Engineering planning checklist

Water Utility Pump Station & Energy Audit

Audit process-water demand, calculate water-pipe velocity and friction loss, determine planning-level TDH and hydraulic duty, and estimate annual pumping energy cost.

Use as a checklist, not an automated design workflow. Complete and verify each calculation independently. Only explicit carry-forward links move a compatible value; all other inputs remain your responsibility.

What this workflow covers

Audit process-water demand, calculate water-pipe velocity and friction loss, determine planning-level TDH and hydraulic duty, and estimate annual pumping energy cost.

This 7-step checklist is intended for plant operations manager. Confirm each linked calculator's units, formula, assumptions and operating limits before using the result in a project decision.

Sequence Execution
1

Plant Water Balance Calculator

Determine total plant water requirement, recycled water return from thickeners/tailings dam, and fresh makeup water intake.

WORKFLOW INSTRUCTION:Quantify process demand and recycled water before selecting a transfer duty.
2

Pipe Velocity & Diameter Sizing

Size pipe internal diameter or calculate fluid velocity based on volumetric flow rate.

WORKFLOW INSTRUCTION:Check the proposed water flow and pipe internal diameter against the resulting velocity.
3

Reynolds Number Calculator

Determine flow regime (Laminar, Transition, Turbulent) in circular pipes.

WORKFLOW INSTRUCTION:Confirm the water-flow regime and record the density and viscosity assumptions used for the loss estimate.
4

Pipe Pressure Loss Calculator

Scope-limited calculation

Calculate water head loss and friction pressure drop in straight pipe runs using the Darcy-Weisbach equation. This screen is water-only; do not use it for slurry or compressible-gas service.

WORKFLOW INSTRUCTION:Estimate straight-run water friction loss with the published Darcy–Weisbach assumptions, then add fittings and equipment losses separately.
5

Static & Total Dynamic Head (TDH)

Calculate Total Dynamic Head required for pump selection from static lift, friction loss, and discharge pressure.

WORKFLOW INSTRUCTION:Combine static elevation, discharge pressure, and friction losses into planning-level total dynamic head.
6

Pump Hydraulic Power Calculator

Calculate fluid hydraulic power (absorbed power) delivered to liquid by a centrifugal or positive displacement pump.

WORKFLOW INSTRUCTION:Calculate the ideal hydraulic duty from water flow, head, and specific gravity before applying pump and driver losses.
7

Pump Operating Energy Cost Calculator

Scope-limited calculation

Calculate annual electrical energy consumption (kWh) and operating cost ($/year) for pumping systems.

WORKFLOW INSTRUCTION:Estimate annual pumping kWh and cost from absorbed motor power, operating hours, and tariff; verify the duty cycle and tariff structure.
