How the Plant Works


While “wastewater treatment” may sound simple, it involves a number of physical, chemical and natural biological process steps and “stations” to get the job done. The three major treatment levels are primary, secondary and tertiary treatment. By the time that process is completed, the water is clean enough to meet all standards for either recycled water use or discharge into San Francisco Bay. The Plant currently produces and delivers about an average of 150 million gallons of recycled water per year. Throughout the treatment process, the Plant staff focuses with great attention on these imperatives, safety, compliance, efficiency and cost effectiveness.
