With San Diego County well on its way to a record year for rainfall, it is very easy to forget that we live in a desert. No matter how much rain falls, we must remain alert to the need to diversify our water supply, and conserve water even when it seems to be abundant.


While recent rains have abated a drought situation by filling our local reservoirs and replenishing our local groundwater basins, San Diego County gets only 10 percent of its water supply from local sources. The rest is imported, primarily from the Colorado River basin. With increasing growth in western states that all rely on this single supply, every gallon of water that can be saved is a gallon that we do not need to import.


A reliable, diversified water supply is crucial not only for residents, but for business and industry. Having a guaranteed water supply is imperative for companies as they make decisions whether to location research, development, and manufacturing facilities in San Diego County.
According to the San Diego County Water Authority, half of all residential and commercial water use in San Diego County goes to outdoor irrigation.


One way to reduce the use of imported water is recycling water for safe and appropriate uses such as landscape irrigation at commercial and industrial sites, such as schools, golf courses, parks, greenbelts, and common areas of homeowners associations. Every drop of water that can be recycled and used for commercial irrigation is one more that can be for home or office use.
The City, which has been at the forefront of building a recycled water system for commercial use, is expanding to meet irrigation water needs. Since recycled water is used for non-drinking uses, a separate set of distribution pipelines must be built to deliver recycled water.


The City of Carlsbad's Recycled Water Pipeline Project is part of Phase II, the second of four projects phases, that make up the Encina Basin Water Reclamation Project. It involves the construction of over 24 miles of pipelines ranging in size from four to thirty inches in diameter starting in late March and continuing for approximately one year.


David Ahles, Senior Civil Engineer, says pipelines will serve dozens hundreds of potential customers in the Carlsbad Research Park, as well as homeowners associations. Eventually, at the completion of Phase II, the Carlsbad Municipal Water Utilities District hopes will be able to supply 25 percent of the entire city's water needs with recycled water.


It's important to note that recycled water is a more reliable water supply in the case of a drought.
“I like to tell business and homeowners associations that this (recycled water) is like an insurance policy on your landscaping,” said Ahles. “Some of these places have hundreds of thousands of dollars investing in beautiful landscaping that would all be lost during a drought. Restricting outdoor watering is the first thing we would do. So it's insuring against the value of your landscaping.”


The City of Carlsbad has approximately 26 miles of existing recycled distribution pipeline, constructed as part of Phase I in 1997. Ahles says it's been a great success, currently supplying 58 recycled use sites including La Costa Resort and Spa, Four Seasons Resort Aviara, LEGOLAND California, Grand Pacific Palisades Hotel, and the world-renowned Flower Fields. It is also supplied to parks, median strips, shopping areas, freeway landscaping and numerous homeowners associations.


Ahles says it is the responsibility of each individual business and association group to connect to the recycled water system. New irrigation services will be provided to each property along the recycled water pipeline route. However, connecting each property to the recycled water irrigation service is not part of this construction project.


“We're starting site reviews for customers now,” says Ahles. “We're in the process of contacting property owners. We go out to each site and determine what it would take and identify those needs.” Ahles encourages anyone interested in learning more and getting specifics now to get in touch with his department now.


Ahles acknowledges the construction will create a temporary inconvenience for drivers and businesses along major surface streets such as Faraday Avenue and Rutherford Road. The construction will not affect water service, but may affect traffic patterns and the availability of street parking in certain areas. To minimize the impact, construction hours will be limited on streets between 8:30 a.m. and 3:30 p.m. to avoid morning and evening commute times. Construction in major intersections will be limited to weekend and overnight hours.


Temporary road patches will be used until the entire project is completed in early 2006. At that time, the major surface streets will all receive full width pavement overlays and sidewalk repairs to return the streets to their original condition or better.


Ahles encourages anyone with questions to visit the City's Web site at www.ci-carlsbad.ca.us, or to call him at (760) 602-2720.
