TO: Mayor Richard C Irvin
FROM: Michael Houston Assistant Superintendent of Water and Sewer Maintenance
DATE: April 11, 2023
SUBJECT:
Replace a 2004 Combination Sewer Cleaning Machine with a VAC-CON Model V312HE/1300 LA Combination Sewer Cleaning Machine from EJ Equipment of Manteno Illinois in the amount of $563,662.00
PURPOSE:
The purchase of a new combination sewer cleaning machine is needed in order to help ensure that the City of Aurora meets its Environmental Protection Agency National Pollutant Discharge Elimination System (EPA NPDES) permit requirements and to minimize sewage basement backups and street flooding.
BACKGROUND:
The US and Illinois EPA expect municipalities like the City of Aurora to proactively maintain their sewer systems in order to avoid sanitary sewer overflows (SSO's) and minimize pollutants in storm water runoff . SSO's result in raw sewage discharges into the Fox River and other streams as well as basement sewage backups. SSO's are often caused by blockages in publicly owned sewers that could be avoided through regular sewer cleaning.
The City of Aurora's Water and Sewer Maintenance Division is responsible for cleaning approximately 1,200 miles of sanitary, combined and storm sewers as well as approximately 16,000 manholes and over 30,000 catch basins. Catch basins are storm inlets designed to protect sewer pipes by trapping debris in sumps. For catch basins to perform properly and avoid street flooding they need to be cleaned on a regular basis. The existing 2004 Sewer Cleaning Machine is inoperable and beyond its useful life span.
DISCUSSION:
Water and Sewer Maintenance is recommending that the City of Aurora purchase the VAC-CON sewer cleaning machine from EJ Equipment using the Sourcewell Cooperative Purchasing Agreement contract number 101221-VAC in the amount of $563,662.00 after the trade in of an existing 2004 VAC-CON in the amount of $20,000. Funding for this purchase includes $457,500.00 in account number 510-...
