Our mission is to effectively provide a high quality sewage collection and treatment service to our customers in a professional, economical and reliable manner, and to protect public health and the environment by adhering to the National Pollutant Discharge Elimination System Permit as issued by the USEPA.

The Carlsbad Sewage Collections System is owned, operated, and under direct supervision by the City of Carlsbad Water Department. The sewage system is gravity-fed until it reaches one of twelve sewage lift stations. It is then pumped up and allowed to gravity feed to the next station. All of the twelve stations feed one primary lift station, which pumps all the collected sewage to the Wastewater Treatment Plant (WWTP). 
The Carlsbad Wastewater Treatment Plant processes over 2.5 million gallons of sewage each day.  The plant is designed to handle as much as 6.0 million gallons of sewage per day.  The plant is an activated sludge process, equipped with primary and secondary clarification, and with chlorination and dechlorination systems for the effluent water before it is discharged into the Pecos River.  The solids handling system consists of anaerobic digesters and paved sludge drying beds.  Pathogen reduction is achieved via the composting process.  The plant produces Class A sludge which, combined with wood mulch, grass clippings or leaves, produces a premium quality soil amendment product which is then utilized at City parks and golf courses.  The compost facility is located at the Wastewater Treatment Plant.
