Title

2017 and 2018 Sanitary Sewer Smoke Testing and Manhole Inspection Program - Proposal

 

History

The Metropolitan Water Reclamation District of Greater Chicago (MWRD) governs over the sanitary sewer system of the village. The MWRD requires sanitary sewer systems that discharge into the MWRD facilities to implement measures to reduce excessive Infiltration and Inflow (I&I) from entering MWRD’s system. 

 

In 2015, the village selected RJN Group as the Comprehensive Sanitary Sewer Evaluation consultant to provide assistance in developing and implementing a Village-wide comprehensive sanitary sewer evaluation & repair program in order to meet the MWRD requirements for the Inflow and Infiltration Control Program (IICP). 

 

RJN Group conducted comprehensive flow monitoring for the Village sanitary sewer system in 2016. Based on those results, three sewer basin areas came up as the highest priority. One of these basins was also identified as the Short-Term High Priority Area identified and submitted to the MWRD for the new Inflow and Infiltration Control Program (IICP). Smoke testing, manhole inspections, closed circuit television inspection and rehabilitation for “High Priority” defects found in this critical area are mandatory under the new MWRD IICP program.  The Village requested a proposal from RJN Group to perform the required inspections and testing.  Public Works staff is interested in conducting the first half of the manhole inspections for this basin in 2017 and conducting the remainder of the smoke testing and manhole inspections in the MWRD high priority basin in 2018. The total work includes approximately 470 manhole inspections and 91,700 LF of smoke testing in 2017 and 2018.

 

The estimated cost for performing the required testing and inspections per the proposal from RJN Group is $129,195.00. Staff is recommending a contingency for unexpected sanitary sewer encounters for the project in the amount of $10,000.00.

 

On August 7, 2017, this item was reviewed by the Public Works Committee and recommended for approval and referred to the Village Board of Trustees for consideration.

 

Financial Impact

Funds to complete this project are included in the FY17 Water and Sewer budget, account 031-6003-470500.

 

Recommended Action/Motion

I move to approve accepting the proposal for 2017 and 2018 Sanitary Sewer Smoke Testing and Manhole Inspection Program from RJN Group of Wheaton, Illinois, for an amount not to exceed $139,195.00 ($129,195.00 plus $10,000 contingency).
