Water Lifecycle Costs in EnergyPlus

I was wondering if anyone has experience adding lifecycle costs to EnergyPlus for water consumption.

I was able to add water costs as a fuel using UtilityCost:Tariff object, but in that scenario it shows up under "Energy" instead of "Water" on the "Operating Cash Flow by Category (Witihout Escalation) " table which isn't ideal. Has anyone taken a different approach where they were able to populate the "Water" column?

Here is the table in question.

Here is the EnergyTable which feeds into the "Energy" column above. Notice that it does include water costs. image description

And here is my Tariff object.

UtilityCost:Tariff,
  Water Tariff,                           !- Name
  Water:Facility,                         !- Output Meter Name
  UserDefined,                            !- Conversion Factor Choice

  ,                                       !- Demand Conversion Factor

  0.0;                                    !- Monthly Charge or Variable Name

UtilityCost:Charge:Simple,
  WaterTariffEnergyCharge,                !- Name
  Water Tariff,                           !- Tariff Name
  totalEnergy,                            !- Source Variable
  Annual,                                 !- Season
  EnergyCharges,                          !- Category Variable Name
  10.0;                                   !- Cost per Unit Value or Variable Name

It may be bug, but I thought I'd see if anyone else had been successful with water lifecycle costs before I filed anything.
