Source Control

The purpose of Pretreatment and Source Control is to manage wastewater dischargers to enhance the ability of Carmel Area Wastewater recycling plants to comply with National Pollutant Discharge Elimination System (NPDES) requirements; to protect the public, the environment, CAWD personnel and facilities; and recovery of wastewater treatment operations and maintenance costs.

The wastewater collections system is comprised of the CAWD Sewer Systems which conveys wastewater to the treament plant that can be processed for other uses. 


What is the FOG Program?

Carmel Area Wastewater District (CAWD) maintains a public sewer system for businesses and is required under CAWD's Sewer System Management Plan (SSMP) to comply with the California State Water Resources Control Board to implement a comprehensive fats, oils and grease (FOG) control program to prevent the discharge of FOG into the sewer system. FOG from restaurants or other food service establishments is a major cause of sewer issues.  These sewer issues can spill into the Stormwater drain systems and other waterways causing pollution in our waterways. 

Who must submit plans to CAWD for a plan review?

Any person or entity planning to develop, remodel, or build a food service establishment, including food processing or manufacturing facilities should submit plans for review to the District Engineer Rachel Lather at (redacted)

Can dishwasher drainage be connnected to the Grease Trap or Interceptor?

Dishwashers are not to be connected to drainage pipes conveying wastewater to an interceptor or any other grease removal device. This would include the dishwasher pre-rinse sink, which must be connected to the Grease Removal Device. 

Does my facility require a Grease Trap or Interceptor?

Yes, All food service establishments or food processing/manufacturing facilities must be equipped with a grease interceptor or grease trap which are designed to limit the discharge of fats oil and grease into the District's sewer system. The size of the grease trap or interceptor of the food service establishment will be reviewed by the District Engineer from the plans submitted. 

Compliance staff are in the field conducting Fats,Oil and Grease (FOG) inspections.
