The Districts sponsor many educational opportunities including our marine biology harbor tours and 
inclass microorganism and water quality science labs. We are committed to promoting and practicing 
environmental sustainability through our community partnering and engagement programs. The 
Districts actively collaborates with community-based organizations including nonprofit groups, 
professional associations, educational institutions and other public agencies. The Districts provide 
environmental education materials, teacher resources and classroom presentations throughout 
Southern California on the importance of water quality, conservation, and sustainability to students 
from Kindergarten through College.   For the last 10 years, the Districts have also hosted an annual Earth 
Day celebration at our office in Whittier that draws anywhere from 1,500 to 3,000 visitors. The family-
friendly fair is a great opportunity for the local community to learn more about the Districts and 
environmentally sustainable practices through tours of Districts’ facilities, and over 50 exhibitor booths.  

Energy Efficiency   

The Districts started an Energy Efficiency Management Program in 2006 to maximize energy savings 
through capital improvement projects, rebate incentives, operational optimization, billing rate 
optimization and billing error corrections. Energy efficiency measures from the program accounted for 
$5.7 million in savings for the 2014-2015 fiscal year.   

The Districts are also committed to reducing fossil fuel usage and promoting alternative fuel vehicles. 
Approximately 415 employees participate in a rideshare program that provides incentives to encourage 
carpooling, riding bikes and driving alternative fuel vehicles. Currently, the Districts have 48 natural gas 
and 6 electric vehicles in the fleet and are continuing to expand our alternative fuel fleet vehicles. 
Natural gas fueling stations are also located at three Districts facilities that are open for public use.  

Energy Generation & Recovery   

The JWPCP operates a combined cycle combustion turbine facility that generates approximately 20MW 
of electricity for on-site use and steam for the plant’s anaerobic digesters, making the JWPCP virtually 
energy and heat self-sufficient. The facility uses three digester gas fired turbines and one steam turbine 
to produce green energy. During periods of low plant power demand, excess power is exported to the 
power grid. When the steam system is not operational, digester heating steam is provided by means of 
four digester gas-fired boilers.   

The Districts and USA Waste Inc. entered into an agreement to inject up to 61 tons per day of processed 
recycled food waste into an existing digester at the JWPCP. This system was placed into service in early 
2014. The addition of food waste has resulted in an increase of digester gas production and has 
generated 250 kW of electricity from the additional digester biogas produced.  

Water Reuse  

The Districts are one of the top producers of recycled water in the nation and remain strong proponents 
of expanding reuse options for reducing reliance on imported water. Over 100,000 acre-feet of tertiary 
treated recycled water produced by the WRPs is typically used at more than 800 sites throughout LA 
County each year. More than half of the recycled water used goes to recharging the local groundwater 
supply. The remaining is distributed to non-potable reuse sites. The WRPs also utilize recycled water for 
on-site irrigation, wash-down, pump cooling, chemical mixing, and toilet flushing.
