Wastewater and sewer calculation
California American Water's Coronado water tariff is for water service; wastewater may be supplied and billed by a separate local agency. The company calculator asks whether wastewater service applies and which wastewater area, so sewer is not a universal flat percentage of water intake and must be determined from the account/service area.
