Winter Average Volume (WAV)

Date Posted:

SprinklerMembers run WAV (Winter Average Volume) by cycle to calculate Winter Average Consumption for Sewer billing.  This process is configured and executed according to each individual business policy.  Members are using this process to calculate usage during the winter months.  This usage is then set within each customer’s account, so that throughout the year, sewer can be billed out no more than what was set for winter usage.

Typically Cities use a range of November – March as their winter months.  This process benefits residents during the summer months when more water usage is typically being used.  Water usage, such as watering lawns, does not go down City sewer.  The WAV (Winter Average Volume) process ensures that sewer is being calculated according to what each resident’s typical billable sewer usage is.

It’s important to note that each Member does use the WAV (Winter Average Volume) process a little differently. A typical example of how WAV is used is as follows:

February Billing (Winter Quarter of water for Nov./Dec./Jan.)

  • Water Consumption was: 15 units
  • WAV (Winter Average Volume) is set to: 15
  • Water and Sewer for this billing is billed out at 15 units

October Billing (Summer Quarter of water for July/Aug./Sept)

  • Water Consumption was: 24 units
  • WAV (Winter Average Volume) is set to: 15
  • Water is billed out at 24 units and Sewer is billed out at 15 units (otherwise known as lesser of current or winter)

Spend any time outdoors and you know Minnesota is within those winter months.  For our members:

  1. Please remember to run the WAV process BEFORE calculating your winter quarter cycle billings.
  2. Before doing the WAV process, make sure all water readings have been uploaded in CIS, including re-reads.
  3. Make any necessary corrections of water readings in CIS.
  4. After the above steps have been completed, you are now ready to calculate the cycle billing.
