*Surcharge 2023/24 Bond Issue: BMU issued bonds to finance a new water treatment plant and numerous large piping projects. Customer bills will include a monthly surcharge for the financing obligation for the length of the bond issue, which is 30 years.

Each customer will be assigned a Summer Peak Usage Adjustment Level (SPUAL). The SPUAL will be set at an amount equal to 300% of the greater of the Winter City Monthly Average (WCMA) or the average of the customer’s most recent monthly usage for the monthly usage for the billing cycles ending in November, December, January and February at the customers current premise. The WCMA will be calculated each year (rounded to the nearest tenth) after the billing cycle is run in February. Any customer who does not have water usage history with the utility at the address at which service is requested shall be assigned the WCMA for purposes of computing their SPUAL.

All water consumed above the assigned SPUAL on bills dated June, July, August, will be billed at the rate of two times the published rate and two times the surcharge rate per 100 cubic feet of water.

Irrigation water rates are determined by multiplying the applicable consumption rate and service charge by a factor of 1.50. The service charge shall be $7.00 per billing cycle for the billing months of November through April for irrigation meters left in place during those months.

Rural water rates are determined by multiplying the applicable consumption rate and service charge by a factor of 1.10.
