Residents will get to weigh in on a water, sewer increase being considered by council during its next regular meetings — 7 p.m. Monday, April 28, City Hall, 11701 Community Center Drive.

The last increase in water and wastewater charges was in August 2011.

The proposed rate changes are based upon recommendations from a study that was conducted by an independent contractor hired by the city to ensure that water and wastewater charges meet the costs of providing those services.

The new rates, if approved, will go into effect June 1 and customers will notice the change on their July utility bill.

A proposed change is the flat monthly service charge of $9.75 that covers utility billing, meter reading and fixed costs would increase to $9.85. The proposed minimum wastewater/sewer charge would be $11.49, or $3.83 per 1,000 gallons with a 3,000-gallon minimum. Sewer charges are based upon a household’s winter consumption averaged from November to February. This average is multiplied by the rate of $3.83 and determines a resident’s monthly sewer rate for the year until the process is repeated. For mixed-use commercial use customers, the rates will remain the same up to 100 percent of the account’s EQR (Equivalent Residential Unit) allotment or $3.25 per 1,000 gallons. Consumption over the 100 percent EQR will be charged $5.45 per thousand gallons — an increase of 19 cents. Domestic use commercial customers will continue to pay $3.35 per 1,000 gallons.
