RECOMMENDATION:

That the City Council adopt Resolution No. 2016-_, a resolution awarding the supply of up to ten (10) GAC Adsorption Systems for TCP Removal to Loprest Water Treatment Company.

BACKGROUND AND DISCUSSION:

The City of Livingston’s water supply wells produce water that contains 1,2,3-Trichloropropane (TCP). TCP is a manmade chemical found at industrial or hazardous waste sites. It has been used as a cleaning and degreasing solvent and also is associated with pesticide products. TCP causes cancer in laboratory animals and it is reasonably anticipated to be a human carcinogen as well.

TCP is currently unregulated but new SWRCB regulations are expected to go into effect in Spring or Summer of 2017. The recommended MCL for TCP is expected to be at 5 parts per trillion (ppt). TCP concentrations in the groundwater produced by the City’s wells range from 20 ppt to 780 ppt. Therefore, if the recommended limit is adopted, all of the City’s wells will require treatment in the future.

TCP is usually removed from the groundwater using Granular Activated Carbon (GAC). GAC technology uses an absorptive media (GAC) to remove contaminants from the water. Well #8 was the first of the City’s wells to have a GAC Adsorption System to remove TCP. In anticipation of the upcoming regulations, staff recommends to begin the planning and design process for the rest of the treatment systems at the City’s wells. The first step consists of pre-selecting an equipment manufacturer to supply the GAC Adsorption Systems that will be needed.

The City solicited bids from equipment manufacturers to supply up to ten (10) GAC Adsorption Systems. Four (4) suppliers responded to the City’s solicitation: Calgon Carbon Corporation, Evoqua Water Technologies, Loprest Water Treatment Company, and Westech Engineering. The following table summarizes the bid amounts from each bidder.

Bidder

Bid Amount

Calgon Carbon Corporation

$2,371,000.00

Evoqua Water Technologies

$2,250,000.00

Loprest Water Treatment Company

$2,165,000.00

Westech Engineering

$2,246,205.00

After the review of the bid packages, Staff finds that the lowest responsive bidder is Loprest Water Treatment Company. Loprest Water Treatment Company is also the supplier of the filtration equipment at Well #13 and Well #17. Staff recommends that the City awards the supply of the GAC Adsorption Systems to Loprest Water Treatment Company.

FISCAL IMPACT:

The award of the contract has an overall fiscal impact of $2,165.000.00. The fiscal impact will be spread over the next three fiscal years. The City will order the GAC Adsorption Systems as needed. Staff recommends that City applies for construction funding from the Drinking Water State Resolving Fund for the purchase and construction of the TCP removal treatment systems. The TCP fund will then be reserved for on-going operations and maintenance cost.
