Carmel Area Wastewater District is organized into three primary functional units. The operation of the district on a day-to-day basis is administered by the General Manager with the three functional units reporting to the GM on their areas of responsibility. The GM reports directly to the Board of Directors.

Collections is responsible for the repair and maintenance of the District’s collection system and pump stations. Personnel monitor and evaluate efficiency and effectiveness of the system and coordinate collection system activities with the treatment plant. The collection crew are the employees that the public is most likely to have contact with as they will see them around town as they clean lines and perform other duties.

Treatment is responsible for the operation and control of the wastewater treatment plant. Wastewater treatment is the process of removing contaminants from wastewater and includes physical, chemical, and biological processes. Its objective is to produce an environmentally-safe effluent and a solid waste (or sludge) suitable for disposal or reuse)

Administration includes engineering, accounting, human resources, and support to the Board of Directors.

The District also operates a water reclamation facility as part of the CAWD/PBCSD Reclamation Project, whereby the wastewater from the homes and businesses we serve is cleaned using biological and chemical treatment so that the water can be returned to the environment safely to augment the natural system from which it came. The water produced at our facility is used to irrigate seven golf courses, athletic fields, and other recreational areas within Pebble Beach

The Role of Micro-organisms in wastewater treatment

There are two types of microorganisms at work in an activated sludge sewage treatment plant. They both work to clean the water and produce energy:

Aerobic bacteria work on the raw sewage in the presence of oxygen to produce carbon dioxide and more bacteria. Essentially they “burn up” the fecal or organic matter with their metabolic processes. Going into the aerobic chambers the waste water contains fecal matter and dissolved organics. Leaving the area it contains only microbes and water. The water is separated into clean water and microbes. The water is discharged and the microbes sent off for recycling or disposal.
The collected aerobic bacteria are directed into anaerobic (no air) digestors where a colony of anaerobic bacteria live, The anaerobes eat the aerobic bacteria reducing them to methane which is burned to power the plant and an inert organic mass which can be disposed of by incorporation into the soil or incineration. CAWD disposes of its bisolids by application to cotton fields in southern California.
