NEW BUSINESS:
CWA and IID Water Transfer MOU
General Manager, Robert Greaney gave a report on the Memorandum of Understanding
(MOU) executed between San Diego County Water Authority (SDCWA) and the Imperial
Irrigation District (IID). Recently these two agencies entered into an agreement that
would provide for up to six months of continued negotiations to develop a water transfer
agreement to SDCWA from IID for up to 500,000 acre-feet of conserved water per year.
They have agreed to negotiate with other parties for the acquisition of a water supply but
not in any manner which would interfere with the MOU and the planned transfer
agreement. The MOU considers, the amount of water, the term of the agreement, price
of water and enforcement mechanism.
Metropolitan has also been talking to IID concerning the possibility of a water transfer.
Metropolitan’s position was that any water conserved was water that was to remain in the
River (Colorado) and, in accordance with the “Law of the River”, the conserved flow
would go to the next priority user. In this way MWD was planning to secure water from
the River without having to pay directly for it but, at the same time, help IlD pay for
capital programs that would conserve water.
CMWD staff believes, at this time, that while the water transfer itself is a good idea, it is
a mistake for SDCWA to pursue this water transfer.

There was some discussion regarding the water quality and possible higher TDS levels.
Commissioner Kubota made a motion and Commissioner Maerkle seconded the motion
to support staff’s opinion.
The General Manager then gave an update on the Emergency Storage Project. The
County Water Authority has four alternatives:
1.
2.
3. Expand San Vincente
4.
Moosa Canyon plus re-operation of Lake Hodges
Olivenhain Storage Project (formerly Mt. Isreal) plus re-operation of Lake
Hodges plus an expanded San Vincente
Expanded and re-operation of San Vincente
Carlsbad would prefer the Olivenhain/Lake Hodges alternate. Any neighbors of
Olivenhain would possibly benefit by being closer and having less distance and elevation
to pump.
OLD BUSINESS:
William Plummer, the District Engineer, gave a report on the status of several of the
major projects in Carlsbad.
Twin D Reservoir, an 8.5 million gallon tank and the conversion of an adjacent existing
tank to reclaimed water was completed last week. The new tank has an epoxy coating
on the interior.
Poinsettia Park Reclaimed Water Pipeline, a 12” pipeline from the Price Club to Poinsettia
Park, started construction 10/20/95. All construction activities on Price Club property and
Palomar Airport Road are performed at night to reduce traffic impacts.
Poinsettia Park Offsite Sewer - the design has started, CMWD issued a Negative
Declaration and the comment period ends on November 1, 1995. CMWD will be
reimbursed for the $4OO,OOO project by the developers benefiting from the project and
the city.
Commissioner Kubota brought up the danger of having a deep sewer as part of the
design and the safety hazards and questioned the need for a deep sewer to avoid
imparting coastal sage scrub. Mr. Plummer said the depth of the sewer was considered
for maintenance purposes. The District will use the Vactor for sewer cleaning and this
avoids the need to enter deep manholes by personnel. In addition, only thee manholes
are deeper than normal.
El Camino Real Transmission Main - 24” pipeline/PR station from Chestnut to Tamarack.
The contractor has finished ahead of schedule and the line is presently being tested.

Maerkle Reservoir Lining and Covering - CMWD is including a polypropylene material for
the floating cover, Bids are expected to be around $8 million.
North La Costa Sewer Lift Station - The capacity is 2 MGD with a single stage lift of 230’.
This project is in a preliminary design stage. Commissioner Kubota questioned pumping
this high of TDH and wanted consideration of tunneling to install a gravity sewer.
Capacitive Deionization - Process: Water Desalination using carbon aerogel electrodes.
This process is currently being studied at the Lawrence Livermore National Laboratory
(LLNL). Mr. Plummer explained the process of how the ions are removed from the water.
CMWD along with Marley Ozone, Kansas Technology and LLNL are all teaming to construct a pilot plant for this process. CMWD will bring this to the Board on December
5, 1995.
There was further discussion of this process and Commissioner Lewis made a motion
to support staff on developing this technology, and also explore other possibilities,
Commissioner Kubota seconded.
