Water & energy

Water and energy: establish the cost of an industrial use

The purchase price per cubic metre does not describe the cost of water pumped, treated, heated and discharged. A method to prepare the comparison.

Follow the water through the plant

Purchased water may be filtered, pumped, heated and used for cleaning before reaching discharge treatment. Each stage may add cost. To compare actions, we describe the path of the stream and the equipment it uses.

Calculation boundaries are explicit: water purchasing, treatment, energy, chemicals, maintenance and discharge, depending on available information. A cost already included in a tariff must not be counted twice. Fixed charges are separated from expenses that vary with volume.

Build a comparison that can be checked

For a cost proportional to volume, the estimate starts with avoidable volume over a defined period, multiplied by the relevant variable unit cost. Tariffs, operating hours and assumptions are kept with the calculation. Energy consumption comes from measurements or an estimate explicitly identified as such.

Water recovery may reduce purchases while adding pumping, consumables or cleaning. Those new expenses enter the same balance. Estimated net savings depend on future operation and must not be presented as already measured savings.

Plan measurement after the work

Before an intervention, we define the meters, reference period and production data needed for the comparison. Results need to be related to output, production mix and operating conditions.

Vanguard Waters combines the water balance with energy expertise from Vanguard Systems. The aim is to connect maintenance, adjustment or investment decisions with indicators the teams can track after commissioning.
