About this file
This is a cost calculation exhibit for circulating cooling water treatment services prepared for the City of Pasadena Water & Power Department's Glenarm Power Plant located in Pasadena, California. The exhibit establishes a standardized framework for bidders to calculate annual chemical treatment costs based on four primary chemical categories: scale inhibitor, corrosion inhibitor, oxidizing biocide, and non-oxidizing biocide. Bidders are required to specify their recommended number of concentrations (minimum of two, maximum of one, with an average used for calculations), identify the generic type and product name/number for each chemical, provide the required dosage rates in parts per million or pounds per year, and submit unit costs per pound of chemical. The form requires bidders to calculate annual costs for each chemical category, with oxidizing biocide dosage set at 150 pounds per year and non-oxidizing biocide applications occurring 50 times annually during summer months.
The pricing structure incorporates blowdown costs associated with scale and corrosion inhibitors, calculated per million pounds of blowdown water. Bidders must project total annual blowdown volumes and calculate the combined annual chemical cost by multiplying the blowdown rate by the total cost per million pounds of blowdown. The final deliverable is a total circulating cooling water treatment annual cost, calculated by summing annual expenses for chemical blowdown, oxidizing biocide, and non-oxidizing biocide. The exhibit also requires bidders to specify complete product specifications for each of the four chemical categories, providing transparent pricing visibility for the Water & Power Department's evaluation of qualified chemical consultant proposals.
