SUBJECT:
A Resolution Awarding the 2019 Small Diameter Sanitary Sewer CIPP Lining contract to Visu-Sewer of Illinois, LLC, 9014 S. Thomas Ave, Bridgeview, IL 60455.
PURPOSE:
The City of Aurora Engineering Division has identified sewer repairs that can be addressed with cured in place pipe lining.
BACKGROUND:
Televising a portion of the City's sewers is the first part of the annual sewer maintenance program conducted by the City. Each year, sewers are cleaned and televised if they are known to have potential issues or are under roadways that will be rehabilitated in the near future. This televising provides useful information to the Engineering and Water & Sewer Divisions that cannot be seen when inspecting sewers from within manholes or other entry points. While reviewing the televising results, issues are identified and the proper solution is designed and implemented. Repair of the sewers with trenchless methods such as cured in place pipe lining (CIPP) are preferred due to the cost savings and minimal impacts to residents. The sewers included in this contracted have been identified in the past two years as having deficiencies with severity ratings of either 4 or 5 with 5 being the worst rating possible. If these deficiencies are not lined in the near future, the conditions will worsen and a dig repair will be required which is much costlier than lining the deficiency. A location map showing the various sewer locations to be lined is attached as Exhibit A.

Visu-Sewer of Illinois, LLC's bid of five hundred sixty-four thousand, eight hundred and fifty-eight dollars and ninety-five cents ($564,858.95) was the lowest responsible bid of four (4) bids received.
