The Operations and Maintenance department also encompasses the award winning Meadowlark Water Reclamation Facility, which is capable of recycling up to 74% of the wastewater generated in the District’s service area. The recycled water is sold to neighboring water districts and is used for irrigation at Legoland, the Carlsbad Flower Fields, and the Aviara Golf Course, to name a few. The plant operators at Meadowlark are responsible to efficiently treat the wastewater through physical and biological processes to remove pollutants so that the recycled water meets all federal and state water quality standards. 

Believe it or not, some of the biggest “enemies” of the wastewater treatment process are dental floss and various personal care or disinfectant wipes, which form a mass and collect debris. These masses jam or shut down the pumps, which can increase maintenance and operational costs. You can help prevent this by learning what not to flush down the drain.

Wastewater that is not recycled at the Meadowlark Facility is treated at the Encina Wastewater Authority, which is partially owned by Vallecitos. Solids removed from the wastewater treatment process at Meadowlark are piped to Encina, where they are recycled into an environmentally friendly biofuel or fertilizer marketed as PureGreen Organic Nitrogen Fertilizer.  The recycled wastewater solids are very effective as a fertilizer and an excellent example of a sustainable and renewable resource. As a result, the District now fertlizes its Sustainable Demonstration Garden with the PureGreen Fertilizer.
