Water Reuse Study E-Update - January 2005

The Water Reuse Study team has created this "E-Update" to bring you up-to-date on Study activities and provide news about the recycled water industry. Each issue will be posted on this website. We are sending e-mail announcements of new issues to persons who have expressed an interest in the Study. If you did not receive an e-mail announcement and would like to, please join our news group. If you did receive an announcement about this issue, you are automatically in the news group.

If you are new to the Water Reuse Study, the Study Overview will provide helpful background information. The Frequently Asked Questions section contains additional material that also may be of interest.

Impact of Local Rainfall on Recycled Water

Now that we are in the midst of San Diego's rainy season, it's an appropriate time to consider how local rainfall impacts the demand for and production of recycled water. San Diego's rainy season typically extends from November through March with an average annual rainfall of approximately 10 inches. Our season got an early start this year - October 2004 set a record for rainfall in that month with over 6 inches measured at Lindbergh Field. For information on rainfall measured at Lindbergh Field, visit http://www.wrcc.dri.edu/cgi-bin/cliMONtpre.pl?casand

While the availability of wastewater flows that are used to produce recycled water is relatively constant throughout the year, the demand for recycled water varies seasonally. Because recycled water is used primarily for irrigation, the demand for it increases during the summer and decreases in the cooler and rainy months.

Addressing the seasonality of demand for recycled water is a key aspect of the Water Reuse Study. The Study will explore the feasibility of a number of uses for excess recycled water produced during the rainy months. Options include storing recycled water for later use, creating wetlands, recharging groundwater basins and augmenting reservoirs. Implementing these additional uses for recycled water during times of low irrigation demand will help to fully utilize the plant capacity year-round.

Recycled Water Education Efforts

One of the best ways to increase the awareness of recycled water and its importance to our local water supply is to proactively educate San Diego's young residents on this topic. Water recycling and wastewater treatment are included as part of the State's elementary level science curriculum, so our local students get early exposure to this important topic.

To supplement information that students receive in school, tours of the North City and South Bay water reclamation plants are offered to students and school educators. These tours offer a first-hand look at how the treatment process works and further educates students and teachers about the beneficial uses and importance of recycled water. Approximately 130 tours are given each year.

Tours are offered to students in 4th grade and above. To schedule a water recycling facility tour, please call (858) 294-6484 or visit http://www.sandiego.gov/mwwd/general/speakers.shtml. In addition to the tours, Water Reuse Study team speakers have given presentations to high school and university level students on the subject of water recycling.

Water Conservation 2005 Wall Calendars Now Available

The City's popular Water Conservation wall calendars have just arrived. Each month of the calendar features artwork by a San Diego student in the 1st through 6th grade and has an informational theme related to water conservation.

The theme for July 2005 features recycled water and the artwork was provided by a San Diego 1st grader. This theme emphasizes the importance of recycled water in keeping our City green, and encourages public support of projects that will help increase the use of recycled water.

Supplies of the calendar are limited. If you are interested in receiving a calendar, contact the Water Reuse Study info line at (619) 533-4631.

Reminder - California WateReuse 2005 Conference in February

The third annual California WateReuse 2005 Conference will be held in San Diego from February 27-March 1, 2005. The focus of the 2005 forum is "Water Recycling: Realizing California's Potential." This conference is sponsored by the California Section of the WateReuse Association, a national organization that promotes the use of recycled water and provides a forum for professionals in the water recycling industry.
