 Information about your Sewer Service Charge

 The City of National City provides sewer services to about 9,000 customers. The Sewer Service bill is collected along with property taxes. Sewer bills are monthly flat rates based on water consumption of domestic water. For commercial and industrial users, the monthly chargers are variable and based on water consumption and on the strength of the sewer they generate (low, medium or high – see attached table for rates). 


The costs of sewer bill reflect the charges sufficient to support your sewer service including the cost of wastewater collection, transportation and treatment.


For its part, the City of National City works diligently to reduce internal costs and continues to be one of the lowest cost sewer service providers in San Diego County.
