Carlsbad desalination plant is a desalination plant built in Encina Power station in Carlsbad in California. They took about 14 years to complete the construction for the plant. Poseidon Water is the company that invested in building the plant. The plant was put under a testing period that lasts for 6 months. The opening of the plant was celebrated with an opening ceremony.


Carlsbad desalination plant is the largest desalination plant in California. It is estimated that about 100 millions gallons of water from Encina Power Plant is being transferred to Carlsbad desalination plant daily. The salt water is being filtered with several layers of sediments to get rid of most of the particles. About half of the water transferred to the plant will turn into fresh water.

The remaining half of the water with a concentrated level of brine is discharged. This can lead to a high level of salinity in certain spots of the ocean. To reduce the impacts on the environment, they now own a wetland that covers an area of 66 acres in San Diego Bay.

The fresh water produced by Carlsbad Desalination Plant will be sold to the San Diego County Water Authority. The water will then be resold to other retails that sell drinking water. The desalinated water costs twice of the cost of the water for sale in the Metropolitan Water District of Southern California.

Metropolitan Water District of Southern California is the leading water wholesaler. It is costlier than drinking water recycled through water taken from the sewage. Many people don’t like the idea of the government’s goal in converting sewage water into drinking water in the near future of 2035.

The government has decided to increase the water bill fees to help pay for the expansion of the Carlsbad desalination plant infrastructure so that more water can be produced through desalination.

Desalination is not a new process introduced recently. It has existed in hot countries like Israel and Middle Eastern countries for many decades. Carlsbad desalination plant is designed by a company that is based in Israel. The company that designed the desalination system of Carlsbad plant is Israel Desalination Enterprises.

Carlsbad is not the only desalination plant in USA. After Carlsbad has successfully opened, the government has planned an additional 15 desalination projects to be implemented along the coastline of California. The building of Carlsbad desalination plant shows that large scale desalination plant can work in California.

Carlsbad Desalination Plant reduces greenhouse gas emission by installing solar panels. The goal of the Carlsbad desalination plant is to produce 50 millions gallons of water daily which is equivalent to 10% of the overall water supply needs for the residents in California.

The main reason why they build the Carlsbad desalination plant is because there has been several cases where San Diego experience drought. During the drought, the county has to rely on imported water because there is a scarcity of locally available clean and usable water. They hope that the opening of Carlsbad desalination plant will reduce water import by 50%.
