Peak Use Charges

The peak use charge is used to recover the costs of constructing the facilities required to meet peak capacity demands. Only those customers whose water use patterns place peak capacity demands on the water system are subject to the peak use charge.

Your winter quarter consumption, which is based on water use during the billing cycle ending in February, March or April of each year, serves as the basis for calculating the peak use charge. Winter quarter consumption is updated each June 1st. The peak use charge does not appear on your bill until you have had a full winter quarter.

Peak use charges apply to water use exceeding 1.3 times the preceding winter quarter consumption or 6,000 gallons above the preceding winter quarter consumption, whichever is greater. Only two of the four quarterly bills you receive each year are subject to peak use charges - those based on meter readings taken June through November.

Effective April 1, 2017, peak use is billed at a rate of $3.80 per 1,000 gallons. This is in addition to the Water Usage Charge ($2.81 per 1,000 gallons) which applies to all consumption.

For monthly customers, your winter month consumption, which is based on water used during the cycle ending in March of each year, serves as the basis for calculating the peak use charge. Charges apply to water use exceeding 1.3 times the preceding winter monthly consumption. Only six of the twelve monthly bills you receive each year are subject to peak use charges those based on meter readings taken May through October.
