Note from TheGardeningSnail: this page may have been produced by running a PDF Image File through a program that converts Image to Text. My apologies to any textual gremlins that may have crept in. I have also added a map, so you can see the location of the well involved: since most of the water used at that well goes to Foster Farms. I have also broken up some of the longer Paragraphs to make reading easier.

AGENDA ITEM: Resolution Awarding the Replacement of GAC Media at Well #8. MEETING DATE: April 5, 2016
PREPARED BY: Alfonso Manrique, Alternate City Engineer
REVIEWED BY: Odi Ortiz, Interim City Manager
That the City Council adopt Resolution No. 2016-_, a resolution awarding the replacement of GAC Media at Well #8 to Calgon Carbon Corporation and Evoqua.
BACKGROUND AND DISCUSSION:
The City of Livingston owns and operates a TCP removal treatment plant at Well #8. The GAC treatment plan utilizes Granular Activated Carbon (GAC) Technology. GAC technology uses an absorptive media (GAC) to remove contaminants from the water. GAC media loses its absorption capacity overtime and it eventually needs to be replaced.
The GAC media in the vessels has not been replaced since the treatment system was commissioned in early 2014. The original media supplies with the vessels were expected to treat approximately 265 MG of water (55,000 Bed Volumes). Routine monthly sampling of the water quality at Well #8 indicates that the media life may be longer than originally anticipated
The volume of water treated through the system as of February 2016 is nearing 80 percent of the projected capacity and provisions must be made to replace the GAC media with new virgin media.
The City solicited bids from GAC media suppliers to replace the media at Well #8. Two suppliers responded to the City’s solicitation: Calgon Carbon Corporation and Evoqua. Each bidder proposed on a different GAC media. Calgon Carbon proposed a bituminous coal media and Evoqua proposed a coconut shell media. Both medias have been tested and compared in numerous studies and their performance varies by installation.
Staff recommends that the City splits the award of the contract into two packages. Package No. 1 to the Calgon Carbon Corporation (low bidder) to remove and reactivate the existing media and to furnish and install new virgin GAC media in two of the vessels (40,000 lbs approximately).
Package No. 2 to Evoqua to furnish and install new virgin media in the other two vessels (40,000 lbs approximately). Installing two different medias will provide the City full scale comparison of their performance. The comparison will provide very valuable information to future media selection for other treatment plants in the City.
The contract documents used in the solicitation of bids provided the option of splitting the contract as described above.
The award of the contract has an overall fiscal impact of $212,756.00. The Fiscal impact on this
FY 2015/16 budget will only be $135,956.00. The City had budgeted $200,000 in this FY 2015/16 for the replacement of media at Well #8 and Well #16. The media at Well #16 appears to be performing better than expected and does not need to be replaced at this time.
