This unit model is formulated as a single-input, double-output model form. See documentation for :ref:`single-input, double-output Helper Methods<sido_methods>`.
Electricity consumption is calculated using the pump_electricity helper function. See documentation for :ref:`Helper Methods for Electricity Demand<electricity_methods>`.
Costing is calculated using the cost_ion_exchange method in the zero-order costing package. See documentation for the :ref:`zero-order costing package<zero_order_costing>`.
