Water Service/Meter Installation

To ensure the timely installation of the water improvements, fees should be paid at least six weeks prior to the requested installation date. Please complete the top portion of the application form and return it to the San Dieguito Water District’s offices with the appropriate fees/deposit.

If the project is associated with a City of Encinitas Grading, Building, or Improvement plan, please submit an approved copy with the application.

A valid Building Permit will be required prior to the installation of all water meters.

Temporary Construction Meters (For Use on a Fire Hydrant)

To ensure the timely installation of the temporary construction meter, deposits should be paid at least 48 hours prior to the requested installation date. Please complete the top portion of the tanker meter application form and return it to the San Dieguito Water District’s offices with the appropriate fees/deposit.

Please include the location of the hydrant where the construction meter is to be set and the project location.

If the temporary construction meter is to be hooked up to a hose or piping system, a backflow preventer will be required. The San Dieguito Water District does not provide the backflow assembly.

An additional charge of $125.00 will apply to relocate the temporary construction meter.

Recycled Water Program

The San Elijo Joint Powers Authority operates and maintains a recycled water distribution system within a portion of the San Dieguito Water District. It is the District’s policy that recycled water be used for any purpose approved for non-domestic water use to the maximum extent possible.

The San Dieguito Water District’s Recycled Water Rules and Regulations govern the requirements for recycled water use within the District’s jurisdiction.

Prior to the construction of new facilities or the retrofit of existing facilities that will use or receive recycled water, design plans must be approved by the District, San Elijo Joint Powers Authority, and the San Diego County Department of Environmental Health.

Click here to see San Dieguito Water District’s recycled water permit process.

The County of San Diego’s Recycled Water Plan Check and Inspection Manual (DEH 2001 Edition) can be viewed here.

Prior to starting recycled water service, a completed Recycled Water Check List and Application (construction and/or irrigation) must be completed and returned to the District.

Capital Improvement Projects

CW16D  Abandon 30-inch Transmission Main / SEJPA RW Fire Protection

The District’s 2010 Water System Master Plan identified the abandonment of the 30-inch transmission main as a high priority project due to the fact that it was nearing the end of its service life.  The project will abandon the final 1,750 LF of 30-inch transmission main from the Cambridge Yard to the San Elijo Water Reclamation Facility (SEWRF) located at 2695 Manchester Avenue.  This project will improve the water quality in this location, which will decrease the need for District staff to flush water mains in the area.

Abandoning the transmission main will require the replacement of the fire protection system at the SEWRF.  The project will convert the fire hydrant and fire sprinkler service from potable water to recycled water through the construction of 170 LF of 12-inch PVC and 275 LF of 8-inch PVC recycled water mains.  Hunter General Engineering was awarded the project in August of 2016 in the amount of $348,700.  The project is currently underway and is anticipated to be completed by March 2017.

   CW16X  NCTD Water Main Replacement

This project provides for the replacement of 170 LF of 10-inch steel main within North County Transit District (NCTD) right-of-way (under the train tracks) near Encinitas Blvd in response to a water main break that occurred in March 2016.  PAL General Engineering was awarded the project to complete the replacement.  Work is currently complete, and the Notice of Completion will be taken to the Board in March 2017.


CW17D  Non-Destructive Pipeline Assessment

The District’s 2010 Water System Master Plan included an advanced asset management methodology to optimize the replacement of District pipelines. The methodology combined the estimated useful life of a pipeline with the consequence of failure of the pipeline to determine a business risk exposure ranking.  District staff identified 12 miles of pipeline that should be tested due to the age or critical nature of the pipe.  Most of the asbestos cement pipelines (ACP) chosen were constructed in the 1950s and 1960s, so the pipes’ ages range from approximately 50 to 65 years-old.  The estimated useful life of ACP is 60 to 80 years.  By testing the structural integrity of the pipeline wall, the District can assess whether these pipelines can continue to be used beyond their estimated useful life, thereby deferring significant pipeline replacement costs.

The District awarded the non-destructive testing to Echologics for the amount of $242,860.  The project is currently underway and is estimated to be completed in April of 2017.

CW17H  Balour Reservoir Rehabilitation

The Balour Reservoir is a 2.5 million gallon potable underground concrete reservoir located under a soccer field at the Oakcrest Middle School.  Its main purpose is to store potable water that is to be distributed to the eastern portion of the District.  The Reservoir was constructed in 1975 and has only required minor repairs over the last 41 years. The rehabilitation includes cleaning and re-caulking floor and wall joints; replacement of the 16-inch butterfly outlet valve, and the 8-inch butterfly drain valve; installation of cathodic protection on inlet, outlet, and drain pipes; and the repair of existing patches with concrete mortar.  The contractor will then clean, disinfect, and perform bacteriological sampling of the Reservoir per American Water Works Association specifications (AWWA C652-11).
DN Tanks, Inc. was awarded the project in November of 2016 for $182,975.  The project is underway and is estimated to be completed by early March 2017.

Construction Inspection

The primary role of the San Dieguito Water District’s Construction Inspection Division is to ensure that all new District facilities are installed in accordance with the approved plans and the Water Agency Standards. The Construction Inspection Division is involved with all Developer and CIP projects, including potable and recycled water.

The Contractor shall notify the District's Construction Inspection Division at least 48 hours in advance of beginning work to arrange for inspection of the project. All work performed without benefit of inspection will be subject to rejection and removal.

The Contractor will be required to schedule a mandatory pre-construction conference with a San Dieguito Water District inspector prior to commencement of work on water improvements.

To be assigned an inspector and schedule the required pre-construction meeting, please call the Engineering and Planning main line at (760) 633-2709.
