body
PURPOSE:
To obtain City Council approval to award a contract to Era Valdivia Contractors, Inc., Chicago, IL, (EVC) for the Indian Trail Elevated Tank Rehabilitation Improvements for the Water Production Division (WPD) in an amount of $1,399,250.00.
BACKGROUND:
The 1.5 million gallon Indian Trail Elevated Tank, located at 1325 West Indian Trail, provides potable water distribution system pressure and storage capacity.
