ITEM  38 City Council Memorandum      Public Works & Utilities  Memo No. UA25-012         Date: October 14, 2024 To: Mayor and Council Thru: Joshua H. Wright, City Manager Andy Bass, Deputy City Manager John Knudson, Public Works and Utilities Director From: Christian Jonson, Procurement Officer Subject: Agreement No. WW0-885-4192, Amendment No. 4, with Carbon Activated Corporation, for Activated Carbon

Proposed Motion:

Move City Council approve Agreement No. WW0-885-4192, Amendment No. 4, with Carbon Activated Corporation, for activated carbon, in an amount not to exceed $960,000, for a one-year period, October 1, 2024, through September 30, 2025.

Background/Discussion:

Activated Carbon (AC) is a granular carbon material used in odor control systems at the city's wastewater treatment facilities to absorb hydrogen sulfide gas (H2S) produced in the wastewater collection system. AC used in the wastewater odor control systems has a limited lifespan and deteriorates during use. The effectiveness of the carbon in the odor scrubbers at the city's facilities is nearing the end of its useful life. Replacement of the AC is expected twice per year, at a minimum. AC is also added at the beginning of the water treatment process at the Pecos Surface Water Treatment Plant (PSWTP) to help remove organic material which may cause undesired taste or odor in drinking water while also helping reduce trihalomethane (THM) precursors throughout the treatment process to improve water quality. Because the PSWTP uses AC as a direct additive to the treatment process, new product needs to be continuously ordered and applied. This agreement will allow city staff to purchase AC products for use in drinking water treatment and water reclamation facility odor mitigation.

Evaluation:

On July 16, 2020, City Council approved an agreement with Carbon Activated Corporation, for activated carbon, for a one-year period, with the option of up to four one-year extensions. The contractor has agreed to extend for one year, October 1, 2024, through September 30, 2025. This is the fourth extension of the original agreement.  The previous agreement was for $2,450,000.  This large reduction in cost is due to the city executing a request for proposal (RFP) for powdered activated carbon.  Powdered activated carbon has historically been purchased through this agreement, but will now be purchased through a new agreement once it is awarded.
