 APPROVED BY CITY ADMINISTRATOR: Michael L. Guttman            SIGNATURE

 As part of the City's water treatment process, rotary hydrated lime is used to purify the raw water through
 a softening process. When the lime bonds with targeted minerals (i.e., radium, calcium, magnesium,
 etc.) sludge is generated. The sludge is transferred to three exterior holding lagoons until contractually
 removed. Typically, the removal takes place on a bi-annual basis and the waste is taken to a landfill. The
 last such project was completed in late 2020.

 Based on the lab results, the City's lime sludge meets the criteria for land application. Plans and bid
 specifications were prepared in house for a land application. This project was advertised in the Daily
 Herald and on QuestCDN an online bidding platform on July 5 with a bid opening on July 26. At that time,
 the City didn't receive any bids.

 This project was re-advertised in the Daily Herald and on QuestCDN (an online bidding platform) on
 August 2 with a bid opening on August 19. The plans were adjusted to have a base bid of landfill
 application with an alternate to perform land application as well as a combination of landfill and land
 application. The City received only one bid. The bid results are shown below.

  Engineer's Estimate      $880,000.00           N/A                  N/A


 The City has budgeted $880,000.00 in the 2022 Budge under account 06-34-48-4210.

 Staff recommends rejecting this bid and seeking alternate means and methods of removing and
 disposing of the waste lime sludge. Staff will be working closely with industry professionals to determine
 the best and most cost efficient methods of disposal.  Staff will return to the Infrastructure Committee
 with updated options.
