designed new sites to use recycled water. As a result, most of IRWD’s recycled water customers are due to new construction projects rather than retrofitting existing communities.
A. Dual Plumbed Buildings
In 1991, IRWD worked with a commercial high-rise developer to construct the first dual- plumbed commercial building in California. Dual plumbed buildings use recycled water for toilet and urinal flushing. Today IRWD serves 140 dual-plumbed commercial buildings ranging from a restroom at a park to 20-story high-rise office buildings. The list of dual buildings includes the Hotel-Hyatt House, the first fully dual plumbed hotel in the United States; this seven-story hotel is fully dual plumbed, using recycled water in all the restrooms including the 149 guest rooms.
B. Residential Landscaping
In 1994, IRWD worked with a residential developer to design large lot single-family residential properties to use recycled water for front and back yard landscape irrigation. Today IRWD serves over 700 properties in this manner.
C. Commercial and Industrial Uses
IRWD also serves recycled water for use in cooling tower operations, a composting operation, concrete production facilities, construction sites, and continually seeks opportunities to further expand the distribution system to serve any state approved uses. Examples of local commercial uses are as follows: Example: UCI Cooling Towers IRWD partnered with the University of California, Irvine (UCI) to construct approximately 3,000 feet of pipeline. This pipeline extension delivers recycled water to the campus’s central plant where it is used as make-up water in the cooling towers. This project conserves more than 250 AF of potable water each year and helped UCI achieve its sustainability goals. Example: Great Park Ice and Five Points Arena In 2017, the Irvine Ice Foundation constructed the Great Park Ice and Five Point Arena. This 280,000 square foot facility located at the Great Park in Irvine is considered the largest ice facility in California and one of the largest in the United States. Great Park Ice also serves as the official practice facility of the National Hockey League’s Anaheim Ducks. IRWD provides the facility recycled water, which us used to make and maintain the ice at the four indoor ice rinks.
