safely and quickly as possible.Ó
