Title
Consider a resolution authorizing the Mayor to execute an Alternative Wastewater Service Billing Agreement with Round Rock Independent School District.
Body
A portion of water used in the cooling tower air-conditioning system is evaporated and not discharged into the wastewater system. Typically, all customers wastewater service is billed utilizing the water winter-average method. In 2009, the City began allowing commercial entities that utilize a cooling tower air-conditioning system to deduct the amount of water lost by evaporation from their wastewater utility bill through and Alternative Wastewater Service Billing Agreement.
Round Rock Independent School District (RRISD) recently has purchased and installed the additional meters (make-up meter and blow-down meter) necessary to accurately calculate the evaporation loss from the cooling tower air-conditioning system in three of their schools: Round Rock High School, Robertson Elementary School and Cedar Ridge High School. These meters are required to be calibrated annually to ensure accuracy of the meters. The difference in the readings from these two meters (make-up meter and blow-down meter) is subtracted from the amount of water measured at the City's water meter entering the property to determine the amount of water discharged into the wastewater system.
