Stockton East Water District is a public agency responsible for providing water to agricultural, industrial, and urban customers in San Joaquin County, California. The district was established in 1947 and serves a population of over 250,000 people. The district covers an area of approximately 140 square miles and has a network of canals, pipelines, and reservoirs that deliver water to its customers.

The district is committed to sustainable practices and has taken several steps towards decarbonisation and reducing its carbon footprint. The district has invested in renewable energy sources such as solar and wind power to reduce its reliance on fossil fuels. The district has also implemented energy-efficient technologies and practices to reduce its energy consumption.

One of the ways the district has achieved its renewable energy goals is through corporate power purchase agreements (PPAs). A corporate PPA is a contract between a company and a renewable energy provider where the company agrees to purchase a certain amount of renewable energy at a fixed price for a specified period. The district has entered into several corporate PPAs with renewable energy providers to ensure a reliable and sustainable source of energy.

The district has also implemented a corporate energy management program to monitor and manage its energy consumption. The program includes energy audits, energy-efficient lighting, and HVAC systems, and the use of energy-efficient appliances and equipment. The district has also implemented a demand response program that allows it to reduce its energy consumption during peak demand periods.

In addition to its renewable energy initiatives, the district is also committed to reducing its carbon footprint through its water management practices. The district has implemented several water conservation programs to reduce water usage and promote sustainable water management practices. The district has also invested in water recycling and reuse programs to reduce its reliance on freshwater sources.

The district's water recycling program includes the use of treated wastewater for irrigation and industrial purposes. The district has also implemented a groundwater recharge program that allows excess surface water to be stored in underground aquifers for future use. These programs not only reduce the district's reliance on freshwater sources but also help to reduce the amount of wastewater that is discharged into the environment.

The district's commitment to sustainability and decarbonisation has earned it several awards and recognitions. In 2019, the district was awarded the Governor's Environmental and Economic Leadership Award for its sustainable water management practices. The district was also recognized by the California Energy Commission for its renewable energy initiatives.

In conclusion, Stockton East Water District is a public agency committed to sustainable practices and decarbonisation. The district has invested in renewable energy sources, implemented energy-efficient technologies and practices, and implemented water conservation and recycling programs to reduce its carbon footprint. The district's commitment to sustainability has earned it several awards and recognitions, and it serves as a model for other public agencies and organizations looking to reduce their carbon footprint and promote sustainable practices.
