Development of Chemical Precipitation Purchased Equipment Costs:

Pumps

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

This Excel workbook consists of the following worksheets:

WW Forwarding

Treated Eff Discharge

Sump

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

controllers.

Each worksheet in this workbook derives an equation relating FGD Wastewater Flow, gpm to the cost of each required 

type of pump. FGD Wastewater Flow, Pump Cost, and Pump Weight were obtained from Weir Mineral's cost proposals 

(DCNs SE01825.A3-A6) and Freight Costs were approximated from FreightCenter.com's online cost estimator (DCN 

SE01825.A7) using Pump Weight. Pump Cost was plotted against FGD Wastewater Flow and a trendline was added to 

relate the two. Freight Cost was then divided by the Pump Cost to develop the Freight Cost/ Pump Cost Ratio. The cost 

ratio is consistently between 3 and 5%; therefore, EPA assumed a Pump Freight Factor of 4%.

This Excel workbook documents EPA's derivation of cost element (1) using information provided in response to the Steam 

Electric Survey and industry vendors.

EPA determined total pump costs for each plant using the plant's FGD Wastewater Flow, gpm in the equations derived in 

this workbook, the quantity of pumps required, the capacity factor, and the Pump Freight Factor developed in this 

workbook.

FGD Wastewater Flow, Pump Cost, and Pump Weight were obtained from Weir Mineral's 

Wastewater Forwarding Pump proposal (DCNs SE01825.A3) and Freight Costs were 

approximated from FreightCenter.com's online cost estimator (DCN SE01825.A7) using 

Pump Weight. Wastewater forwarding pumps and FGD recycle pumps are costed based on 

the same data.

FGD Wastewater Flow, Pump Cost, and Pump Weight were obtained from Weir Mineral's 

Treated Wastewater Discharge Pump proposal (DCNs SE01825.A4) and Freight Costs were 

approximated from FreightCenter.com's online cost estimator (DCN SE01825.A7) using 

Pump Weight.

FGD Wastewater Flow, Pump Cost, and Pump Weight were obtained from Weir Mineral's 

Sump Pump proposal (DCNs SE01825.A5) and Freight Costs were approximated from 

FreightCenter.com's online cost estimator (DCN SE01825.A7) using Pump Weight.

Pump proposal (DCNs SE01825.A6) and Freight Costs were approximated from 

FreightCenter.com's online cost estimator (DCN SE01825.A7) using Pump Weight. While 

lime slurry pumps are not costed, the lime slurry pump equations are used to cost sludge 

recycle/transfer pumps. To calculate slurry flow (or sludge flow) for each plant, sludge factor 

was applied to the plant's FGD Wastewater Flow.
