GCSD was required to provide advanced wastewater treatment prior to discharge to Atascadero Creek by October 7, 2007, by the North Coast Regional Water Quality Control Board (NCRWQCB) NPDES Permit No. CA0023639. The current wastewater treatment system consists of secondary treatment for an average daily dry weather flow of up to 0.14 million gallons per day and an average daily wet weather flow of up to 0.85 mgd. The existing system is comprised of two influent pumping stations, two facultative aerated ponds, a settling pond, chlorine disinfection system, and a dechlorination prior to discharge to two effluent storage ponds. The effluent storage ponds have a total capacity of 23 million gallons. Discharge is to irrigation sites or to surface water.
