Award of Professional Services Agreement for the Southeast Joliet Sanitary District Water Source Transfer Assistance to Engineering Enterprises Inc. for a Not-to-Exceed Amount of $487,500.00
end
BACKGROUND:
The City of Joliet is preparing for acquisition of the Southeast Joliet Sanitary District (District) water and sanitary sewer systems. The transfer of ownership of the District's water and sanitary sewer systems will be accomplished via an intergovernmental agreement with Will County (County) and the District. The County will be providing funding via multiple sources to fund improvements in the District system.
One of the improvements being funded by the County is the transfer of the District's shallow aquifer water source to the City's deep aquifer water source. Before the City can transfer water sources it must prepare a water transition plan per the requirements of the Illinois Environmental Protection Agency (IEPA). The city anticipates IEPA will require a demonstrative study be performed to ensure the transition will not cause a release of lead or other contaminates into the water. A new interconnect between the systems will also need to be designed and constructed.
The Public Service Committee will review this matter.
CONCLUSION:
The City contacted Engineering Enterprises Inc. (EEI) to assist with the required tasks. EEI will partner with Cornwell Engineering Group to complete the following engineering services for an amount not-to-exceed $487,500.00: preparation of the water system transition plan, completion of an Optimal Corrosion Control Treatment study, water modeling, preparation of design documents for the water system interconnect, and development of a pilot protocol for a demonstrative study.
EEI and Cornwell have teamed together to provide similar services for the City previously and are the most qualified to perform this work.
