Development of Chemical Precipitation Purchased Equipment 

Costs:

Tanks

Purchased Equipment Costs are the sum of the following cost elements:

(1) Pump Costs

(2) Tank Costs

(3) Chemical Feed System Costs

(4) Mixer Costs

(5) Clarifier Costs

(6) Filter Press Costs

(7) Sand Filter Costs

Each cost component includes the cost of freight and associated ancillary equipment such as piping, valves, and 

controllers.

The following telecons support EPA’s development of cost element (2) by providing purchase costs and 

information regarding FRP tanks used in the Steam Electric cost model.

GENERAL SUBJECT: Vendor cost request for tanks for a chemical precipitation wastewater treatment system.

TOPICS DISCUSSED AND ACTION TAKEN

On Monday, March 21, 2011 at 4:00 pm I contacted Augusta Fiberglass to obtain costs for tanks needed for 

chemical precipitation wastewater treatment systems for FGD wastewater. I was directed to Mr. David Reuis. I 

explained to Mr. Reuis that we are working on conceptual level costing of a chemical precipitation wastewater 

treatment system to treat FGD (flue gas desulfurization) wastewater from steam electric power plants and as a 

part of this project, we are trying to collect cost information on different components or units of a chemical 

precipitation system. Mr. Reuis indicated that they had provided tanks for FGD wastewater treatment before.

I told Mr. Reuis that we would like to get purchase costs including ancillary equipment such as structural 

supports and access walkways for multiple tanks. I told him that we had limited information including flow 

rates and approximate residence times for most of the tanks, as well as some additional information on the use 

of the tank (e.g., lime would be added to reaction tank 1). For some of the tanks, I told him we would like his 

opinion on the tank needed and the costs. He stated that as much information as we could provide would be 

helpful for him to provide costs, however, they can estimate costs based on the flow rates and residence times.

I asked Mr. Reuis if there are any power requirements for tanks. He said that if any temperature regulation (i.e., 

insulation, heating) is needed there may be power requirements. I also asked if they could provide costs for 

chemical storage tanks. He said they can do this and useful information would be the size of the tank, the 

chemical stored, the percentage of the chemical and the temperature. He also stated that based on the 

wastewater tanks chemical is added to, they can estimate the size of chemical storage tank needed. I also asked 

Mr. Reuis if they could provide costs for mixers. Mr. Reuis stated that they could provide costs for mixers but 

when mixers are provided with the tanks, Augusta Fiberglass obtains them from another vendor and charges a 

premium on the mixer cost. He stated it is cheaper for a client to go to a mixer vendor directly.

Mr. Reuis asked for the request via email and stated he could provide the information within a few days.

GENERAL SUBJECT: Vendor cost request for tanks for a chemical precipitation wastewater treatment system.

TOPICS DISCUSSED AND ACTION TAKEN

Mr. Michael Hawkins left me a voicemail in response to my call with Mr. Reuis. On Friday, April 1, 2011 at 

10:45 am I contacted Mr. Hawkins to obtain costs for tanks needed for chemical precipitation wastewater 

treatment systems for FGD wastewater.

Mr. Hawkins stated that typically shop-built, field-erected tanks range from 10,000 gallons to 50,000 gallons in 

size and would cost approximately $1.25/gallon to purchase. Field-erected tanks range from 50,000 gallons to 

250,000 gallons in size and would cost approximately $2.00/gallon to purchase. He said to account for ancillary 

equipment, such as nozzles and baffles, the cost could be escalated 15%. Mr. Hawkins also stated that the 

largest tank (250,000 gallons) would have a diameter of 42 feet and height of 25 feet. The tank size is limited by 

shipping constraints, such as low overpasses, particularly on the East Coast. Tanks larger than this size would 

need to be field-erected and built which would require a build shop on site, increasing the expense.

Mr. Hawkins stated that typically, ancillary equipment provided with the tank includes a mixer bridge, hold 

down lugs, manways, bolts and gasket for manways, spare nozzles, and level connectors. Ancillary equipment 

that may be required but is not included in the purchase cost includes shut off valves, outlet pumps, and external 

piping.
